DJI Osmo Pocket 4, Recteq X-Fire Pro and Alienware 27 QD-OLED

Published

on

Engadget’s hottest review roundup truly has it all this week: a new pocket cam, a 2-in-1 smart grill, a pair of drones and a pricey skinny vac. And that’s before we even get to the highly capable gaming display that will only set you back $350. Read on to catch up on the reviews you might’ve missed over the last two weeks as we prepare for another slate of big events next month.

The Osmo Pocket 4 is still the best pocket-friendly vlogging camera you can buy. With excellent image quality, improved photos, great stabilization and pro D-Log mode, it’s incredibly easy to record everything from simple vlogs to near cinematic-quality video. The high level of portability and extended battery life make this an easy camera to reach for whatever you’re filming.

Pros

  • Excellent image quality
  • Improved low-light performance
  • Onboard storage
  • Modular accessories
Cons
  • Still only 3K in portrait mode
  • No dust or water protection due to the gimbal
  • No optical zoom
  • Not available in the US

DJI’s Osmo Pocket cameras have become a staple of Engadget’s live event coverage over the last few years. They’re convenient, compact and product high-quality footage when speed matters. Contributing review reporter James Trew recently put the new Osmo Pocket 4 through its paces, concluding that “you’re getting better image quality that will pay you back over time.”

Recteq X-Fire Pro 825

The X-Fire Pro offers the ease of gas with the wood flavor of pellets in the same grill. While there could be more features, the build quality is excellent and the performance is reliable.

Pros
  • Two grills in one
  • Reliable Wi-Fi tools
  • Robust build quality
  • Direct-flame searing
Cons
  • Small pellet hoppers
  • No super smoke, keep warm or other handy modes
  • Not compatible with wireless food probes

With the X-Fire Pro, Recteq set out to make a pellet grill that would appeal to fans of gas grills. The company has done just that, offering a dual-mode device that imparts wood flavor you don’t inherently get from propane or natural gas. “Recteq has successfully combined the best aspects of pellet grills with a dedicated high-heat mode and separate controls that will be familiar to gas grillers,” I said. “This model offers robust build quality, reliable performance and Wi-Fi connectivity for extended smoking sessions.”

Alienware 27 QD-OLED monitor

In a world where every piece of gaming gear seems to be getting more expensive, Alienware’s  $350 AW2726DM 27-inch QD-OLED monitor feels like a gift to gamers on a budget.

Pros
  • Stupendously affordable
  • Three-year warranty with burn-in protection
  • Simple, straightforward design
  • QHD resolution with 240Hz VRR
  • Rich colors
Cons
  • Mediocre brightness
  • Not a ton of ports
  • No native G-Sync support

Can a $350 gaming monitor offer enough to get the job done? If you’re talking about the Alienware 27 QD-OLED display, that answer is a resounding “yes.”

“The AW2726DM might not have all the fancy features you get on more expensive monitors, but it’s an excellent example of a no frills gadget done right,” senior reporter Sam Rutherford said. “You get just enough ports, a straightforward design and a beautiful QD-OLED panel with a solid resolution and refresh rate — all for just $350.”

DJI Lito drones and a Dyson PencilVac

Like the Osmo Pocket 4, DJI’s latest Drones are unlikely to make it to the US. However, if you live elsewhere, there’s a lot of performance available for under $400. “The Lito series shows that DJI is intent on dominating every drone price range and category, including the bottom end,” contributing reporter Steve Dent said. “Despite their low prices, the new drones don’t skimp on features, offering full obstacle protection, ActiveTrack subject tracking, relatively high speeds and sharp 4K video quality — just like models that cost a lot more.”

If your spring cleaning could still use a jump start, perhaps a fancy, skinny vacuum could do the trick for light duty. “With its minimalist form factor, the PencilVac is still an engineering marvel,” UK bureau chief Mat Smith said. “Its high degree of mobility makes it easy to clean in tight corners and between furniture. I just wish it were slightly more powerful.”

Consumer Reports Says This Simple Habit Can Save You Big On Gas

Published

on





Disruption caused by the continuing war in Iran has led to gas prices rising across the country, while tariffs have pushed up costs for many other consumer goods in 2025 and 2026. Drivers looking to offset these increased expenses will want to make sure that they’re not spending more at the gas station than they have to, and that means they’ll want to take advantage of as many fuel-saving tips and tricks as possible. A recent study by Consumer Reports found that one tip in particular can save drivers hundreds of dollars on gas per year, and it won’t take any effort to implement either.

The study found that driving 10 mph slower than usual on the highway can make a surprisingly big difference, with CR reporting that its test team recorded efficiency increases of up to 8 mpg. The average new car in 2024 achieved 27.2 mpg, but drivers of cars that get 35 mpg or more could save over $400 annually at the gas pump by cutting their speed. For habitual speeders, slowing down has the added benefit of reducing the chance of an encounter with local law enforcement.

Setting a slower cruising speed is far from the only way to avoid wasting fuel. Among other things, accelerating more slowly to reach your cruising speed and removing heavy, unnecessary clutter from your car can also help reduce fuel costs.

Modern cars are more efficient than their predecessors

While drivers can make a significant difference to their fuel costs by altering their driving style, modern cars feature several systems designed to reduce fuel usage without the driver doing anything at all. One of the most noticeable modern fuel-saving systems is auto start-stop. A 2022 study published in the Environmental Pollution journal found that start-stop systems can reduce fuel usage by more than 4%, with drivers in warmer climates seeing bigger efficiency increases than those in colder climates.

It’s sometimes claimed that using start-stop is bad for your engine, but modern engines are designed to accommodate the technology, so it won’t cause significant additional wear. However, drivers of cars without start-stop shouldn’t attempt to turn their cars off at junctions or intersections to save fuel. It usually won’t increase efficiency, and it might prematurely wear out the car’s starter motor, since the motor isn’t designed to be repeatedly used during a journey.

Other fuel-saving systems are less noticeable, such as variable valve timing (VVT) systems. The first engine with VVT was designed by Alfa Romeo in the ’80s, but it has since been adopted by many major automakers. Turbochargers and continuously variable transmissions can also help save fuel, along with many other hidden fuel efficiency technologies in modern cars. However, even the most technologically advanced, fuel-efficient car should see its efficiency increase when drivers reduce their speed by a few mph.

Vampire Crawlers, Peter Molyneux’s return and other new indie games worth checking out

Published

on

Welcome to our latest roundup of what’s going on in the indie game space. If you’re looking for something new to play this weekend, we’ve got a bunch of options for you. We’ve also got some interesting upcoming games to tell you about as well.

In a press release announcing that Playdate Season 3 is coming later this year, Panic included a line that I’ve been thinking about a lot this week. “Panic is currently relieved and happy that people can make amazing games for Playdate with just 16 megabytes of RAM,” it said, a nod toward the ongoing RAM crisis.

The Playdate doesn’t exactly have a lot of technical oomph, and I’m frequently delighted by what developers are able to do within its limitations. Restrictions foster creativity — many folks had to get pretty inventive on Twitter back when they only had 140 characters to play with. Here, Panic offered a welcome reminder that you don’t necessarily need an ultra-powerful rig or console to have access to more great games than you’ll ever actually be able to play.

For instance, my favorite game of the year so far, Titanium Court, works on Macs that are capable of running macOS 11 (the 2020 version of the operating system) or later. On PC, you’ll need a graphics card that’s compatible with OpenGL or DirectX 9, the latter of which was released in 2002. For what it’s worth, the game would also fit on a CD-ROM.

There are tons of other great indie games new and old that’ll run just fine on lower-powered machines. Bear that in mind the next time a current-gen console or other gaming system gets a price increase because of the RAM shortage. The DLSS 5 debacle aside, you probably don’t need a 50-series NVIDIA GPU either. Maybe just pick up a Playdate instead.

New releases

While many of the weapons, characters and enemies are the same, Vampire Crawlers is a fresh spin on Vampire Survivors. It’s a turn-based roguelite deckbuilder. Instead of automatically firing whatever weapons you have at nearby enemies, you’ll play cards to conquer the mob that you face in each fight. You can still modify and evolve your weapons and abilities.

Each card has a casting cost, so you’ll need to consider which ones to play in a given moment and the order in which you do so. As such, it’s a slower-paced, more strategic take on the original game, albeit with a similar level of visual chaos should you put together a particularly powerful build.

I’ve played a ton of Vampire Survivors and the Vampire Crawlers demo lured me in too. Its approach to turn-based battles is working for me. I’ve only played a little of the full game so far, but there’s every chance I could lose days of my life to it.

Vampire Crawlers — from Survivors creator Poncle and co-developer Nosebleed Interactive — is available now on Steam (for PC and Mac), Xbox for PC, Xbox Series X/S, PS5 and Nintendo Switch for $10. It’s included with Game Pass Ultimate and PC Game Pass.

Fable creator Peter Molyneux and his studio 22cans are back with another god game. In Masters of Albion, you can construct and modify settlements as a literal hand of god. You’ll design buildings (which are immediately constructed and usable) and manage workers. You can also assume control of a human or animal in the world to take on quests and hunt for treasure.

There’s a tower defense element to this as well. You’ll need to prepare your towns from nighttime attacks from various creatures. You can fend off these foes as the god or battle them on the ground as a hero. There’s a lot going on here, but perhaps my favorite part is this apparent warning in the mature content description section of the Steam page: “Players are also able to use crude, adult hand gestures at will in the game.” Yes, that means you can flip the bird while playing as the god hand. Yes, I am very mature.

Masters of Albion is now available in early access on Steam. It typically costs $25, but there’s a 10 percent discount until April 29.

Snap & Grab caught our attention at last summer’s edition of the Day of the Devs showcase. This is a cartoonish heist game in which you’ll carry out your robberies in two parts. You play as Nifty, a famous fashion photographer. In the setup phase, you’ll take advantage of your position to take snaps of loot, threats and opportunities and then use those to construct a plan. With the help of some henchman, you’ll then try to execute the heist.

The game’s developer No Goblin is taking an episodic approach to Snap & Grab as it’s releasing the game in five parts over the course of this year. The first episode is available now on Steam (usually $8, though there’s a 10 percent discount until May 1).

Snow Day Software’s follow-up to Indoor Kickball is Indoor Baseball. It’s an arcade game in which you play baseball inside buildings, funnily enough. You’ll play 1v1 matches against the CPU or a friend in local multiplayer. You can also dive into a 14-game season or check out the story mode, in which you’ll try to play your way back onto your school’s baseball team (and maybe do some chores to make up for smashing too many things at home).

There are several different levels, each of which has a variety of ways for you to make a home run, from smashing a window to landing the ball in a toilet. It seems light and fun and as a burgeoning baseball guy, I dig the idea of this one.

Indoor Baseball is available now on Steam, Xbox for PC, Xbox One, Xbox Series X/S, PS5 and Nintendo Switch. It costs $15.

Upcoming

I love Another Crab’s Treasure very much and so I’ll always be interested in whatever Aggro Crab is up to. Given that the studio also co-developed the smash hit Peak (alongside Landfall), I imagine many other folks feel the same way.

Crashout Crew is another multiplayer game from Aggro Crab. This one adopts the chaotic co-op formula of games like Overcooked. As a team of forklift drivers, you and your buds will work together to fill orders in warehouses while dealing with obstacles like blackouts, cacti, fire and bees.

It’s coming to Steam, Xbox on PC and Xbox Series X/S on May 28. It’ll be available on Game Pass on day one.

I’m very much here for slice-of-life games based around soccer (I still need to play Despelote!). Kick is another such title. This is a side-scrolling, anime-inspired game from solo developer nospacelost and publisher Shoreline Games, in which you dribble a ball as you make your way to school.

There are 23 levels with people to dodge and obstacles to overcome. You’ll need to avoid damaging anything as you try to pull off tricks by kicking the ball at the correct angle, all while making sure you get to class on time (you can switch off the timer for a more relaxed experience). It looks pretty, and it never hurts a game’s prospects to have a pup accompanying the main character.

No release date for Kick has been announced. It’s coming to Steam at some point.

Elfie: A Sand Plan is a cozy sandcastle building game from Pressed Elephant and Sol’s Atelier. There are more than 180 levels in which you’ll build sand sculptures to match what Elfie, a small elephant, has in mind. There are three difficulty levels too.

Advertisement

It looks cute and I adore elephants (oops, I just started fostering another one), so I’m interested in checking it out. Elfie: A Sand Plan is coming to Steam for PC and Mac on May 12. It’ll cost $7, and there’ll be a 10 percent launch discount.

It took the team at Realmsoft 14 years to bring Clockwork Ambrosia to fruition and if this latest trailer is any indication, that long development cycle could have well been worthwhile. This is a side-scrolling action platformer in which you can customize half a dozen weapons using more than 150 modifiers.

You play as an airship engineer who tries to survive on a steampunk island full of aggressive robots and creatures following a crash. I really dig the art direction here, which features lush hand-drawn pixel art and lovely animations. Realmsoft made the game using a custom engine the team built from scratch.

I’m looking forward to checking out Clockwork Ambrosia. It’s coming to Steam on May 12.

FDA Gives Green Light To the First Gene Therapy For Deafness

Published

on

An anonymous reader quotes a report from NPR: The Food and Drug Administration approved the first gene therapy to restore hearing for people who were born deaf. The decision, while only immediately affecting people born with a very rare form of genetic deafness, is being hailed as a milestone in the quest to treat hearing loss. “It’s the first time in history there’s a new drug for hearing loss,” says Zheng-Yi Chen, an associate scientist at Mass Eye and Ear in Boston who was not involved in the development of the therapy approved by the FDA Thursday. But his research team reported very promising results with a similar approach Wednesday. “I think it’s an historical event, a landmark, a great development for the whole field,” he says of the approval. […] The FDA’s decision was based on the results from the treatment of 20 patients born with a defective version of a gene known as OTOF, which is necessary to transmit sound from the ears to the brain.

Doctors infused billions of adeno-associated viruses into the patients’ ears by making a small incision behind the ear to open a small hole in the skull. The viruses carried a healthy version of the OTOF gene that had been split in half to fit inside the virus. The gene provides instructions to make the otoferlin protein, which is necessary for hair cells in the inner ear to transmit sound to the brain. Most of the patients began to hear for the first time within weeks, with the quality of their hearing improving over the following months, according to [Regeneron Pharmaceuticals, which developed the gene therapy and plans to offer it for free in the U.S. It should be available within weeks.]. The amount of hearing patients gained varied, but 80% achieved at least some significant hearing restoration and 42% ended up with normal hearing, which included the ability to hear whispers, Regeneron says. The hearing ability has lasted at least two years so far.

The treatment can only help patients with the very rare form of deafness that Smith was born with, which only affects about 50 children each year in the U.S. But similar gene therapies are showing promise for other forms of genetic deafness. And researchers hope someday gene therapy may help with common types of hearing loss, like from aging and loud noise.

Belfast’s Cloudsmith eyes ‘massive growth’ with $72m raise

Published

on

The company raised $23m last year to expand its workforce.

Belfast software company Cloudsmith has raised $72m in Series C funding led by the investment firm TCV.

The raise, Cloudsmith said, would position the company for “massive growth” as it eyes the AI-generated software market. The funds will help accelerate product development and expand its go-to-market capabilities. Insight Partners and other existing investors also supported the round.

The latest funding comes just a year after the company raised $23m in a Series B to expand its workforce across departments and invest in AI R&D. TVC also led this round.

Founded in 2016 by Lee Skillen and Alan Carson, Cloudsmith helps businesses manage software on the cloud, and is used by companies that need control, security and scalability in their software supply chain. The company made two Series A raises – $15m in 2021 and $11m in 2023.

The new investment follows a period of strong year-over-year growth, Cloudsmith said, as companies seek modern infrastructure to keep pace with the speed and scale of AI-generated software.

Businesses also rely on software companies such as Cloudsmith to provide guardrails and governance when adopting AI-coding agents.

The investment comes at a time when AI coding is seeing unprecedented uptake by enterprises, which brings with it an ever-expanding threat surface.

Enterprises need to manage an growing software supply chain, while facing regulatory pressures and their own security requirements to ensure their AI-generated software is secure by design.

“AI agents generate so much software, so fast, it’s nearly impossible for humans to carefully review it all,” said Glenn Weinstein, the CEO of Cloudsmith.

Weinstein said Cloudsmith has the capacity to protect enterprises against the new kinds of threats that AI-driven development introduces.

“TCV and Insight Partners both recognise this profound shift, and their backing is helping Cloudsmith scale up for the massive wave of adoption of AI agents across enterprise software teams.”

Thomas Krane, the managing director at Insight Partners added: “In an era increasingly defined by AI-driven development, securing the software supply chain is critical.

“As a cloud-native offering, Cloudsmith is well positioned to do this – providing the scale and reliability needed to help power enterprise and AI-driven builds and mitigate emerging risks.”

This Is JD Power’s Most Reliable French Door Refrigerator Brand

Published

on





Appliances might be smarter than ever, but 2025 study data from J.D. Power suggests that they aren’t as reliable as they used to be. Senior managing director of retail practice at J.D. Power, Michael Taylor, explained that although “modern appliances are far more sophisticated and packed with more technologies than ever before,” the increased complexity of today’s appliances means that there are more systems to potentially go wrong. As a result, he said that reliability was now a “critical factor” in picking a new appliance.

According to the study, buyers looking for the most reliable French door refrigerator from a major refrigerator brand should look toward GE’s current lineup. The brand saw the lowest number of problems per 100 appliances (PP100), with owners reporting 65 PP100. GE’s score was slightly ahead of Whirlpool’s rival refrigerators, which saw 68 PP100 reported. The third most reliable brand in the segment was LG, with owners reporting 74 PP100.

French door refrigerators suffered from more problems on average than most other types of appliances. Across the category, owners reported 76 PP100 on average, while side-by-side refrigerators were subject to 68 PP100 on average. Two appliance categories shared top honors for being the most reliable on average: cooking appliances and clothes dryers. Both saw an average of 56 PP100 reported.

GE scored highly for reliability in other categories

Although it didn’t quite achieve a clean sweep, GE managed a first-place finish for reliability in almost all appliance categories in J.D. Power’s study. As well as being the most reliable French door refrigerator brand, GE also took top honors in the clothes dryer, front-load washer, and top-load washer categories, among others. However, not everyone agrees with J.D. Power’s verdict, with Consumer Reports crowning LG’s front-load washers the best on the market.

Even so, J.D. Power’s study unequivocally puts GE’s home appliance range at the top of the pile for reliability. As a bonus, when things do go wrong, the study claims that GE has the best service experience, too. The brand received 778 points for its appliance service out of a possible 1,000 points, while Samsung earned second place with a score of 768 points. Unfortunately, owners of Samsung appliances are more likely to end up testing out its appliance service than most, since the Korean brand’s appliances were subject to more problems than average in seven out of eight appliance categories.

Cohere acquires, merges with Germany-based startup to create a ‘transatlantic AI powerhouse’

Published

on

Cohere, the Canada-based enterprise AI unicorn, announced Friday that it would merge with the Germany-based enterprise AI company Aleph Alpha.

The deal, which has yet to close, will value the newly formed company at $20 billion, the FT reported. Schwarz Group, one of Aleph Alpha’s top backers, will also invest $600 million in Cohere’s Series E round, which is expected to close later this year, CNBC reported.

A handful of Silicon Valley players continue to dominate the AI commercial landscape, which is busy with consolidation activity.

A press release announcing the Cohere-Aleph Alpha union said one goal of the merger was to give businesses and governments an alternative to these dominant tech players, one that offers greater independence and control over their data. It also hopes to combine the talent pool across Canada and Germany to create a “transatlantic AI powerhouse.”

Charging is handled via USB-C; you simply detach the unit from its wall bracket, connect the included cable, and click it back into place when it’s ready, which makes the whole process considerably less disruptive than it sounds.

The Ring Battery Doorbell also connects with Alexa-enabled devices, meaning an Echo Show can display a live feed when motion is detected, and compatible Echo speakers will announce when someone arrives.

It’s worth noting that features like Smart Alerts for person and package recognition, video history, and Quick Replies each require a Ring Protect subscription, sold separately, so factor that into your running costs.

For anyone who has been putting off adding a smart doorbell to their home setup, this 40% discount makes the barrier to entry meaningfully lower than it has been.

Internal memo: Five senior execs out at Qualtrics as new CEO restructures leadership team

Published

on

Qualtrics is based in Provo, Utah, and downtown Seattle (above). (GeekWire File Photo)

Qualtrics CEO Jason Maynard shook up the company’s senior leadership team on Friday at its dual headquarters in downtown Seattle and Provo, Utah, less than three months after taking the helm of the experience management technology company.

Five executives are no longer with the company, Maynard told employees in an internal email viewed by GeekWire, calling the moves “a difficult but important step” designed to “simplify our structure and ensure we are positioned for our next phase of growth.”

The impacted leaders span Qualtrics’ business, engineering, IT,  and marketing teams: 

  • Brad Anderson, president of products, UX, engineering and security; 
  • Eddie Chen, chief strategy and corporate development officer; 
  • Jeff Gelfuso, SVP and chief product and experience officer; 
  • Juan Rodriguez Estevez, chief information officer; 
  • and Lynn Girotto, chief marketing officer. 

Anderson is the most senior of the departing execs, having been at Qualtrics for more than five years, overseeing the company’s engineers, product managers, designers, and security engineers. He previously spent nearly 18 years as a high-ranking Microsoft exec. Maynard’s email singled him out, thanking him for his leadership and impact in his role.

In addition to the departures, Maynard outlined plans for a broad reorganization, reshuffling teams across marketing, customer operations, IT, and corporate development. He said in the memo that a new SVP of marketing would be named Monday, and more details will be announced internally next week. 

It’s not clear how many employees were impacted by the changes overall. Qualtrics is not yet commenting publicly on the changes.

The priority is to “ensure we build with speed, clarity, and a relentless focus on driving stronger outcomes for customers and bringing new AI capabilities to market faster,” Maynard wrote.

Maynard took over as CEO on Feb. 3, succeeding Zig Serafin, who stepped down in October 2025. (Jim Whitehurst and Mark Gillett had served as interim co-CEOs in the meantime.) Maynard previously spent a decade at Oracle, where he was executive vice president of revenue operations, joining through the NetSuite acquisition in 2016.

Qualtrics, which employs more than 4,500 people globally, makes software that helps companies gather and act on feedback from customers, employees, and others through surveys, AI-powered analytics, and other tools. It was taken private by Silver Lake and Canada Pension Plan Investment Board in 2023.

Physicists Revive 1990s Laser Concept To Propose a Next-Generation Atomic Clock

Published

on

Physicists have proposed a new kind of atomic clock based on a revived superradiant laser concept that could produce an extraordinarily stable signal with a linewidth around 100 microhertz, potentially the narrowest ever for an optical laser. “The implications of this result could stretch well beyond timekeeping,” reports Phys.org. “A laser immune to environmental frequency shifts would be a powerful tool in optical interferometry — using interference patterns in light to make ultra-precise measurements.” From the report: In a conventional laser, a mirrored cavity bounces light back and forth between atoms, building up a bright, coherent beam. A superradiant laser works differently: rather than relying on the cavity to maintain coherence, the atoms themselves act as single coordinated emitters, collectively synchronizing their light emission. Following early theoretical ideas emerged in the 1990s, the concept didn’t gain concrete traction until 2008, when researchers at the University of Colorado proposed that superradiant lasers could serve as a new kind of atomic clock.

Atomic clocks work by using laser light to probe a very precise transition in an atom, causing electrons to transition between energy levels at an extraordinarily stable frequency. Because a superradiant laser stores its coherence in the atoms rather than the cavity, its output frequency is far less vulnerable to environmental disturbances like vibrations or temperature fluctuations. Yet although this concept was first demonstrated experimentally in 2012 in a pulsed regime, the influence of heating has so far held superradiant lasers back from their full potential. To keep the laser running continuously as an atomic clock requires, atoms must be constantly replenished with energy. Doing this atom-by-atom delivers random kicks that heat the atomic sample and disrupt the lasing process, confining it to brief pulses rather than a steady beam.

In their study, Reilly’s team considered whether a modification to earlier theoretical concepts could make a continuous laser suitable for an atomic clock. In almost all previous studies, atoms were treated as simple two-level systems: an electron sitting in a ground state, occasionally jumping up to an excited state and back again. The team proposed that the heating problem could be solved by adding one extra ground state to the picture. In a two-level system, if both the pumping (re-energizing) and decay processes happen collectively through the cavity, the mathematics constrains the system in a way that prevents stable, continuous lasing. But with three levels available, pumping and decay can operate on entirely separate transitions, breaking that constraint and allowing the collective approach to work. The findings have been published in the journal Physical Review Letters.

Palantir is reportedly helping the IRS investigate financial crimes

Published

on

Palantir has helped the Internal Revenue Service’s Criminal Investigations office probe a variety of financial crimes in the U.S. for much of the last decade, The Intercept reported.

The IRS has paid the firm $130 million since 2018 to use its data analysis software to pore over financial records for investigative purposes, the outlet reported, citing public records detailing Palantir’s IRS contract that were obtained by the nonprofit watchdog group American Oversight.

It was previously known the IRS was using Palantir’s products, and that the agency sees the software as a way to automate and modernize audits. Last summer, it was also reported that Palantir was assisting DOGE, the “government efficiency” initiative launched by President Trump’s executive order with a project designed to access IRS records. However, the extent of the agency’s use of the company’s tools had not been previously reported.

The software, Palantir’s Lead and Case Analytics platform, is being used to aggregate and analyze data across a variety of federal agencies. The software can find “connections from millions of records with thousands of links” between various databases, and the tool is particularly good at mapping human relationships and communications, according to the outlet.

Earlier this week, American Oversight sued the Trump administration for public records related to numerous federal agencies’ use of Palantir tools, including the IRS. TechCrunch has reached out to Palantir for more information and will update the article if the company responds.
