As clean as your home may be, there are plenty of factors at play that can contribute to the accumulation of pollutants indoors. An air purifier is an easy way to freshen things up and improve the air quality in your home — and one of our favorites, the Levoit Core 400S, is currently 14 percent off. In a limited time deal on Amazon, the Levoit Core 400S in white is down to $190 from its usual price of $220.

The Levoit Core 400S is a standard air purifier in terms of its design, with a cylindrical body that has vents at the top and a simple display that offers touch controls and air quality readings. A color-changing ring at the center of the device surrounding the pollution measurement provides quick information at a glance; it’ll be either blue, green, orange or red depending on the air quality. It has a 360-degree filtration system and is stated to capture over 99.9 percent of pollutants as small as .3 microns, including dust, pollen and pet dander.

The Core 400S is one of our top picks for the best air purifiers you can get this year. It is compatible with Alexa and Google Assistant for voice controls, and can perform automatic purification duties. When running on auto, it’ll adjust its fan speeds based on changes in the surrounding air quality. The smart air purifier also connects to an app, where you can check the air quality reports even if you’re not home. It also has a sleep mode for quieter performance at night, and it’ll dim or turn off the display so you aren’t disturbed by bright lights.

The Levoit Core 400S combines pre-filter, activated carbon and HEPA into a ring-shaped filter that can be replaced for $50. The company claims it can purify an area of 1980 square feet once per hour. It may not have a standout design, but it gets the job done.

An AI chatbot released by the New York City government to help business owners access pertinent information has been spouting falsehoods, at times even misinforming users about actions that are against the law, according to a report from The Markup. The report, which was co-published with the local nonprofit newsrooms Documented and The City, includes numerous examples of inaccuracies in the chatbot’s responses to questions relating to housing policies, workers’ rights and other topics.

Mayor Adams’ administration introduced the chatbot in October as an addition to the MyCity portal, which launched in March 2023 as “a one-stop shop for city services and benefits.” The chatbot, powered by Microsoft’s Azure AI, is aimed at current and aspiring business owners, and was billed as a source of “actionable and trusted information” that comes directly from the city government’s sites. But it is a pilot program, and a disclaimer on the website notes that it “may occasionally produce incorrect, harmful or biased content.”

In The Markup’s tests, the chatbot repeatedly provided incorrect information. In response to the question, “Can I make my store cashless?”, for example, it replied, “Yes, you can make your store cashless in New York City” — despite the fact that New York City banned cashless stores in 2020. The report shows the chatbot also responded incorrectly about whether employers can take their workers’ tips, whether landlords have to accept section 8 vouchers or tenants on rental assistance, and whether businesses have to inform staff of scheduling changes. A housing policy expert that spoke to The Markup called the chatbot “dangerously inaccurate” at its worst.

The city has indicated that the chatbot is still a work in progress. In a statement to The Markup, Leslie Brown, a spokesperson for the NYC Office of Technology and Innovation, said the chatbot “has already provided thousands of people with timely, accurate answers,” but added, “We will continue to focus on upgrading this tool so that we can better support small businesses across the city.” 

AT&T says 7.6 million current customers were affected by a recent leak in which sensitive data was released on the dark web, along with 65.4 million former account holders. TechCrunch first reported on Saturday morning that the company has reset the passcodes of all affected active accounts, and AT&T confirmed the move in an update published on its support page. The data set, which AT&T says “appears to be from 2019 or earlier,” includes names, home addresses, phone numbers, dates of birth and Social Security numbers, according to TechCrunch.

TechCrunch reports that it alerted AT&T about the potential for the leaked data to be used to access customers accounts on Monday, after a security researcher discovered that the records included easily decipherable encrypted passcodes. AT&T has since said that it’s launched an investigation into the issue, but so far “does not have evidence of unauthorized access to its systems resulting in exfiltration of the data set.” The data appeared on the dark web about two weeks ago, according to AT&T.

It comes three years after a hacker known as ShinyHunters claimed in 2021 that they’d obtained the account data of 73 million AT&T customers. AT&T at the time told BleepingComputer that it had not suffered a breach and that samples of information shared by the hacker online did “not appear to have come from our systems.” The company now says that “it is not yet known whether the data in those fields originated from AT&T or one of its vendors.”

AT&T says it is working with cybersecurity experts and will reach out to both current and former account holders who have been affected by the leak. The company also says it will offer credit monitoring to those customers “where applicable.”

X is funding a lawsuit filed by Chloe Happe against her former employer Block, which was founded by Jack Dorsey, the same person who founded the website formerly known as Twitter. In her lawsuit, Happe said Block had wrongfully fired her in retaliation for two posts she made on what she called her "pseudonymous, satirical account" on X while on her personal time. One of the posts made after the October 7 Hamas attacks on Israel referenced refugees fleeing Gaza and and coming to the region of Kurdistan. In another, she used ableist language and a slur against transgender people while referencing the use of a "gender neutral restroom in the office."

Happe repeatedly stressed that she "expressed her political views, opinions, or beliefs in the form of satire." She said she did not mention Block in any post on her anonymous account and that she did not make those posts during her work hours. Happe also said that she "voluntarily deleted" the post on refugees within days of posting. She deleted the post with the slurs on the same day she made it upon seeing that X had limited its visibility. 

But Block still obtained copies of the posts and wouldn't tell her if another employee had complained about it, she argued in her lawsuit, admitting that she initially denied making them out of fear that she could get in trouble. She accused Block of terminating her, without severance, solely because she expressed views the company disagreed with. Happe argued that Block's policies expressly allowed its employees to engage in speech like her post, so it was the company that violated its own rules. Jack Dorsey, the founder of both Block (a financial services company) and Twitter, had publicly endorsed Elon Musk before the latter took over ownership of the social media platform. Last year, though, he changed his tune and criticized Musk, saying "it all went south" after he took over and that he "should have walked away" from the acquisition.

On his account, Elon Musk retweeted X's announcement that it's supporting Happe's lawsuit with the caption: "Supporting your right to freedom of speech." The company had previously funded other lawsuits in the name of "free speech." One of those cases is Gina Carano's lawsuit against Lucasfilm and Disney, which she accused of removing her from The Mandalorian for expressing views that were "not in line with the acceptable narrative of the time." Carano notably questioned the effectiveness of COVID-19 vaccines and added "boop/bop/beep" as her pronouns. She also shared a post on Instagram that compared the treatment of conservatives in America to the treatment of Jews in Nazi-era Germany. 

Happe is asking the court to order her reinstatement as a Block employee. She is also asking for compensatory and punitive damages, including for loss of pay from the time she was terminated. 

US Congressional staff members can no longer use Microsoft's Copilot on their government-issued devices, according to Axios. The publication said it obtained a memo from House Chief Administrative Officer Catherine Szpindor, telling Congress personnel that the AI chatbot is now officially prohibited. Apparently, the Office of Cybersecurity has deemed Copilot to be a risk "due to the threat of leaking House data to non-House approved cloud services." While there's nothing stopping them from using Copilot on their own phones and laptops, it will now be blocked on all Windows devices owned by the Congress. 

Almost a year ago, the Congress also set a strict limit on the use of ChatGPT, which is powered by OpenAI's large language models, just like Copilot. It banned staffers from using the chatbot's free version on House computers, but it allowed them to continue using the paid (ChatGPT Plus) version for research and evaluation due to its tighter privacy controls. More recently, the White House revealed rules federal agencies have to follow when it comes to generative AI, which would ensure that any tool they use "do not endanger the rights and safety" of Americans. 

Microsoft told Axios that it does recognize government users' need for higher security requirements. Last year, it announced a roadmap of tools and services meant for government use, including an Azure OpenAI service for classified workloads and a new version of Microsoft 365's Copilot assistant. The company said that all those tools and services will feature higher levels of security that would make it more suitable for handling sensitive data. Szpindor's office, according to Axios, will evaluate the government version Copilot when it becomes available before deciding if it can be used on House devices. 

LinkedIn is testing a new feed of TikTok-like vertical videos. The feature hasn’t been publicly announced but it’s been spotted by users in recent days and the company confirmed the tests to TechCrunch.

According to a screenshot shared by Instagram employee Jenny Eishingdrelo and a video posted to LinkedIn by influencer marketing exec Austin Null, the new feed will appear in a separate “video” tab in the LinkedIn app. Users will be able to scroll vertically to move between clips, much like TikTok or Instagram Reels.

It’s not the first time the company has hopped on a trendy format. LinkedIn previously experimented with a Stories feature for disappearing posts. That feature lasted less than a year, though the professional network hinted at the time that it wasn’t done with its video experiments, saying it was working “to evolve the Stories format into a reimagined video experience across LinkedIn.”

Presumably, LinkedIn is hoping the feed will showcase content from its ranks of professional creators and thought leaders, many of whom are already posting video to their feeds. However, it’s not clear how many of the site’s users are interested in a dedicated video feed for workplace-related content.

An oddball new app called Palmsy lets you post to a social media network full of adoring followers who only exist in your imagination. Whether used as a journaling app with a fresh twist or a nicotine patch equivalent for social media addiction, Palmsy prevents the real world from ever seeing your “posts,” storing them on-device, offline and private.

Palmsy’s App Store description says it “lets you make little posts for yourself.” And, at its core, that’s all you’re doing. As for why you’d want to do such a thing, people who have trouble with typical journaling or mind-mapping apps may find it a more inspiring framework. Or, if your social posting habit has gotten out of hand (or you want a break from it for any other reason), it could serve as a way to wean yourself off and give you the dopamine hit without sharing anything publicly.

One clever wrinkle from developer Pat Nakajima is that the app imports your contacts to generate fake likes from them. As pointed out by TechCrunch, Nakajima wrote on Threads that nothing leaves your device or is posted to your contacts, the app’s servers or anywhere else. “It’s just pretend,” he clarified.

If seeing fake likes from real contacts feels a bit too weird, a recent update added the ability to limit the number of faux likes your posts get. You can also set caps on how long you receive them, ranging from a few seconds to a few days.

The app is free and iOS-only, including iPhone and iPad variants.

Instagram is working on a feature that would recommend Reels to you and a friend based on videos you've shared with each other and your individual interests. Reverse engineer Alessandro Paluzzi unearthed the feature, which is called Blend. Instagram confirmed to TechCrunch that it's testing Blend internally and it hasn't started trialing it publicly. It may be the case that Blend never sees the light of day, though it's always intriguing to find out about the ideas Instagram is toying with.

The platform hasn't revealed more details about how Blend will work, though the idea seems to be that Instagram users and one of their besties will discover new Reels together instead of one of them finding a video they like and DMing it to the other. It would make sense for Blend to have an indicator that the other person has already seen a particular Reel so that the two people who have access to the feed can start chatting about it. 

TikTok doesn't have a feature along these lines, as TechCrunch notes, so Blend could give Instagram an advantage when it comes to folks who like to check out short-form videos together. As with many of the other features platforms of this ilk introduce, Blend fundamentally seems to be about increasing engagement.

OpenAI just announced that it recently conducted a small-scale preview of a new tool called Voice Engine. This is a voice cloning technology that can mimic any speaker by analyzing a 15-second audio sample. The company says it generates “natural-sounding speech” with “emotive and realistic voices.”

The technology is based on the company’s pre-existing text-to-speech API and it has been in the works since 2022. OpenAI has already been using a version of the toolset to power the preset voices available in the current text-to-speech API and the Read Aloud feature. There are a bunch of samples on the company’s official blog and they sound eerily close to the real thing. I encourage you to give them a listen and imagine the possibilities, both good and bad.

OpenAI says they see this technology being useful for reading assistance, language translation and helping those who suffer from sudden or degenerative speech conditions. The company brought up a Brown University pilot program that helped a patient with speech impairment issues by creating a Voice Engine clone pulled from audio recorded for a school project.

Despite the potential benefits, bad actors would certainly abuse this technology to engage in some serious deepfake tomfoolery, which is already a problem. With this in mind, Voice Engine isn’t quite ready for prime time, as there are serious privacy concerns that must be met before a full rollout.

OpenAI acknowledges that this tech has “serious risks, which are especially top of mind in an election year.” The company says its incorporating feedback from “US and international partners from across government, media, entertainment, education, civil society and beyond” to ensure the product launches with a minimal amount of risk. All preview testers agreed to OpenAI’s usage policies, which ban the impersonation of another individual without consent or legal right.

Additionally, anybody using the tech will have to disclose to their audience that the voices are AI-generated. OpenAI implemented safety measures, like watermarking to trace the origin of any audio and “proactive monitoring” of how the system is being used. When the product officially rolls out there will be a “no-go voice list” that detects and prevents AI-generated speakers that are too similar to prominent figures.

As for when that rollout will occur, OpenAI remains tight-lipped. TechCrunch uncovered some potential pricing data and it looks like it will undercut competitors in the space like ElevenLabs. Voice Engine could cost $15 per one million characters, which works out to around 162,500 words. This is about the length of Stephen King’s The Shining. It certainly sounds like a budget-friendly way to get an audiobook done. The marketing materials also make reference to an “HD” version that costs twice as much, but the company hasn’t detailed how that will work.

OpenAI has been making big moves this week. It just announced another partnership with its bestie Microsoft to build an AI-based supercomputer called “Stargate.” The project will reportedly cost a whopping $100 billion, according to The Information.

X is working on features that will allow admins of “Communities,” the platform’s tool for subreddit-like groups, to designate the spaces as containing “adult content.” The change was confirmed by an engineer at X amid reports that the Elon Musk-owned company was working on enabling NSFW groups.

In a post on X, engineer Dong Wook Chung noted that “soon” NSFW content would be automatically filtered in the app’s Communities feature. “Admins can now set 'Adult content' in Settings to avoid auto-filtering of the content,” Chung said.

As Bloomberg reported, researchers had previously spotted clues that X planned to enable settings for “adult-sensitive” content. X permits users to share nudity and other “graphic” content, but doesn’t allow it to appear in certain parts of the app, like profile photos and cover images for Communities.

X’s Communities feature predates Musk’s takeover of the company. Twitter began experimenting with the idea in 2021, saying it would provide “a more intimate space for conversations” on the platform. Though Twitter never publicly discussed enabling NSFW features for Communities, the app allowed adult content, unlike most of its social media peers. The company reportedly looked into creating an OnlyFans competitor with its creator subscription product in 2022. The plan was eventually scrapped, according to the Platformer newsletter, due to concerns it would “worsen” the company’s problems with illegal child exploitation content.

It’s not clear if X’s current leadership has addressed those concerns. In a separate post, Chung, the X engineer, stated that the new filtering settings “is about making Communities safer for everyone by automatically filtering out” adult content. “Only users who have specified their age will be able to search Communities with NSFW content.” 

X didn’t immediately respond to a request for comment.
