Perplexity is continuing the rollout of its AI browser to more users. Comet is now available to download for Android mobile devices from the Google Play Store. Comet initially debuted this summer only to Perplexity's high-rolling subscribers on the $200-a-month Pro plan, but it expanded access to all users last month. It's free on Android as it now is on other platforms, and has many of the same features as the desktop version. The mobile option has access to Perplexity's AI assistant, and it can summarize searches or be interacted with by voice. 

Perplexity has been forthright about its goals of launching a browser as a way to collect customer data so it can more effectively target ads, and it's not the only artificial intelligence company or tech company trying to integrate AI into the browsing experience. These efforts have already drawn complaints from Amazon, particularly around AI in shopping, but they could yield big paydays for scammers.

You probably haven't heard of Read AI. The company has quietly been making a name for itself in the crowded AI space, signing up 50,000 customers daily in recent months. At first glance, Read AI resembles apps like Otter.ai. You can use the software to transcribe and summarize meetings, but it's also more ambitious than that. 

"It's AI on standby," Read AI CEO David Shim explains, adding that the company's vision is to give people a tool that can record, transcribe and analyze nearly every professional conversation they have, no matter where those discussions take place and whether they occur online or in-person. Today, Read AI is taking a major step toward realizing that vision with the release of its new Operator agent (I'll admit, the company could have picked a more original name), and new apps for Windows, macOS and Android. 

Between its own software, including an existing iOS app, and third-party integrations, Read AI users can now connect their accounts to more than 22 other platforms. Some of the more notable inclusions there are Gmail, Outlook, Slack, HubSpot and Notion. More importantly, with Read AI's mobile apps, you can record impromptu in-person meetings; the company has data showing that more than half of professional conversations occur outside of online spaces.   

In any case, no matter where you talk to your colleagues, Operator is there to generate notes and insights. "We don't just look at meetings," Shim says. "We look at topics that are interesting to you.” To that end, Read AI has built a series of in-house multimodal models that look for context beyond what's said during any interaction you record. For example, the company's systems are designed to catch when you enthusiastically answer a question or look away in disinterest, and use that data to decide how the software goes about summarizing your meetings. 

"That context is what enables us to identify what is valuable to you, and make that discoverable," says Shim. One way Read AI will surface those insights is through a feature the company calls Monday Brief. At the start of every week, you'll get a summary of all the calls and conversations you had over the last seven days, with suggestions for follow-up actions you can take.

Now, you might be wondering, like I was, how Read AI hopes to compete in a market where a company like Microsoft is aggressively pushing Copilot on its users. If Shim is worried about the big players, he doesn't show it. "There's a need for an independent third party," he says. "There's always something new coming out. And that ability to be the independent third-party that plugs into different solutions is actually what consumers want and need." To his point, since the launch of Copilot two years ago, Read AI has seen a 20x increase in the daily number of people using its software alongside Microsoft Teams. "We've seen the same thing along those lines for Zoom and Google Meet."   

He believes the company's approach to data privacy is another differentiator. By default, users are opted out of their data being used for training Read AI's future models. Shim also notes the company takes recording disclosure seriously. "You need to notify people that you're [recording] a call, and we put that front and center every single time." 

If you want to try Read AI, the company offers a free plan that includes five meeting transcripts per month. Pricing for its paid subscriptions start at $19.75 per month.    

TikTok is replacing its screen time management page with a Time and Well-being space, which also comes with new wellness features. You can now find an affirmation journal, where you can set your intentions for the day using the 120-plus cards the app provides. You can, say, choose the “grace” card that reminds you to be free of the expectation of others. The card is downloadable on your device, and you can share it with others.

You’ll also find an in-app soothing sound generator that you can use to listen to relaxing audio, such as those featuring the sound of rain, waves and white noise. The sounds stop after a few minutes when the timer ends, so you can play them to induce sleep when you go to bed. TikTok says its users are 14 percent more likely to listen to music to help them relax or go to sleep than non-users. You’ll also find different types of breathing exercises you can do in the new space.

In addition, TikTok is rolling out new well-being missions, expanding the original set it launched in July. These missions, which are particularly designed for teens, will reward you with badges for completing challenges related to balanced digital habits. The new Sleep Hours Mission will award you with a badge if you stay off TikTok at night, while the daily screen time mission will earn you another if you set a screen time limit and manage to stick to it. There’s also a new weekly screen time mission that will prompt you to check your screen time report every week, as well as a well-being ambassador mission that will earn you badges if you invite others to do the missions.

TikTok is the latest social platform to hand users more control over the amount of AI-generated content they see. The app is experimenting with a new setting that will allow users to request to "see less" AI in their "For You" feed.

The new toggle will be available in “the coming weeks” in the app's "manage topics" section that lets people personalize the types of videos more likely to appear in their feed. In a blog post, TikTok says the control is meant to help users "dial things down" if they want to see less AI content in their recommendations. The update follows a similar move from Pinterest, which has faced complaints about AI slop drowning out authentic images on the platform.

TikTok, like most other platforms, has seen an influx of AI-generated content in recent years. The company, which requires users to label such creations, says that there are more than 1.3 billion videos with these labels. At the same time, the company notes that its existing methods for detecting AI content aren't perfect, Currently, TikTok relies on a widely-used watermarking system called Content Credentials that adds metadata to AI-generated content. But these signals can get harder to detect when images or videos are edited in other apps or copied and reshared to other sites, as often happens with viral content. 

To address this, TikTok says that it will also experiment with an additional "invisible watermarking" system that could help it identify and label AI content more reliably. "'Invisible watermarks' add another layer of safeguards with a robust technological 'watermark' that only we can read, making it harder for others to remove," the company explained.
