NotebookLM, the Google research tool that gained notoriety for its uncanny AI-generated podcasts, is getting an official app on May 20, 2025. You can pre-register for the Android or iOS version of the app right now and have it automatically downloaded to your device on May 20, the first day of Google I/O 2025. 

Based on the listings in the Play Store and App Store, Google seems intent on keeping all of the core functionality of the web version of NotebookLM intact for its mobile debut. You can upload a variety of different sources (PDFs, website URLs, YouTube videos and copied text) and have NotebookLM, powered by Gemini, do stuff with them. That could be answering specific questions, generating study guides or creating an Audio Overview, the previously-mentioned "podcasts."

Google

NotebookLM started life as Project Tailwind back at I/O 2023 and has gradually transitioned from research project to real product over time. The service officially launched as NotebookLM in December 2023 and gained Audio Overviews in September 2024. As of April 2025, NotebookLM is now offered in more than 50 languages. Getting an actual app release is the best sign yet the service is here to stay.

Critical to its sucess, NotebookLM makes more sense as a tool you can trust than basically any other Gemini product. The service's output is grounded in documents and sources you choose. That means Google's AI is less likely to hallucinate because it's quoting a research study directly, and it's easier to double check its answers because you can view the source directly in NotebookLM.

Google has already signaled that I/O 2025 will be Gemini-focused by breaking out Android announcements into their own stream, so there's a good chance NotebookLM won't be the only AI product getting some love on May 20. It remains to be seen whether Google has any ideas as cogent as "an AI that helps you digest long PDFs," though.

Apple has updated its App Store guidelines to comply with the orders of a California court, which required the company to immediately stop collecting commissions on purchases that weren't paid through the App Store. As noticed by 9to5Mac, the most prominent change in the guidelines states that there are now no prohibitions on "buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase," as long as it's for an app on the US storefront. Further, developers don't have to request for an entitlement from Apple to be able to offer external link purchases on apps for the United States storefront anymore. 

In the section stating that certain applications, such as reader apps and apps that sell goods and services, cannot encourage users to opt for third-party purchasing methods in-app, Apple added that the prohibition doesn't apply to apps on the US store. "The App Review Guidelines have been updated for compliance with a United States court decision regarding buttons, external links, and other calls to action in apps," Apple said in a statement.

These changes come as a result of a recent ruling by Judge Yvonne Gonzalez Rogers, who found that Apple violated her 2021 ruling for Epic Games' lawsuit against Apple. Back then, she ordered Apple to allow developers to direct users to other payment systems that would let them avoid paying the company a 30 percent cut.

However, Apple still took a 27 percent cut from external purchases, prompting Epic Games to accuse the company of non-compliance in a new legal filing last year. Apple also showed users a "scare screen" when they try to make external purchases, discouraging them from using third-party payment systems. In addition to ordering Apple to stop collecting fees from purchases made outside the App Store, Gonzalez Rogers also prohibited Apple from creating rules that would prevent developers from presenting customers with buttons and links for external payments

In response, Epic chief Tim Sweeney announced that Fortnite will be coming back to iOS next week. He also said that the video game company will bring back Fortnite on iOS for everyone and will drop all litigation regarding the issue if Apple adopts the no-commission policy worldwide, but that doesn't seem to be the case for now. Other companies are now also looking to roll out updates that would allow them to bypass Apple's commission for external payments. One of them is Spotify, which announced that it had already submitted an update that would allow customers in the US to pay outside the App Store. 

This week Meta held its first-ever AI dev conference, LlamaCon, focused on the development of its Llama generative AI model. But while there was plenty of hype, not much happened, besides the launch of the Meta AI app and a new Llama API. In this episode, Engadget Senior Reporter Karissa Bell joins us to talk about her thoughts on LlamaCon after attending in person. After just announcing its latest Llama models a few weeks ago, it was as if Meta didn't have much else to say.

If you've been thinking about upgrading your old Apple Watch, or you're keen on picking one up for the first time, take note: The Apple Watch Series 10 is back down to $299 in a few colorways at Amazon and Best Buy. We've seen this deal a few times in recent months; nevertheless, it matches the wearable's lowest price to date.

This price applies to the 42mm GPS version, but the GPS + cellular model is also on sale for $110 off, bringing it down to $389 in a handful of color options. If you want something larger, meanwhile, the 46mm GPS model is $100 off Apple's list price and down to a low of $329 as well. Considering the Apple Watch is usually only updated once a year alongside the iPhone in September, these are decent deals to snag now while the Series 10 will remain the flagship smartwatch in Apple's lineup for a few more months.

The Apple Watch Series 10 is our pick for the best smartwatch overall, though note that you'll need a compatible iPhone to use it. We gave the wearable a score of 90 in our review.

Admittedly, this is a relatively iterative upgrade. If you have an Apple Watch Series 8 or 9, the upgrade is probably not worth it. But if you're an Apple Watch newcomer or you're upgrading from an older model, this is generally the one to go for.

The Series 10 has a larger screen than its predecessor, which makes it easier to see notifications and such. The thinner frame looks nicer too. However, while the Apple Watch Series 10 is great for fitness and wellness tracking, it's a bit disappointing that the device lacks the blood oxygen feature seen in earlier models (though Apple had little choice but to nix that here).

A Snapchat redesign test appears to have stalled after power users seemingly disliked the "simplified" layout.

The new version of Snapchat intended "to help new and casual users" navigate the app, according to Snap’s Q1 investor letter, released on April 29. As reported by TechCrunch, the overhauled app removed the Snap Map and Stories tabs. A proposed new three-tab navigation bar focused on chat, the camera and Spotlight (Snapchat’s answer to TikTok.) The report doesn’t specify how long the testing phase went on for or how widespread it was.

For now at least, Snap is seemingly reconsidering. "Our most engaged Snapchatters consistently demonstrated a preference for a five-tab layout," the company wrote in that same investor letter. While it does not specifically say it's ending tests of the simplified version, Snap notes it has "begun testing a refined five-tab interface that combines the best of both approaches." Engadget reached out to Snap for comment on if this layout is no longer being deployed to users. We’ll update this article if we receive a response.

Snap has a pretty rough track record where redesigns are concerned. In 2017 the company tried to reorient its flagship app around separating friend-related posts from media content; in the year that followed, Snapchat lost three million daily users in the space of three months. At that time there were also well-documented issues with the Android version of the app.

The latest earnings report revealed that Snap lost one million users in North America in Q1, down to 99 million from 100 million in the previous quarter. Despite this, the global Snapchat community grew to 460 million in Q1, an increase of 7 million daily active users quarter-over-quarter.

Meta didn't wait for Tuesday's LlamaCon keynote to unveil its first big AI announcement of the week. The company launched a standalone app that competes with ChatGPT, Gemini, Claude and other multimodal AI chatbots. Sticking to the company’s roots, the app also includes a social feed and the ability to draw on info from your profile and posts you’ve shared.

The Meta AI app offers similar features to rival chatbots, including text and voice chats, live web access and the ability to generate and edit images. But it also includes a Discover feed that (for better or worse) adds a social element to your AI queries. The company describes it as "a place to share and explore how others are using AI." It highlights the prompts that others share and lets you "remix them to make them your own."

Meta stresses that none of your private chats will post to others' feeds unless you explicitly choose to share them.

Meta

For users in the US and Canada, Meta AI can personalize its answers based on data you've shared with Meta products. This includes info like your social profile and content you like or engage with. The company says linking your Facebook and Instagram accounts to the same Meta AI account will provide "an even stronger personalized experience." If you don't want that, this might be a good time to check your privacy settings.

The app has a live conversation mode for users in the US, Canada, Australia and New Zealand. Much like a similar feature in ChatGPT and Gemini, Meta’s version lets you and the AI assistant listen and speak simultaneously, with a natural flow that should feel more like a real conversation. However, Meta only describes it as a demo that provides "a glimpse into the future," suggesting it's still in an early stage. This mode also doesn't offer live web access.

Meta

The Meta AI web version includes the app's new features, including voice interactions and the Discover feed. This version has a few differences, including enhanced image generation (more presets and new editing modes for style, mood, lighting and colors). The web version also lets you test a rich document editor (in some countries) that can spit out text- and image-rich docs to export as PDFs.

The app has merged with the Meta View companion app for the company's Ray-Ban glasses collab. The company says it will include a handoff feature that lets you start a conversation on the glasses and then access it in your history tab on the app or web. After installing the update, you can manage your glasses in the Meta AI app's Devices tab.

You can download the new Meta AI app from the App Store and Google Play.

Google I/O is where we learn about many major features and updates that are coming to the company’s ecosystem, including on the Android front. The company is doing something a little different this year. Just ahead of I/O, it will provide a deep dive into the future of Android with a special edition of The Android Show.

This is the first time that Google has held such a showcase before I/O. The company says that people have been asking for more ways to learn about how the Android experience is changing and giving the ecosystem its own spotlight ahead of the main event is one way to do that. 

Google says it has “so many new things to share" regarding Android, hence this edition of The Android Show (a series that the company has been running for developers on YouTube for a while). The presentation will feature Android Ecosystem president Sameer Samat. Android will still be featured at I/O, where Google is promising to reveal “even more special announcements and surprises.” Multiple Android keynotes are scheduled for the event.

The Android Show: I/O Edition will air on May 13 at 1PM ET. Google I/O takes place a week later, starting on May 20. As ever, we’ll bring you all the important news and updates you need to know from the event right here on Engadget.

Perplexity has rolled out an update for its iOS app, giving iPhone users access to its AI voice assistant that was initially released for Android users earlier this year. Its voice assistant can perform tasks for the user by browsing the web or accessing other apps for them. If they ask the assistant to find them a table for a specific restaurant, for instance, Perplexity can launch the OpenTable app with the number of people, the date and the time already filled out. The user still has to perform the final action and book a reservation, but it's already laid out for them — all they have to do is click the button. 

Users can also ask the assistant to draft emails for them for specific contacts, which they'll have to send themselves, and create reminders for them on the calendar. They can ask it to recommend them spots they could visit, such as restaurants serving food they want to eat, and Perplexity will mark locations on the map. Of course, they can ask the assistant to do web searches for them, such as finding specific videos that Perplexity can open on the YouTube app. 

As The Verge notes, Perplexity's voice assistant works on older iPhones, unlike Apple Intelligence that only works on the company's more recent models. The iOS assistant also doesn't have the capability to look at the world for the user and tell them what they're seeing yet, though the feature is already available on Android and could make its way to iPhones in the future.

Earlier this year, right as TikTok and other ByteDance apps were temporarily pulled from Apple and Google’s app stores, Meta announced that it was working on a new video editing app tailored to Instagram creators. That app, called Edits, is now finally rolling out as Meta continues to try to leverage the uncertainty surrounding TikTok’s future to draw more creators to its apps.

As previewed in its earlier app store listings, Edits promises much more advanced editing tools than what’s been available in Meta’s apps. The in-app camera allows creators to capture up to 10 minutes of video and publish to Instagram in “enhanced quality.” It also features popular editing effects like green screen and Instagram’s extensive music catalog.

In keeping with Meta’s current focus on AI, Edits comes with a couple AI-powered features as well. The “animate” feature allows users to create a video from a static image, while “cutouts” enables video makers to “isolate specific people or objects with precision tracking.” And unlike ByteDance’s popular editor CapCut, Edits doesn’t export videos with a watermark of any kind (Instagram downranks videos with visible watermarks).

While Edits is launching months after CapCut came back online in the US, Meta is adding some Instagram-specific features to lure Reels creators. This includes in-app post analytics, as well as the ability to import audio tracks they’ve previously saved in the app. And it sounds like Instagram creators can look forward to more specialized features in the future. In a blog post, the company notes that the current version of the app is merely “the first step” for Edits, and that it plans to collaborate with creators on more functionality going forward.

Edits is out now in the App Store and Google Play.
