Bluesky's Attie now builds small social apps from a text prompt

What Bluesky launched on 15 October

Attie, the experimental AI app built by the team behind Bluesky, announced a site builder in a thread on Bluesky at 18:12 UTC on 15 October 2026. 'Starting today, Attie users can build small social pages like an AMA, a guestbook, or a survey your friends will argue about for a week,' the post said, adding that the team had made a few examples and inviting people to make a better one and share it.

Bluesky chief executive Toni Schneider presented the feature in an interview at TechCrunch Disrupt 2026 the same day. 'We're adding a feature to our Attie product that allows you to build sites and social experiences again for a group of people,' he told TechCrunch. 'So think of it as ... social vibe coding or vibe coding for your community.'

His point is that most AI app builders are made for one person working alone. 'Vibe coding today is kind of a single-user, solo experience,' Schneider said. 'And what I want to be able to do is build together or build for a group of people, and that's what this product does.'

What the Attie site builder makes

The Attie homepage now opens with 'Make something for the open social web' and the line 'Describe a small social app and I'll build it with you.' It lists starter ideas: a poll, an event, a guestbook, a game, an ask-me-anything page, a leaderboard, a journal, a landing page, a survey, a dashboard, and an 'explain the joke' page that tells the story behind a reference. It promises three things: no code is needed, sites are social from day one because friends can sign in with Bluesky to vote, RSVP or sign, and every site gets its own shareable link.

Attie's launch thread showed three starter sites. Flappy Butterfly is a Flappy Bird-style game where you dodge speech bubbles labelled as bad takes and collect likes. A like is a point, a good post is worth three, a block clears a hazard, a mute gives you ghost mode, and a shield absorbs one hit. Its leaderboard says every score was replayed and verified by the server. The second is a poster-persona quiz: you answer ten posting scenarios, then sign in so it can read your last 100 posts and plot who you think you are against who your posts say you are on a 3x3 alignment chart. The third is an AMA site that takes questions, anonymously if you like, and posts selected answers back to Bluesky.

The Verge's Jay Peters tried it and said a simple poll about Pokemon Red and Pokemon Blue took a few minutes to generate. He found the showcase apps, which also include a drum machine and an idle clicker about a celery man, to be 'pretty lightweight novelties', though he liked the drum machine. Each site carries attribution to its maker at the bottom of the page.

How the sites connect to Bluesky and ATProto

What separates Attie from general-purpose app builders is where the apps live. TechCrunch reports that the sites, games and quizzes sit on the AT Protocol, or ATProto, the open protocol behind Bluesky and the wider set of apps its community calls the Atmosphere. When people build with Attie they are connected to their ATProto identity, and Attie suggests things to make based on their public Bluesky profile.

Early users found that suggestion feature hard to miss. In posts Attie reshared on 15 October, one user said it had learned he was moving to Oakland in two days and liked walking, so it built him a site to track his walks; another said he liked how it used his publicly available activity to suggest something he might actually want to make. Because Bluesky posts are public by design, an app like this can read a lot about you before you type a word.

Bluesky chief operating officer Rose Wang told TechCrunch that people can bring their own AI model or use open-weight options to build, and that the finished sites can reach Bluesky's audience. 'Everybody is building ... But the big question is: Who's using the thing you're building, because we haven't solved that problem with distribution,' she said. 'What makes Attie so interesting is that it comes with the Bluesky distribution, so it doesn't stand alone.'

From custom feeds to social vibe coding

Attie first appeared on 28 March 2026, when TechCrunch described it as a stand-alone AI assistant for designing your own algorithm and building custom feeds, offered first as a private beta. It was the first product from former chief executive Jay Graber's new team after she stepped back to focus on building, and TechCrunch reported that it ran on Anthropic's Claude under the hood. 'We think AI should serve people, not platforms,' Graber said at the time.

Even then, the stated plan was to let users eventually vibe-code their own social apps and build tools for other people. The 15 October builder is that plan arriving. In between, Attie's account posted a string of smaller additions: turning 'quest' results into lists and starter packs in August, expanding the countries with access, and in October a way to catch up on your 'Bluesky lore' and share it as a card. The idea of steering a feed in your own words has since spread, with Facebook's Your algorithm controls arriving this week.

Bluesky users push back on the AI feature

The launch thread drew a hostile response. Of the replies we read on 16 October, most objected to AI on Bluesky. The most-liked reply simply said 'Ew ai'. The next, with about 160 likes, complained that Bluesky could repost the launch but not add an edit button. Another, with about 150, said: 'Many of us left X for here because of Ai BS, and because artists wanted to share their art without Ai scraping it.' Others asked why the company was building AI tools before features users have requested, such as images in direct messages.

That reaction is not new for Attie, but it shows the tension in Bluesky's plan. Many people moved to the network partly to get away from AI-heavy feeds elsewhere, while the company sees AI tools as a way to make building on its open protocol accessible to people who cannot code. Attie is a separate app from Bluesky, which helps a little: nobody has to use it.

Why Bluesky is betting on small social apps

Bluesky has about 47 million registered users, according to the figure TechCrunch cites, but has seen engagement fall as some people who tried it went back to X. Schneider, a former Automattic chief executive, is betting on developers and communities to revive activity, helped by the protocol's coming support for private data, which he said has been developers' biggest request. Private data is in alpha testing and due to roll out by the end of the year, he told TechCrunch.

'There should be lots and lots of these fun, small social experiences for your friends,' Schneider said. 'We don't all have to go communicate with the entire world all the time.' It fits a broader shift toward personal, throwaway software, the same idea behind Google Play's private vibe-coded apps and tools like VoidZero's Void for hosting vibe-coded apps. Attie's twist is that the audience comes built in.

What is still unclear

Attie's site still describes the service as early access, and neither the launch thread nor the coverage says whether it will cost money; when Attie launched in March, TechCrunch reported the team had not decided whether it would eventually charge. Bluesky has not published a blog post or documentation for the builder, so the details here come from Attie's thread and site and from the interviews at Disrupt.

Open questions include which models the builder uses by default now that users can bring their own, how much a site can read from a visitor's account after they sign in, who moderates the sites, and how long attie.site pages stay up. AI Lookout has not built a site with Attie.
