Bluesky, the decentralised social network with 43.4 million users, has unveiled a standalone AI app called Attie that allows anyone to design custom feeds and curate their own social experience without writing code.
The app was presented publicly for the first time at the Atmosphere conference over the weekend by Jay Graber, Bluesky's former chief executive and now chief innovation officer, and chief technology officer Paul Frazee.
Attie runs on Anthropic's Claude and is built on top of atproto, the AT Protocol that underpins Bluesky and the broader Atmosphere ecosystem of apps.
Users sign in with their Atmosphere login and can instruct the app in plain language to build personalised feeds, surface posts they are likely to enjoy, or filter content to their preferences.
Because atproto is an open system that shares data across apps, Attie can immediately draw on a user's existing activity and interests without requiring manual setup.
Interim chief executive Toni Schneider told TechCrunch the app is "the first standalone product built by Jay's new team" and is distinct from features Bluesky has previously launched within its main app.
Graber stepped back from the chief executive role to focus on building, saying she wanted more time to create rather than operate the company.
"We think AI should serve people, not platforms," Graber said at the launch, arguing that major social platforms currently use AI to maximise time spent on their apps and harvest data rather than to benefit users.
At launch, Attie can be used to build and view custom feeds, which will also become available inside Bluesky or any other atproto app; longer-term plans include allowing users to vibe-code their own social apps and build tools for others.
Bluesky separately confirmed it closed a $100 million funding round last year, giving the company more than three years of runway.
Schneider said monetisation of Attie has not yet been decided, with subscriptions and hosting services among the options under consideration, though he ruled out any cryptocurrency integration despite the presence of crypto investors among Bluesky's backers.
