Bluesky unveiled Attie, a Claude-powered AI app that lets users create custom social feeds and algorithms via natural language, debuted at the Atmosphere conference.
Bluesky's former CEO Jay Graber and CTO Paul Frazee unveiled Attie at the Atmosphere conference — a standalone AI app powered by Anthropic's Claude that lets users build custom feeds, design algorithms, and eventually vibe-code their own apps on the AT Protocol. It's the first product from Graber's new innovation team, separate from the main Bluesky app. Initial beta access is limited to Atmosphere conference attendees, with broader rollout expected later. The app uses atproto's open data layer, meaning Attie can immediately understand a user's interests and history without onboarding friction.
Attie signals that atproto is evolving from a social protocol into a programmable, agent-accessible data layer. Claude is being used not just for chat but for feed curation logic and eventually app generation — meaning agentic access to open social graph data is the new primitive. If you're building on atproto, this is the first major third-party surface where AI-generated apps can natively plug into a shared user identity and data layer without OAuth friction.
Pull the atproto Lexicon schema this week and prototype a Claude-powered feed generator that filters posts by topic — this positions you as an ecosystem builder before Attie's public launch crowds the space.
