Former Bluesky CEO Jay Graber and CTO Paul Frazee unveiled Attie at the Atmosphere conference, an AI assistant built on Anthropic's Claude that lets users create custom social media feeds through natural language prompts. Users can request feeds like "posts about folklore, mythology, and traditional music, especially Celtic traditions" without writing code. The tool operates on Bluesky's AT Protocol and is currently in closed beta, with a waitlist available at attie.ai.

This represents a significant shift in how social platforms could work. While algorithmic feed customization isn't new, Attie's promise extends beyond simple filtering to "vibe coding" entire applications on the AT Protocol. Graber argues this democratizes app development on open protocols, claiming "anyone who can code" previously limited AT Protocol development, but AI agents change that equation. The move positions Bluesky's infrastructure as more accessible than traditional social platforms.

The timing is telling — as X/Twitter becomes increasingly unpredictable and Meta tightens algorithmic control, Bluesky is betting on user agency. But the real test isn't whether people can describe their ideal feed in English; it's whether Attie can actually build functional, performant applications from those descriptions. Custom feeds are table stakes compared to generating full social apps, and that capability remains theoretical.

For developers, this could be either a democratization tool or another AI coding assistant with limited real-world utility. The AT Protocol's defined schema might make it more viable for AI generation than general-purpose coding, but we've seen plenty of "code with natural language" promises fall short of production requirements. The proof will be in what people actually build with Attie, not what they can imagine describing to it.
