The latest app from the team behind Bluesky is Attie, an AI assistant that lets you build your own algorithm. At the Atmosphere conference, Bluesky’s former CEO, Jay Graber, and CTO Paul Frazee, unveiled Attie, which is powered by Anthropic’s Claude and built on top of Bluesky’s underlying AT Protocol (atproto).
Attie allows users to create custom feeds using natural language. For example, you could ask for “posts about folklore, mythology, and traditional music, especially Celtic traditions.” To start these custom feeds will be confined to a standalone Attie app. But the plan is to make them available in Bluesky and other atproto apps.
But that’s just the start. Users will eventually be able to use Attie to vibe code their own apps on top atproto. In a blog post, Graber said:
We built the AT Protocol so anyone could build any app they imagine on top of it, but until recently “anyone” really meant “anyone who can code.” Agentic coding tools change that. For the first time, an open protocol can be genuinely open to everyone. It’s increasingly possible to personalize software with no coding experience at all. The Atmosphere is an open data layer with a clearly defined schema for applications, which makes it uniquely well-suited for coding agents to build on.
For now Attie is in a closed beta. But you can join the waiting list by heading to attie.ai.
