The latest app from the team behind Bluesky is AT, an AI assistant that lets you create your own algorithms. At the Atmosphere conference, Bluesky’s former CEO, Jay Graber, and CTO Paul Frazee unveiled AT, which is powered by Anthropic’s cloud and built on top of Bluesky’s underlying AT protocol (ATProtocol).
Etsy allows users to create custom feeds using natural language. For example, you might ask for “posts about folklore, mythology, and traditional music, especially Celtic traditions.” To begin with, these custom feeds will be limited to a standalone AT app. But the plan is to make them available in BlueSky and other AtProto apps.
But this is just the beginning. Users will finally be able to use AT to vibe code their own apps on top of ATProto. In a blog post, Graber said:
We built the AT protocol so that anyone could build any app they could imagine on top of it, but until recently “anyone” really meant “anyone who can code.” Agent coding tools change that. For the first time, an open protocol can truly be open to everyone. It is increasingly possible to personalize software without any coding experience. Atmosphere is an open data layer with a clearly defined schema for applications, making it uniquely suited for building coding agents.
AT is currently in closed beta. But you can join the waiting list by visiting attie.ai.
