Bluesky Launches AI App That Lets You Build Your Own Social Feed

Bluesky just introduced Attie, a new AI-powered application that lets users create custom social media feeds using nothing more than plain English. The tool was unveiled by former Bluesky CEO Jay Graber and CTO Paul Frazee at the Atmosphere conference and marks a significant step in bringing artificial intelligence into decentralized social networking.

How Attie Turns Words Into Algorithms

Attie runs on Anthropic's Claude, a large language model that acts as a coding agent inside the app. A large language model, or LLM, is a type of artificial intelligence system trained on massive datasets so it can understand and generate human language. When users describe the kind of feed they want in everyday words, Claude translates that request into working code built on Bluesky's AT Protocol—the open framework that powers the entire platform and all its connected applications.

This means anyone can design a personalized algorithm tailored to their specific interests without writing a single line of code. Users sign in with their existing Atmosphere credentials, and because Bluesky's ecosystem is built on open protocols, Attie can immediately access their activity and preferences across connected apps. The result is a feed that reflects what users actually want to see rather than what a company-controlled algorithm decides to surface.

Beyond Feeds: Vibe-Coding Social Apps

Bluesky's ambitions for Attie stretch well beyond feed customization. The team has confirmed plans to eventually let users vibe-code entire social applications—building tools and experiences for other people using the same conversational approach. Vibe-coding refers to the emerging practice of describing what you want software to do in natural language and letting AI handle all the actual programming behind the scenes. This positions Attie as a stepping stone toward a broader creator platform where non-technical users can shape how social media works from the ground up.

The app is currently limited to Atmosphere conference attendees in a closed beta phase, with broader access available through a waitlist. Bluesky has not announced a specific timeline for a full public launch.

The release places Bluesky in sharp contrast with platforms like X and Meta's Threads, which rely on opaque, company-controlled recommendation systems. By handing feed design to individual users and pairing it with conversational AI, Bluesky is making a bold bet that people want genuine control over what appears in their timelines. If Attie delivers on its promise, it could set a new standard for how social platforms think about user agency and algorithmic transparency.
