Bluesky Launches Attie AI — An App to Build Your Own Social Feed

Bluesky has launched a new app called Attie, an AI-powered assistant designed to let users build their own custom social media feeds. The new app, which was unveiled at the company's Atmosphere conference, represents a significant step in Bluesky's strategy to differentiate itself through user control and its underlying open protocol rather than just as a direct competitor to X or Threads.

The app leverages Anthropic's Claude AI model to translate natural language prompts into functional content filters, according to a report from The Verge. This allows a user to, for example, request a feed of posts about a specific topic without negative sentiment, and Attie will construct the necessary logic. Both The Verge and TechCrunch confirm that Attie is built on the AT Protocol (atproto), the foundational technology that underpins Bluesky's decentralized network.

From Protocol Promise to AI Product

Bluesky’s core pitch has always been about the protocol. The idea is that a composable, open standard for social networking allows for a marketplace of different apps, clients, and algorithms. Until now, creating a custom feed on the AT Protocol required technical skill. Attie is the company’s first major effort to abstract that complexity away.

Former CEO Jay Graber and CTO Paul Frazee presented the app, positioning it as a tool for building your own algorithm. As TechCrunch notes, Attie leans into AI to make the protocol’s power accessible. Instead of writing code, users can simply describe the kind of content they want to see. This lowers the barrier to entry for algorithmic customization, moving it from a developer-centric feature to a consumer-facing product.

A Bet on Algorithmic Choice

This move places Bluesky in direct opposition to the model used by incumbent social media giants. Platforms like Meta's Facebook and Instagram, or ByteDance's TikTok, rely on monolithic, opaque algorithms designed to maximize engagement and ad revenue. Their inner workings are secret and their control is absolute. Bluesky is betting that a growing segment of users wants transparency and choice.

This suggests a broader strategy to win the platform wars not by building a better timeline, but by providing the tools for users to build their own. Attie is the most visible productization of that philosophy to date. By using a third-party model like Anthropic's Claude, Bluesky also signals its focus is on the protocol and user experience layer, not on competing in the foundational model arms race. The pattern indicates a focus on leveraging its unique structural advantage—the protocol itself—rather than trying to out-muscle competitors on features alone. The real test will be whether mainstream users find the prospect of curating their own algorithm compelling enough to switch, or if the convenience of a single, centrally-managed feed remains dominant.
