Bluesky team launched Attie — an AI assistant for creating your own feed algorithm

The Bluesky team has announced Attie — an AI application that allows every user to build a personalized feed algorithm in natural language, without writing a single line of code. At the Atmosphere conference, dedicated to the AT Protocol ecosystem, former Bluesky CEO Jay Graber and technical director Paul Frazee unveiled Attie. The application runs on Anthropic's Claude model and is built on top of the open atproto protocol — the same one that forms the foundation of the entire Bluesky ecosystem and ensures its decentralized architecture.

The idea is simple, but potentially transformative. A user writes a query in plain language — for example, "Show me posts about folklore, mythology and traditional music, especially Celtic traditions" — and Attie creates a separate custom feed for that request. No code, no manual configuration: it's enough to explain in your own words what interests you, and the algorithm assembles itself.

This is a fundamentally different approach to personalization than what we're used to. Most social networks operate with closed algorithms that decide what to show based on behavioral data — views, likes, screen time. The user remains a passive consumer: content is selected based on past actions, not explicitly stated preferences.

Attie reverses this logic: you tell the system what you need. Bluesky has bet on transparency from the start. The AT Protocol is open, and custom feeds have long been one of the platform's key features — technically proficient users have been able to create their own algorithms and share them.

Attie removes the final barrier: now anyone who can articulate their thoughts in text can create a personalized algorithm. Initially, custom feeds will be available only within Attie's standalone application. However, the team intends to gradually integrate them into the main Bluesky client and other applications built on atproto.

This means that the entire ecosystem built on the open protocol — not just Bluesky itself — will be able to use feeds created by users. The choice of Claude from Anthropic as the engine is no accident. The company is actively developing tools for developers embedding AI in their products, and Claude demonstrates high-quality performance with nuanced queries.

This is exactly what's needed to correctly interpret a description like "posts about Celtic music" and not confuse it with similar but irrelevant content. Attie emerges against the backdrop of growing demand for algorithmic transparency. After years of criticism directed at the recommendation systems of Twitter/X, TikTok and Instagram, users increasingly want to understand why they're shown particular content.

Regulators in the EU already require major platforms to disclose their algorithmic logic. Bluesky occupies a unique position: here, transparency is not an exception mandated by regulators, but an architectural principle from day one. If open AI-based algorithms take root as a norm in the atproto ecosystem, it could change the standard of what users expect from social networks overall — and create pressure on closed platforms.
