Bluesky Unveils ‘Attie’: AI App That Lets Users Build Custom Feeds With Simple Prompts

Bluesky has introduced a new standalone AI application called Attie, marking a significant step in its push toward more customizable and user-controlled social experiences. The app allows users to create personalized content feeds and even experimental social “mini-apps” simply by describing what they want in natural language.

The announcement was made during Bluesky’s Atmosphere conference, where the company outlined its broader vision of turning social media into an open, programmable ecosystem rather than a fixed platform controlled by opaque algorithms. Attie represents the first major product to emerge from that direction.

What Attie is and how it works

Attie is not a feature inside the Bluesky app. It is a separate product built on the same open infrastructure known as the AT Protocol, which underpins Bluesky’s decentralized network.

At its core, Attie functions as an AI assistant powered by Anthropic’s Claude model. Instead of manually configuring filters or writing code, users interact with the system conversationally. They can type requests such as “show posts about mythology and traditional music” or “find builders working on open AI infrastructure,” and the system generates a custom feed based on that description.

The experience is designed to feel less like software configuration and more like a dialogue. Users describe intent, and the system translates that into a working algorithm that curates content accordingly.

From feed creation to programmable social tools

While custom feeds are the immediate focus, Attie’s scope extends beyond simple content filtering. The system can recommend posts to engage with, learn from user behavior across the AT Protocol ecosystem, and refine feeds over time based on interaction patterns.

Because Bluesky’s ecosystem shares data across applications built on the same protocol, Attie can draw from a broader social graph rather than being limited to a single app’s dataset. This allows for deeper personalization and more context-aware recommendations.

In its current form, feeds created in Attie remain within the app initially. However, Bluesky plans to integrate them across its main platform and other AT Protocol-based applications as development progresses.

Key capabilities shaping the product

Why Bluesky is moving in this direction

Attie reflects a broader strategic shift for Bluesky. Instead of competing purely as another social media platform, the company is positioning itself as infrastructure for customizable social experiences.

Executives have framed this move as a way to give users control over the algorithms that shape their feeds. Rather than relying on a single centralized ranking system, users can define their own logic for how content is surfaced.

This approach also encourages developers and creators to build on the ecosystem. By lowering the barrier to creating feeds and tools, Bluesky aims to expand participation within its network and move toward a more open, modular social layer.

Launch status and rollout plans

Attie is currently in an early access phase, with initial testing limited to attendees of the Atmosphere conference. These users are serving as the first group of beta testers, providing feedback on both functionality and usability.

A broader rollout is expected in stages. Over time, feeds created through Attie are likely to become accessible within the main Bluesky app and other compatible platforms built on the AT Protocol.

What this means for the future of social platforms

Attie introduces a different model for how social media could function. Instead of fixed interfaces and centrally controlled feeds, it moves toward a system where users actively shape their own experience through AI-assisted tools.

The concept is still early, and its success will depend on how well it scales beyond experimentation. But the direction is clear. Bluesky is not just building a platform. It is attempting to redefine how social systems are created, controlled, and experienced.
