Bluesky leans into AI with Attie, an app for building custom feeds

In a world dominated by algorithms whose workings no one fully understands, Bluesky has decided to hand the reins over to the users. Instead of passively consuming what a black box feeds them, decentralized social media enthusiasts are receiving a tool that redefines the concept of content curation. During the Atmosphere conference, the team responsible for developing the atproto protocol presented Attie – an experimental application that utilizes advanced artificial intelligence to build personalized information ecosystems.

This is not just another Twitter clone or a simple skin for an existing interface. Attie is an AI assistant that allows you to design your own algorithms and create Custom Feeds without having to write a single line of code. The project is led by key figures in the Bluesky structure: Jay Graber, former CEO and current Chief Innovation Officer, and Paul Frazee, the platform's CTO. Their vision assumes that the user should not be the product of the algorithm, but its architect.

Architecture based on the Claude model

At the heart of Attie is technology provided by Anthropic. The application uses the Claude model as the driving engine for an AI agent capable of interpreting natural user queries and translating them into specific filters and data structures within the AT Protocol. As a result, the process of creating your own content stream resembles a conversation with an expert rather than tedious configuration of technical parameters.

The use of the Claude model is not accidental. This choice emphasizes the pursuit of high precision in contextual reasoning, which is crucial for real-time post selection. Attie acts as an intermediary layer that searches the decentralized network and extracts exactly what the user expects, based on a semantic understanding of the topic rather than just simple keywords or hashtags.

• Agentic Social App: The application acts proactively, suggesting improvements in the structure of displayed content.
• Integration with atproto: Full utilization of the open standard, guaranteeing data portability and the absence of lock-ins typical of closed platforms.
• Vibe-coding: The ability to build custom digital experiences by describing the "vibe" or aesthetic that a given feed should represent.

Democratization of algorithms and the end of the dictatorship of trends

Traditional social media relies on algorithms optimized for time spent in the app (engagement), which often leads to polarization and the promotion of sensationalist content. Attie reverses this paradigm. By utilizing atproto, users gain real influence over what they see. However, the project by Jay Graber and Paul Frazee goes a step further – it ultimately aims to enable "vibe-coding," which is the creation of entire micro-apps and specific interfaces using voice or text commands.

During the presentation at Atmosphere, it was emphasized that conference participants would become the first beta testers of this solution. This approach shows that Bluesky treats Attie as a testing ground for a new era of social media, where the boundary between developer and user is completely blurred. The ability to design one's own algorithm means that every person using the protocol can have a unique social media experience tailored to their niche interests, rather than mass trends.

The introduction of Attie is also a signal to the entire tech industry: the future lies not in building more "walled gardens," but in creating tools that allow for free navigation across an open protocol. With Claude in the role of assistant, complex technology becomes accessible to anyone who can formulate their needs in natural language.

Vision of an agentic social network

The concept of an "agentic social app" is more than just filtering posts. It is a vision where artificial intelligence becomes our personal curator, protecting us from information noise and helping us establish valuable interactions. Attie, by leveraging the computing power of Anthropic and the flexibility of atproto, becomes a precursor to tools that could completely eliminate the need for a central moderator or an externally imposed content sorting mechanism.

"Attie allows you to design your own algorithm and create custom feeds in a way that was previously reserved for data engineers."

Although the application is currently in a closed testing phase, its potential is enormous. If the "vibe-coding" model takes off, we can expect an explosion of thousands of micro-communities, each with its own content distribution rules, its own aesthetic, and its own operational logic. Bluesky is not trying to be the largest service in the world – it is trying to be the foundation upon which everyone can build their own world.

A key challenge remains the issue of performance and operational costs associated with using large language models (LLMs) to analyze data streams in real-time. However, given the pace of optimization for models like Claude, this barrier may quickly disappear. Attie proves that the era of passive scrolling is coming to an end, and the time for conscious design of one's own digital reality is arriving.

The Attie project represents a bold step toward full user sovereignty on the web. Instead of fighting algorithms, Bluesky gives us the tools to create them ourselves, using the most advanced AI models on the market. This transition from platform-as-a-service to protocol-as-a-foundation for personal content assistants may be the most important trend in creative technologies in the coming years.
