Bluesky's latest app, Attie, utilizes AI to provide you with complete control over your social media feed.

      The standalone application, developed on the AT Protocol and powered by Anthropic’s Claude, was introduced by Jay Graber at the ATmosphere conference. Graber had stepped down from the CEO position at Bluesky to focus on this project. Currently, the app is invite-only, with a waitlist available.

      Bluesky's primary distinction from X and Threads has always been its custom feed system, enabling users to subscribe to algorithmically curated streams created by anyone, not just the platform itself. However, the challenge has been that constructing these feeds necessitated coding knowledge.

      Attie, a new standalone app revealed at Bluesky’s ATmosphere developer conference, aims to bridge this gap completely. It allows users to create personalized social feeds by simply describing their preferences in plain language, similar to how they would interact with an AI assistant.

      Prompts showcased on the app’s website include phrases like “Show me electronic music and experimental sound from people in my network” or “Builders working on agent infrastructure and open protocol design.”

      The app converts these descriptions into functional feeds, which can then be utilized within Bluesky or any other applications built on the AT Protocol. It operates using Anthropic’s Claude in the background. At launch, Attie is invite-only, initially accessible to ATmosphere conference attendees, with a public waitlist available.

      The app was created by Jay Graber and a newly established group known as the Exploration team. Graber, who co-founded Bluesky and served as CEO, stepped back from daily operations a few months prior to return to development. Toni Schneider, a partner at True Ventures, one of Bluesky’s supporters, has assumed the role of interim CEO. Graber introduced Attie at the conference alongside Bluesky CTO Paul Frazee.

      Attie functions as an independent product, distinct from the Bluesky app, and is based on the AT Protocol, which is the open-source decentralized framework supporting Bluesky and a growing array of other applications collectively termed the Atmosphere.

      Users can log in with their Atmosphere credentials, meaning their existing Bluesky account is applicable. Since the AT Protocol operates as an open data system, Attie can quickly grasp a user’s interests and social context across the entire ecosystem, not limited to Bluesky itself.

      The long-term vision for Attie is more expansive: the intention is to enable users to vibe-code their own social applications from the ground up, not merely customize feeds. Schneider described this as “the beginning of enabling many more individuals to build on top of the Atmosphere.”

      Jay Graber from Bluesky was clear about the product's philosophy. In a blog post accompanying the launch, she stated that major platforms “aren’t trying to fix” the issue of AI-driven signal degradation in social media: “They’re leveraging AI to prolong user engagement on-platform, to collect training data, and to influence what users see and believe through opaque systems they don’t control or select.”

      Attie is positioned as the opposite: AI that empowers users to regain control over their algorithmic environment rather than diminish it. The company, which has recently secured $100 million and boasts over 43 million users, has framed Attie as its dedicated space for agentic social experimentation, separate from the main Bluesky application that those users depend on.
