OF THE DAY Attie by Bluesky The first agentic AI app to go vi
What Is Attie?
Attie is an AI assistant built by the Bluesky team that lets any user design their own social feed algorithm using plain natural language -- no code required. Type "Show me posts about AI agents from people I follow, ranked by engagement, excluding reposts" and Attie generates and deploys the algorithm as a live feed. It's powered by Anthropic's Claude and built on ATProto (the AT Protocol underlying Bluesky).
The Controversy: Why 125,000 Users Blocked It Attie's virality is a masterclass in product-market fit tension. Bluesky's users migrated from Twitter/X specifically to escape algorithmic manipulation and AI-driven feeds. The platform's core value proposition was human-curated simplicity. Attie's launch -- even though it gives users more control -- felt like a betrayal to a community that valued AI-free spaces. Key lesson for agent builders: even well-intentioned agentic features require user trust architecture -- explicit opt-in, transparency about what the agent does, and an easily accessible off-switch. This maps directly to the NIST CAISI Kill Switch T1 (app-level).
