Bluesky just made its boldest move yet — and a significant chunk of its own community is furious about it.
The decentralized social network launched Attie, a standalone AI assistant powered by Anthropic's Claude that lets anyone build custom algorithmic feeds using plain English. No coding required. Just describe what you want to see, and Attie's coding agent generates a working feed on the AT Protocol in seconds.
The catch? Over 125,000 users blocked Attie's account within days of its announcement, making it the second-most-blocked account on the entire platform — right behind J.D. Vance.
Jay Graber Built This Herself
Attie isn't a side project from a random product team. Jay Graber, Bluesky's co-founder, stepped down as CEO specifically to build it. She moved into a new Chief Innovation Officer role and assembled an "Exploration Team" dedicated to pushing the AT Protocol's boundaries.
Toni Schneider — the former CEO of Automattic (the company behind WordPress) — stepped in as interim CEO to handle Bluesky's day-to-day operations. That leadership shuffle tells you how seriously Bluesky is betting on AI-powered social experiences.
The timing coincided with Bluesky disclosing a $100 million Series B round (led by Bain Capital Crypto, raised in 2025), giving the company significant runway to experiment.
How Attie Actually Works
Attie uses what the team calls "vibe coding" — a term borrowed from the broader AI-assisted development movement. Here's the workflow:
- Sign in with your AT Protocol credentials (your Bluesky login works)
- Describe what you want in natural language — e.g., "Show me posts about AI research from accounts with over 1,000 followers, excluding anything political"
- Claude generates the feed algorithm behind the scenes
- Your custom feed appears instantly, pulling from the open AT Protocol data layer
Because the AT Protocol is an open, decentralized system, Attie can read public data across the entire network. It understands your existing follows, interactions, and interests the moment you log in — no training period needed.
The app is currently in closed beta at attie.ai, with a waitlist open to Bluesky's 40-million-plus user base. The team hasn't decided whether Attie will be free or paid.
The Long-Term Vision Is Bigger Than Feeds
Custom feeds are just the starting point. Bluesky's roadmap for Attie includes letting users build entire social apps through natural language prompts. Imagine describing a niche community platform — say, a book club with threaded discussions and reading lists — and having Claude scaffold the whole thing on top of the AT Protocol.
This positions Attie as more than a feed tool. It's potentially a no-code app builder for decentralized social software, something that doesn't exist anywhere else in the market.
Why 125,000 Users Blocked It Immediately
Bluesky's community has a strong anti-surveillance, pro-privacy identity. Many users migrated from X (formerly Twitter) specifically to escape algorithmic manipulation and AI-powered content systems. Introducing an AI assistant that reads your social graph felt, to many, like a betrayal of those principles.
The backlash was immediate and organized. Within 72 hours, blocking Attie became a form of protest — a way for users to signal that they didn't consent to AI systems accessing their public data, even on an open protocol.
The irony is hard to miss: the AT Protocol was designed to make data portable and open. Attie simply uses that openness in a way many users didn't anticipate or want.
What This Means for the AT Protocol Ecosystem
Attie is the most ambitious consumer application built on the AT Protocol outside of Bluesky itself. If it succeeds, it validates the idea that decentralized social protocols can support a rich ecosystem of AI-powered tools — not just alternative Twitter clones.
If it fails, it raises uncomfortable questions about whether "open" protocols can coexist with AI systems that many users view as inherently extractive.
Either way, the tension between openness and consent is now the defining debate in decentralized social media.
The Bottom Line
Attie represents a genuine innovation: AI-powered social feed creation on an open protocol, built by the person who designed that protocol. The technology works. The vision is compelling. But Bluesky's community is pushing back hard against the premise that openness means AI gets to read everything — and that tension won't resolve easily. Whether Attie becomes the killer app for the AT Protocol or a cautionary tale about shipping AI into a privacy-conscious community depends entirely on how Bluesky navigates the next few months.
