The team from Bluesky has built another app — and this time, it’s not a social network, but an AI assistant that allows you to design your own algorithm, create custom feeds, and, one day, vibe-code your own app.

At the Atmosphere conference over the weekend, Bluesky’s former CEO, Jay Graber, now chief innovation officer, and Bluesky CTO Paul Frazee, presented the AI app, called Attie, for the first time. Conference attendees will become the initial beta testers for the new experience, which leverages Anthropic’s Claude under the hood to create an agentic social app built on Bluesky’s underlying protocol, the AT Protocol (or atproto for short).

“It’s a new product — it’s not a part of the Bluesky app,” explains interim CEO Toni Schneider in an interview. (In addition to his CEO role, Schneider is a partner at Bluesky backer True Ventures.) “We’ve launched a lot of things inside Bluesky — Starter Packs and custom feeds, and all those kinds of things. This is a standalone product, and it’s the first one that’s built by Jay’s new team.”

With Attie, anyone will be able to build their own custom feed just by typing in commands in natural language, the same as if they’re chatting with any other AI chatbot. To use the app, people will sign in with their Atmosphere login (meaning their login for any app that runs on atproto, which includes Bluesky). Attie will immediately understand what you’ve been talking about, what sort of things you like, and more, because Bluesky and the wider ecosystem are open systems that share data across apps.

You can ask Attie questions, like what posts you might like to see or repost, and you can use the app to curate your own custom feed, personalized to you.

“You control it, you shape it, without having to write code or know how to set up these feeds,” Schneider says. “It’s the beginning of just having a lot more people be able to build on top of the Atmosphere.”

Plus, he adds, “It is an AI product, but it’s an AI product that’s very people-focused … We think AI is a very powerful technology, but we want to make sure that we use it to build things that really benefit people.”

At launch, Attie can be used to build and view these feeds, which will later become available to you within Bluesky or any other atproto app. Over time, the plan is to allow Attie’s users to vibe-code their own social apps as well as build tools for other people.

Schneider says that Graber and her team began working on the app a few months ago, which was around the same time she decided to return to building, instead of running the company.

“I think she realized that there was so much more that she wanted to build, and just doing the CEO job kept her busy, and she felt like she wanted more time,” Schneider tells TechCrunch. “As she spent more time, [and] got freed up, I think it became clear that this is her happy place. She’s an amazing leader and visionary, and we want her building more things and not worrying about operating the company,” he says.

Graber says today, AI is being used by the major platforms to serve themselves, not their users, by trying to increase people’s time spent in their apps, harvesting data, and controlling their algorithms.

“We think AI should serve people, not platforms,” Graber said in her announcement of Attie. “An open protocol puts this power directly in users’ hands. You can use it to build your own feeds, create software that works the way you want it to, and find signal in the noise.”

Graber’s decision to once again focus on protocol and product was followed by the company’s announcement that it now has $100 million in additional funding from a round that closed last year. The team hopes that news serves as a signal to the wider community that Bluesky will continue to be around.

“It means we have three-plus years of runway, whi
