I was thinking of the Codex app.

Particularly the left sidebar and conversation view look near identically structured.

Cool talk, thanks for sharing. What happened to the project? I see no mention to it on the Github Next website and even internal links to it like on page [1] go to a 404 - https://githubnext.com/projects/ace/

I rather like Ace better because the key problem right now is teams not working together and shipping the wrong things. When AI can generate the code, then it feels like product should be bringing the functional vocabulary and grammar while the engineering team provides the technical grammar to build the right thing.

This app is just another "let me talk to product, copy their convo, go off and build this in isolation with an agent" which I think is directionally wrong.

The "rooms" or "streams" should be multi-player instead of product looking at it at the end saying "no, go fix that" and dev copies text from one source and pastes into another.

ace appears to be an experiment to make a multi-user experience on top of the codex UI.

the copilot app looks more like just a straight clone of the codex UI (and the new antigravity UI, which is also a straight clone of the codex UI)
