I know I've seen something like this on hackernews before. SaaS for taking over the IDE at any point of a recording, just without the video.

EDIT: https://news.ycombinator.com/item?id=28207662

Seems this but with a slightly different spin?

EDIT2: Gave it a go. Works as intended, so good job on that. The video being a video, makes it a bit awkward though - if I stop the recording and edit some part, I'd want to see the changes live, but for that I guess I'd have to start the server myself? And when I hit play, my changes got deleted anyway (?).

As for the usefulness aspect, personally I am not sure that this has a benefit over e.g. watching youtube tutorials/following books. I watched one of the videos and I'd have to concentrate on the video, the text and audio at the same time, and it wouldn't be me typing the code anyway, so I'm not sure how much I'd remember of it. I'd have to stop, open a new project and try to rewrite it myself to memorize the concepts deeper. But that's just my personal take - might be that there's a big userbase for such interactive learning!

Interesting concept, had never seen something like this. Demo video was short and to the point, well done!

Coding session these days is someone typing into Claude Code and waiting. I think this would have been a decent idea a few years ago. Humans typing code into an editor is going to be as rare as debugging assembly.

Already waiting on twitch ASMR coders that will use your tool =)

Kudos for actually making it open source.

Wishing you luck for this project!
