Show HN: Cursor's "Tab" Model in the Browser

Hey HN! Wanted to share a project me and @vicdotso (https://vic.so) built this month— it predicts the next thing you’re going to do in your browser, then lets you press CTRL+CTRL to accept the prediction.

It’s incredibly fast. Uses Qwen-3 on Groq, with context of your DOM + the DOM from your last tab. Video demos are on the chrome extension page.

We worked forward from this theory: Code models exploded in popularity once you could use them for code completions (Github copilot, Cursor’s tab). Maybe computer-use models will have the same beginning?

Would love your thoughts on this / related ideas. Will computer-use products ever take off? What will that product look like? Why didn't Natbot (https://news.ycombinator.com/item?id=33847504) work?
