Show HN: Cursor's "Tab" Model in the Browser
Hey HN! Wanted to share a project me and @vicdotso (https://vic.so 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 https://news.ycombinator.com/item?id=33847504) work?
- pvg 1y agoDoesn't this send an awful lot of potentially private/sensitive browsing info to two places - your service and the LLM provider?
- killianlucas 1y agoOur goal is to build this locally— there's even some heuristics we've found (i.e clicking the same items in a row every time you visit a website) that can give really good completions without an LLM. Chrome is even starting to ship a small Gemma model in the browser, but we haven't seen great performance from Gemma yet. But yes, and I have the same concerns w/ this, code completions, Grammerly etc. Hopefully all these tools will follow the same trajectory (some usage with a cloud setup -> distilled into a small local setup).
- pvg 1y agoGrammarly, LLM code assistants, etc tell you upfront that this is happening and the type of info sent over is at least somewhat constrained. 'Everything I do in the browser, to multiple internet strangers' is a much bigger hurdle, especially without clear information. I think you need to figure out some way to safely demonstrate this to (informed) users - as it is, it feels far too iffy to even try which somewhat defeats the purpose of a Show HN.
- codingdave 1y agoSeems like algorithms to send me the next content in my browser is exactly where social media went wrong. Why would anyone want an AI equivalent?

- killianlucas 1y agoIt depends where the tech is applied IMO — for your information diet it's destructive to give up any control. For filling out forms, copying and pasting between tabs, other web drudgery.. I think it's just a bad computing experience, and people would welcome something better than copy/paste (tech from half a century ago!)
- codingdave 1y agoIf you think it is a bad experience, then make a better one, don't automate the bad one.
