HoloTab: HCompany’s Chrome Extension That Actually Uses AI to Do Stuff in Your Browser

HCompany just dropped something I’ve been waiting to see for a while: a browser extension that doesn’t just summarize articles or suggest replies, but actually does things in your browser. They call it HoloTab, and it’s essentially a computer-use AI that lives in Chrome.

On March 31st, they released Holo3, which they claim is one of the most powerful computer-use models out there. I haven’t benchmarked it myself, but the demos look legit. HoloTab is the practical, no-fuss wrapper around that model—a Chrome extension that navigates the web like a person would. You tell it what you want, and it handles the clicking, typing, and decision-making. No API keys, no Python scripts, no terminal.

The routine feature is the real killer

Most AI agents I’ve tried are good for one-shot tasks: “book a flight to Tokyo” or “find the cheapest monitor on Amazon.” But the real pain points are repetitive workflows that eat up your afternoon. HoloTab’s “Routines” feature directly addresses that.

You start a recording, and HoloTab watches what you do in your tab—your clicks, your scrolls, even your narration if you talk through it. It captures the context, not just the keystrokes. Once you stop, it generates a routine you can rerun or schedule. Want to scrape competitor pricing from twenty e-commerce tabs every Monday morning? Show it once, and it’ll do it on its own from then on.

I’ve seen this “record and replay” approach tried before with browser automation tools, but they usually break the second a website changes its layout. HoloTab uses vision models to understand what’s on screen, so it’s more resilient. Whether that holds up in practice is something I’d need to test, but the architecture makes sense.

Free and frictionless

The smartest thing HCompany did here is make it free and zero-setup. No sign-up gate, no “request early access” form. You just install the extension from the Chrome Web Store and start using it. That’s how AI tools should ship.

Computer-use AI is one of those things that sounds futuristic until you actually try it. HoloTab makes it feel mundane in the best way—like, “oh, of course my browser can just do that now.” It’s not perfect, I’m sure. Vision models hallucinate, and complex multi-step tasks will probably still fail sometimes. But the direction is right. And for a free tool that takes 30 seconds to install, it’s worth a spin.

If you’ve been waiting for an AI that actually does stuff instead of just talking about it, this is probably it.
