HoloTab: HCompany’s AI Browser Agent That Actually Works, No Setup Required

HCompany has been quietly building some of the most impressive computer-use AI models out there. On March 31st they dropped Holo3, which they claim is one of the most powerful models in this space. I’ve been playing with it, and honestly? The claims hold up.

But here’s the thing: powerful models are useless if nobody can actually use them. That’s where HoloTab comes in.

HoloTab is a Chrome extension that puts Holo3 directly into your browser. No API keys, no Python scripts, no command line. You install it, you tell it what you want done, and it just… does it. It navigates websites, fills forms, clicks buttons, extracts data—the whole nine yards. The vision models and action planning all run in the background; you only see the result.

The Routine Feature Is the Killer App

Most browser automation tools make you record macros or write selectors. That’s fine if you’re a developer, but it’s a non-starter for everyone else.

HoloTab’s “Routines” feature is different. You hit record, then do the task yourself once—clicking, typing, maybe narrating what you’re doing and why. HoloTab captures everything: your screen, your actions, your context. It builds a routine that actually understands the goal, not just the keystrokes.

Once recorded, you can replay that routine anytime, or schedule it to run automatically. Think about the use cases:

• Cross-referencing competitor prices across twenty e-commerce tabs and dumping them into a spreadsheet
• Scraping job listings from a dozen career pages every morning
• Filling out repetitive forms across multiple sites
• Monitoring product availability or price changes

I’ve been using it to track GPU pricing across cloud providers. It’s not perfect—sometimes it gets confused by CAPTCHAs or weird UI layouts—but it handles 90% of the work without intervention. That’s way better than anything else I’ve tried at this price point.

Built for Normal People

Computer-use AI is one of those technologies that’s going to reshape how we work, but most implementations are still locked behind engineering teams. HCompany is taking a different approach: make it free, make it a browser extension, and let anyone use it.

HoloTab is available now on the Chrome Web Store. No waitlist, no enterprise sales call, no “schedule a demo.” Just install and go.

Is it perfect? No. The model can be slow on complex multi-step tasks, and it occasionally misclicks or misreads a page. But for a v1 product that’s free? It’s genuinely impressive. The routine recording alone is worth the install.

If you’ve been waiting for an AI browser agent that doesn’t require a PhD in prompt engineering to use, this is it. Go grab it and see what it can do for your workflow.
