Show HN: Open-Source Perplexity Comet and ChatGPT Atlas

We built a browser agent into the chrome sidebar for fun!You tell it what to do and it takes over your local browser like clicking, typing, filling out forms.Instead of downloading Perplexity Comet or ChatGPT Atlas, you can use this on any Chromium-based browser for free. Just plug in your API key and go.We use it daily to fill out forms and simple applications. It's surprisingly handy.

A lightweight Chrome extension for fast, deterministic web automation setup (Open Source & Free).

It records a filtered network HAR while letting you right-click to save labeled XPaths for clicks, inputs, selects, extracts, and waits — even on messy UIs. When you're done, it exports the HAR alongside a structured JSON step list ready to wire into Playwright or Selenium.

Useful as a fallback when browser agents get flaky, and handy for reverse-engineering unfamiliar web apps.

Temporarily free, we'll probably do a freemium model.

Co-Founder of CopyCat here - its free right now because we have no idea what people are going to use for this. Its so general purpose, so the login is to understand what people are prompting. We do not know anything that's happening on the browser, only what is happening in copycat. Helps us find bugs and release faster and possibly reach out to our users as well!
