Ask HN: AI Browser Automation

I was trying to look for an AI browser like Perplexity or OpenAI's, but one that I could run on a model & key of my choice.

I found BrowserOS (https://news.ycombinator.com/item?id=46721474), but in my experience, it fell pretty short of even being able to do tasks.

Does anyone know of any FOSS projects like this that actually deliver? it seems like there's not really much in the space
