Seems like working solution and overall and it seems to meet my requirements. However, the author needs to clarify the use of Gemini models. It feels like the Pro version can't be used at all, since when selecting Pro, none of the actions are carried out. In other words, only Flash works, and everything freezes when using Pro.

I recently installed NanoBrowser AI Web Agent and I'm very impressed! It installed smoothly, and I've been testing it out – it works beautifully. What I really like is how it can automate tasks right in my browser. The fact that it's an AI-powered agent that can handle web workflows is a fantastic concept, and it executes well. I appreciate that it runs locally, which is a big plus for privacy. It's great to see a tool like this available, and even better that it performs as described. If you're looking for an AI assistant to help with web tasks, I highly recommend giving NanoBrowser a try. It's a powerful and well-functioning extension!

Very promising. The core functionality is there, just needs a lot more refinement. Hopefully more features will be added soon. I'm betting this extension will blow up in the next few months, considering its open-source, community-driven nature.

现在各家的Aigent都不成熟,但作者更新很勤快,商店的版本也上来了,浏览器Aigent插件绝对是个重要分支,古哥的gemini嵌入浏览器方案现在就是一坨,还不开放和兼容
