Congrats! How are you planning to make the project sustainable (from a financial, and dev work/maintenance pov)?

my guess is it's just an electron app or chromium wrapper with an ollama wrapper to talk to it (there are plenty of free open source libs to control browsers).

No wireless. Less space than a Nomad.

The demo buying toothpaste shows the difficulty of these tasks. Toothpaste itself was very underspecified, and it essentially randomly chose from a huge list. Some tasks may have past actions that could help guide, others won't have any to inform. Failure cases abound -- maybe the toothpaste you previously bought is no longer available. Then what? Ultimately how much time did this particular example save since you need to double check the result anyway? This is what doomed Alexa for the purchasing experience that Amazon assumed it would enable in the first place.

I think it'd be better to show more non-trivial examples where the time savings is clear, and the failure cases are minimized... or even better how it's going to recover from those failure cases. Do I get a bespoke UI for the specific problem? Talk to it via chat?

This whole world is non-trivial. Good luck!

Would this be possible for Firefox?

IIRC, Firefox's web extension API does not provide access to accessibility tree as well.

I'm not GP, but I agree that if your goal is to empower the end user and protect him from corporate overlords, then Firefox is a more logical choice to fork from.

So would this or any AI browser go out and fetch a list of the best deals for my trip to Iceland? After Show me all the options it has found for flights, hotels, car rentals and show cheapest/best prices with all details (fly out of and into with times) to even allow me to pay for each item on same page I asked it to do so? As well it could group the overall best deal with details and then i can just click to pay ins…

It seems that the next evolution of SEO will be too skip the SE and simply O for the LLMs.

Great points! For sure, the whole agentic browsers space is still super early.

We are also just getting started and trying to narrow down on a high-value niche use-case.

There are few repetitive, boring use-cases where time saving could be meaningful -- one example: Walmart 3rd-party sellers routinely (multiple times a day) keep checking prices of the competitor products to price their products appropriately. This could be easily automated with current agentic browsers.

The default model is Gemini. You can bring your own API keys and change the default to any model you local. Or better run model locally using Ollama and use that!

The default is a remote Gemini call?

Yes, right now using Gemini API on our liteLLM server (we can't expose API key on client side).

We are working on smaller, fine-tuned model too, which will be the default soon! It should be much faster and precise at navigation tasks.

But in reality, would much more consistently be automated by a single playwright script.

I would prefer this as a browser extension, not as its own browser application.

We had this exact thought as well, you don't need a whole browser to implement the agentic capabilities, you can implement the whole thing with the limited permissions of a browser extension. There are plenty of zero day exploit patches that Google immediately rolls out and not to mention all the other features that Google doesn't push to Chromium. I wouldn't trust a random open source project for my day-to-day brows…

Brave Browser (70M+ users) has validated that a chromium fork can be viable path. And it can in fact provide better privacy and security.

Chrome extensions is not a bad idea too. Just saying that owning the underlying source code has some strong advantages in the long term (being able to use C++ for a11y tree, DOM handling, etc -- which will be 20-40X faster than injecting JS using chrome extension).

True, there are plenty of libs already available to do such an automation if you are (or can hire a) dev.

But for non-technical folks, agentic browsers seems like a good UX to build such and many more automations.

Is BrowserOS-OS on the roadmap? (Will you ever make a better FydeOS, or if you're laser-focused, perhaps be open to sharing some with them, so they could?)

Yes! We are excited to build BrowserOS-OS! I think with agents the whole UX can be re-imagined.

I'll check out FydeOS!
