Nice work! I would assume something like this would quickly run into rate limiting on google, does that happen or did you do something to mitigate?
You can even make your tool offline and private :)
Add a few transformers on top, and you can have it generate dubious code.
Though if you want to be competitive you'll probably need a few phd and M$ of computing resources or use some free tpu like https://colab.research.google.com/ and hope to not get rate limited :)
Another one to consider is Google and Stackoverflow offical API
The extension run in nodejs environment, and use fetch-node to get page content. I assume it's similar to how someone use google on broswer
