Cool! I had thought about doing the same but in a Chrome extension that would use Llama 3.2 with WebGPU, but when I tested it, it was very slow and sometimes crashed the browser.
I code and document code and imho Claude is superior, try to tell Gpt to draw a mermaid chart to explain a code flow... the mermaid generated will have syntax errors half of the time.
Imho IDs are more explicit, and a bless when working with large codebase apps, when trying to finding the related code to an element just grab the id and search for it.
