I tried this out real quick just to see for myself. First it was slow for me, if I wasn’t wanting to try it out I may have closed the tab, but I did a search for a question I recently googled (that was an example of an annoying google search.) I searched “Python arcade sprite opacity“ and while the first three results were the same as google the fourth was a github link to the project itself and brought me to the answer (which wasn’t on page 1 of google for me, although it was on page two.)
So you need to speed it up, but it does look good for searching documentation at least.
There are other options that may be better, but in general, very few people are looking for them.
