I just built a Google Chrome chess extension. It is a new tab page full of chess puzzles. It has various difficulties, and a speed run game (solve as many puzzles as you can in 60 seconds). I personally think it's the coolest browser extension I have ever seen (being objective as possible).

It works on Chrome and Brave for now. Planning a Firefox release soon.

If you're a chess fan, you'll probably love it, but if not, let me know why (I'll try to improve it).
