It's really bad, much less useful than even the first public version of chatgpt. Even once you manage to log in, most of the time it doesn't even give something that compiles, it calls functions/variables which don't exist. The first line of the main had 2 errors...
I finally could login and I would prefer I had not. Honestly, it is pathetic that something like this has so many positive comments. I guess most people commenting didn't even try sketch.dev
