Have you guys tried still theory?

It is! Although it's only a few days old, so it might have some issues you might run into. Otherwise, the creator seems to be working pretty hard on it.

Hello!! Stilltheory creator here . I'm so glad you guys are enjoying using the site. Let me know if you have any ideas for me to implement in the near future. I'm currently working an a 'Spar with the Computer' feature where the user drills through all the lines in their repertoire against the computer. What do you guys think?
Again, really happy I found this post! Thank you!
Hey guys,
I just found this really cool site called stilltheory. It's like openingtree, but more aesthetically pleasing with the way it presents openings in branches. It's pretty new, and only works for Lichess and Chesscom (It can't load PGN files yet). What do you guys think?
