Is Theoria only for advanced players?
No. It's built for improving players, especially if you know basics but still lose games early.
Your opening
shouldn't be a coin flip.
Learn the plan behind every line you play, then drill the ones you keep getting wrong. The first 15 moves stop being a guess.

Quick Answers
No fluff. Just the stuff you'd ask before committing to a training app.
How is this different from an opening database?
Databases show moves. Theoria teaches the plan and makes you practice it until it's automatic.
Can I train both White and Black repertoires?
Yes. You can build and train both, with separate recommendations and progress.
Can I start free?
Yes. You can start with free access and upgrade later for full depth and advanced tools.
Does game import work with Lichess and Chess.com?
Yes, in beta. You can connect accounts and review your most common opening deviations.
