FAQ

What games can I import?: Paste PGNs from Chess.com or Lichess (and most standard PGN exports). You can paste multiple games in one go for bulk upload.
How do you find key moments?: It’s our secret sauce: in short, we use in-house, sophisticated techniques that blend chess engine accuracy with natural-language understanding from fine-tuned models. That helps us surface the moves that mattered—blunders, mistakes, and missed wins—so you can focus on the highest-impact positions.
What can I ask the AI Coach?: Ask “what was the best line?”, “why is this a mistake?”, or “what should I look for next time?” while reviewing a specific position.
What are weekly reports / lessons?: Weekly reports summarize your trends and recurring patterns and suggest what to train next. Lessons are a structured plan with focus areas and exercises.
Are puzzles based on my games?: Yes—practice puzzles are generated from positions in your own games so the tactics and themes stick.
