For players tired of forgetting their prep
ChessEcho is a board-first chess opening trainer and opening repertoire trainer built around repetition on the board. Drill your lines until the positions feel automatic, not just memorized.
Features
Study session
Drill your lines on a real board - the same recall you'll need in a game, not a flashcard quiz.
Opening explorer
Walk the full variation tree, compare pawn structures, and save the lines that fit how you play.
Opening library
Browse curated openings by family, color, and level. Add the lines you want, skip the rest.
Progress tracking
Accuracy, streaks, and session history show you which lines need more reps.
How it works
Pick from a curated library organized by family, color, and level. No loose PGNs, no building courses from scratch - just the lines you want to play.
Practice move by move against real positions. No flashcards, no multiple choice. The same recall you'll need sitting across from an opponent.
See which lines are solid and which need more reps. Your accuracy, streaks, and session history tell you exactly where to focus.
