RecallChess

Memorize your opening repertoire. Imports Chessable + PGN, reviews chess.com / lichess games for off-book moves.

# RecallChess — Repertoire-divergence overlay for chess.com & lichess Stop forgetting the openings you already studied. You drilled the line on Chessable. You played the wrong move anyway. After the game ends Game Review catches your tactical errors — but your opening memorization is never tested. So a week later, you reach the same position, sense the move is wrong, and play it anyway. RecallChess plugs that gap. The moment a chess.com or lichess game ends, an overlay appears on the board showing exactly which move drifted from your prep, the book moves you should have played, and a one-click jump back to the Chessable variation that covers it. ## What it does • Pinpoints the first move you (or your opponent) left book, on every chess.com / lichess game review and the live post-game screen. • Shows the actual moves your repertoire prescribes from the position you drifted from — labelled, ranked, deep-linked to chessable. • "Continuations in the book" panel from any position lets you explore alternative book lines without leaving the game. • Off-book hotspots: aggregate every game into a ranked list of the positions YOUR real games keep leaving book — drill the spots that actually bite you, not random theory. • One-click Chessable course import. No manual PGN, no spreadsheet. Sign in to chessable.com and the extension imports the courses you already own. • Manual PGN upload too — combine purchased courses + your own files into a single repertoire. ## Privacy posture • Your repertoire and games never touch our servers. Stored only in your browser (IndexedDB on the web app, chrome.storage.local on the extension). • Your chessable session token is read on-demand for a sync, used immediately, and never written to extension storage. • Sign-out wipes all user-tied storage from your device. • Authentication uses Google Firebase. No analytics SDKs, no tracking, no advertising networks. ## How to use 1. Install the extension. 2. Sign in at recallchess.app (free). 3. Connect your Chessable courses with one click — or upload a PGN. Pick what you're actively studying. 4. Play and review on chess.com / lichess. The overlay shows up automatically. ## Supported sites chess.com · lichess.org · chessable.com (course import only) ## Pricing Free during open beta. ## Privacy policy https://recallchess.app/privacy.html ## Contact hello@recallchess.app
