Import PGN Repertoire

Warning: Importing a PGN will replace the entire selected repertoire and reset spaced repetition progress for those lines.

Export & Repertoire Baking

Choose an option below to save your repertoire moves, copy the developer code directly, or compile your current custom openings into a self-contained web app.

Download Standard Chess PGN (.pgn)

Saves active color opening branches as a database PGN. Excellent for importing into external chess suites like Lichess, Chess.com, or ChessBase.

Copy Repertoire Developer Variable (JS)

Generates and copies a clean variable representing the active trees. Replace the block between the PANDA_BAKE_IN_DATA_START and PANDA_BAKE_IN_DATA_END sentinel comments in the source to make modifications permanent.

Download Self-Contained Web App (.html)

Downloads a complete clone of this HTML application with your active repertoire pre-packaged into the source code as the default fallback state. Requires opening the file from your local disk — sandboxed previews can't access their own source.
