Tip: you can also build lines on the board. Open a line, tap Edit here, move any piece, then Add line.
Paste or upload PGN you exported or copied from Chessable (moves only; comments are ignored).
Why no Chessable login? Asking for your Chessable password would mean handling someone else's password, which is a security risk, and automated logins and downloads likely break Chessable's terms. Exporting the PGN yourself keeps your account safe.
Upload screenshots of move lists. Text is read on your device; images never leave it. Each screenshot becomes a line, merged as variations.
For your personal use; only moves are read, no text is stored.
Tap a move to open its branches. Tap ▶ to train from that position.
