Paste a YouTube link.
Drill every opening line.

Import

Paste a YouTube link and we'll extract every opening line from the video. Or import from a Lichess study or PGN.

Organize

Group lines into repertoires for white or black. See how your variations branch in a move tree.

Drill

Train on an interactive board. Spaced repetition brings back lines you struggle with and fades the ones you know.

YouTube

Paste any chess video link. Openings.gg extracts every opening line — move validated, timestamped, ready to drill.

Lichess

Connect your account or paste a study link. Chapters become drillable lines instantly.

Chessable

Copy any line from a Chessable course and paste it in. Moves and annotations are extracted automatically.

PGN

Paste raw PGN from ChessBase, databases, or your own notes. Multi-game files split automatically.

Game Sync

Connect your Chess.com or Lichess account. We analyze your recent games and boost the lines your opponents actually play — so you study what matters.

Not another course platform

No locked content, no $30/month for someone else's repertoire. Import your own lines and train exactly what you play.

Spaced repetition that works

Same algorithm behind Anki, adapted for chess. Lines you nail fade away. Lines you botch keep coming back.

See the full tree

Lines with shared moves merge into a branching tree. See where your variations diverge and spot gaps in your repertoire.
