Open the trainer

Everything you need to train your openings

The current Opening Trainer is available without charge. That includes:

Train your own White and Black repertoires
Use position-level FSRS scheduling
Import existing lines and connected games
Build very large repertoires at no charge
Export your repertoire whenever you want

All the core training tools, at no cost

Free means a real opening-training workflow, not a sample lesson or a demo repertoire.

Adaptive spaced repetition

Every opening position is scheduled with FSRS, so you review each move when it needs reinforcement.

Your complete repertoire

Build White and Black opening trees or import the lines you already have from PGN.

Training from your games

Use your Lichess and Chess.com games to reinforce prepared moves and find gaps to repair.

Export anytime

Download your repertoire whenever you want. Your opening preparation is never locked in.

Why is it free?

Built to solve a real training problem

OnlyMove began as a personal tool for retaining a large opening repertoire. The goal is to keep the Opening Trainer free, including for players who want to build very large repertoires.

Read the story behind OnlyMove

Build it once. Remember it.

Bring the openings you play and let spaced repetition keep them ready for your next game.
