Opening trainer · early access

Learn openings by the forks, not the grind.

We value your time. A 50-line Caro-Kann repertoire is 8 decisions, not 388 moves — Easy Memory drills the points where your lines branch and skips the filler in between.

Across the whole library that is 599 decisions instead of 8,973 replayed moves: 15× less repetition.

Your Sicilian doesn't have to be a personality flaw. Let's fix the gaps.

One position, three of your opponent's prepared moves. Answer each, undo to the fork, try the next. Minimal board movement, maximum recall.

What's inside

Forks, not filler

Answer a prepared reply, snap back to the fork, answer the next. The board barely moves.

Reviews that stay light

FSRS scheduling keeps the due pile small — no thousand-card guilt queue.

Puzzles from your openings

Real games that reached your positions, paused where someone blundered. Find the move they missed.

A coach that tells the story

Every move explained in a scrolling lesson. Click any line to jump the board back to it.

Spar inside your prep

Practice against a bot that plays your book until it runs out — then the engine takes over.

Build by playing

Create a course by moving pieces, or import PGN. Your lines, your rules.
