How it works
Screenshot in. Best move out.
Three taps between a position you’re stuck on and the move that wins it.
01Snap the board
Take a screenshot in Chess.com or Lichess — or paste a FEN. The position is rebuilt piece by piece, on your phone.
02Follow the reply
Play the move and the app shows what it forces. Move any piece yourself and the engine re-analyses on the spot.
03Finish it
The line runs all the way to checkmate, with an evaluation bar tracking the position at every ply.

Features
Everything the strong players use, in your pocket.
The line to checkmate
Not just one move — the reply it forces and the continuation, with an evaluation bar tracking every ply.
Second-best move
Compare the top candidates side by side and understand why the engine prefers one over the other.
Drag to explore
Move any piece and the engine re-analyses instantly. Test an idea without leaving the board.
My Positions
Save the positions you want to come back to and share any of them as a link that opens straight in the app.
Boards & pieces, your style
Six piece sets and a range of board palettes — from tournament green to walnut, bubblegum and icy sea.
Available in 23 languages. Free to start — Pro unlocks the evaluation bar, second-best move and unlimited scans, or top up with keys instead.
Does it need an internet connection?
No. Board recognition and engine analysis both run on your phone. Once the app is installed you can use it fully offline — on a plane, on the underground, anywhere.
Do I have to create an account?
Never. There is no sign-up, no login and no profile. Nothing about your positions is uploaded or stored on a server.
Which apps can it read screenshots from?
It is built around Chess.com and Lichess and reads the common board themes and piece sets on both. Unusual styles can still defeat it — heavily textured or translucent boards, and 3D piece sets, are not supported. Diagrams from books and websites often work too, as long as the board is square-on and unobstructed.
What if the scan misreads a piece?
Take the screenshot again with the whole board visible and nothing overlapping it — that fixes most misreads. If a particular board theme fails every time, send us the screenshot; that is what makes recognition better.
Is it free?
Yes — you start with an initial allowance of free scans. After that there is more than one way to carry on: Pro removes the limit and unlocks the evaluation bar, the second-best move and direct import from Lichess and Chess.com, available monthly, yearly or as a one-time lifetime purchase. You can also top up with keys instead of subscribing.
Is using it cheating?
Analysing your own positions is how every strong player studies. Using it during a live rated game against another person breaks the rules of every chess site — that is on you, not the app.
Which languages does it speak?
23 of them, including English, Spanish, Portuguese, German, French, Italian, Dutch, Norwegian, Danish, Indonesian and more.
