Rent a dedicated Stockfish 18 server by the minute. Analyze your entire game in parallel across its cores, or point all of them — up to 192 — at a single position.

Analyze a whole game
Positions are spread across your server's physical CPU cores, one position per core, and analyzed in parallel.
Pick up where you left off
We snapshot the running Stockfish process and store it for 48 hours. Come back later to resume or deepen the analysis, and Stockfish picks up exactly where it left off.
Rent a big server for single-position analysis
Rent a dedicated machine and run Stockfish on a single position with every core it has: up to 192 physical cores on AMD EPYC Turin at 4.5 GHz, one thread per core rather than two sharing one. Billed by the minute, and from 64 cores up it holds the 6-piece Syzygy tablebases in memory too, 73 GB of them, on top of the 5-piece set every machine carries.
Play moves to explore
Drag a piece to add a variation, or click an engine line to insert it. Variations are analyzed like any other move, and every level of nesting gets its own color.
What a human would play
Maia 3 predicts the moves players at a given rating actually pick, at your game's ratings, and plays the position out from there.
Why a move was bad
When a blunder comes down to a concrete tactic, you get one sentence and a board you can step through. When it does not, you get nothing: it stays quiet rather than guessing, and no part of it is written by an AI.
