Dial in the rating you're chasing and Chesserino plays back the move a player there would actually find — not a cold engine line. Close the gap one game at a time and watch the bracket you've been stuck in shrink behind you.
Sound and safe — supports e4, but a touch passive.
Most days you just pick a rating and play. When you sit down to study, flip to Pro and the full workbench appears.
Each panel is a focused tool — opened from the sidebar, powered by your local engine, with nothing syncing anywhere.
A local mistake-pass over your game. Replays the critical moments and lets you re-try the turning points.
Build a private repertoire and drill due lines from a spaced-repetition queue — entirely on your machine.
Every analysed position and review, searchable and offline. Nothing leaves your computer.
Pick Stockfish, Fairy-Stockfish or Maia 3. Set depth, lines and the human-like strength model.
Light or dark, board themes, arrow styles and overlay opacity — make it yours, then forget it.
Flip the overlay, step the engine, cycle suggestions or jump to review without touching the mouse.
Chesserino bundles real engines that run on your CPU. Switch between cold tactical truth and human-like prediction depending on what you're doing.
Full-strength evaluation for analysis, review and import.
Chess960 and variant positions, handled locally.
Predicts the moves a player at your rating would actually find.
The extension reads the position from the page and hands it to the local app. It detects the site and the page type, and adapts so it's a study tool — not a cheat.
On a live, rated game Chesserino locks suggestions. You see the evaluation bar — never a move to copy.
On analysis and puzzle pages the overlay shows full arrows, lines and the human-strength suggestion.
Reviewing a finished game or a pasted PGN/FEN unlocks the whole toolkit — it is your study, after all.
