Régence 0.9 — reviewing a game
You just lost. You vaguely know where it slipped away — without knowing why. Régence replays the game move by move, with the world champions’ engine, on your Mac: every move is graded, both players’ accuracy is measured, and the evaluation graph shows where it was all decided. The game review you know — without the cap.
Régence runs entirely on your Mac. No server, no queue, no counter.
Analyze 3 games or 300. Nobody counts, nothing expires.
Your games, your analyses, your statistics: nothing ever leaves your Mac. No account required.
On the train, at a tournament, on holiday: Régence doesn’t need the Internet.
Quiet mode, on by default, analyzes without spinning up the fans. In a hurry? Performance mode runs twice as fast.
The engine runs on your machine — your games and analyses are never sent to a server.
Native on Apple Silicon and Intel. Paid once. Yours.
Playing on Lichess in the evening and chess.com on weekends? Régence imports the complete archive of both accounts in one click — clocks included. Then files them in a real game manager, on your disk: folders, smart folders, tags, search, saved views. Ten years of games, found in two seconds.
Knowing your opening isn’t enough — it has to hold under pressure. Régence imports your Lichess studies (public or private) and your PGN files, and gives you a real variation-tree editor, with comments.
One analyzed game is a lesson. A hundred analyzed games are a diagnosis. Régence’s dashboard crosses all your analyses: average accuracy, strengths and weaknesses by opening, traps you keep falling into, activity calendar. You no longer study at random — you study what actually costs you games.
Every move gets a clear label (Book, Mistake, Blunder…), every game’s report exports to PDF for the evening debrief, and the data stays on your Mac — your child’s too.
Photographic marquetry — walnut, oak, marble, slate. More than twenty-five piece styles. A dark mode made for evening study sessions. Sounds that feel right.

“Régence is built in France by an independent developer — me. A question, a problem, an idea? Write to me, I answer.”

Lichess is excellent — Régence starts where it stops: rich classification of every move (ten categories, not three), unlimited local analyses, a real game manager that gathers all your games (chess.com included), studies, repertoire and drilling. And your Lichess games import in one click.
Régence is built for online players roughly between 800 and 2200 elo. If you lose games without understanding why, it’s for you. Every move gets a clear label — no engine knowledge required.
Yes, structurally: engine analysis runs on your Mac, with no account and no server. Your games, analyses and statistics never leave your machine. Two limited, obvious exceptions: importing your games from Lichess/chess.com, and theory lookups (opening explorer, endgame tablebases) which query public databases position by position — never your games.
macOS 14 Sonoma or later, Apple Silicon and Intel. No Windows or iOS version — Régence is a native Mac app, by design.
Nothing disappears: your games, analyses and folders stay on your Mac. The app simply waits for your license to resume analyses.
2 Macs — say, the desktop and the laptop. Moving to a new machine takes two clicks.
No. They arrive automatically and are included in the €49. The changelog is public.
