Public sources, your databases, your chess workspace

Grimoire

Collect the games that matter to you: import PGN files, including compressed archives, or use public connectors such as Lichess broadcasts. Then build your databases and explore them locally.

Localexploration and analysis

Your games, straight from the source

From public sources to a database ready to explore

Grimoire does not impose a bundled corpus. You choose the public sources that matter to your work, import them into your own databases, then explore and analyse them locally.

Universal PGN import

Import PGNs exactly as you receive them, whether individual files or compressed archives, with no manual preparation.

Public connectors

Retrieve games directly from a public Lichess broadcast. More public sources, including TWIC, will follow.

Position explorer

Move tree, statistics and matching games stay synchronised as you navigate.

Player preparation

Build a player’s White or Black repertoire tree from the games you have collected.

Local analysis

Install a free public UCI engine such as Stockfish, then configure its lines, depth and memory in Grimoire.

Controlled databases

Organise, merge and reset your databases while retaining control of their files and provenance.
