AIChessGM helps you build a real opening repertoire from your own games. Create a transposition-aware Opening Tree, add engine evaluations only where it matters, use the Features pane to turn positions and games into structured coaching, and train your lines with structured practice tools.
AI features are optional. AIChessGM is first and foremost a modern macOS chess database and repertoire system.

Privacy: AI features are optional and disabled by default. Provider credentials stay in local app preferences on your Mac; content is sent only when you use a configured cloud feature. Read the privacy policy.
Website operations: Download links may use server-side counting for release statistics. Optional newsletter signup is separate from the app.
Support: Existing customers can email support@aichessgm.com. General and pre-sales questions can go to info@aichessgm.com.
Commercial terms: Review the license FAQ, 30-day refund policy, and license agreement. Purchase is handled by Lemon Squeezy through its secure hosted checkout.
Existing preview users keep their displayed trial expiry, including September 20, 2026 where applicable. Installing the commercial update preserves the expiry already shown to existing testers; it does not restart their trial. A paid activation preserves full access after that expiry. Without activation, Restricted mode keeps local files available to open, view, and export; editing, analysis, AI, and training require a license. See how to purchase and enter your license key.
Read the main AIChessGM user guide, open the dedicated Repertoire Builder guide, or use the optional remote Leela setup guides.
Optional: This remote-engine package is not required to install or run AIChessGM itself. AIChessGM works on its own without any Vast.ai, Tailscale, or Leela server setup.
Bridge source included: The setup package now includes the Go source for the Leela communication/startup layer, so you can build the bridge for Windows, macOS, or Linux. The bundled prebuilt bridge binary is Linux x86_64 only.
Fresh Vast container recovery: The packaged Vast bootstrap now auto-installs tailscale when the base Jupyter image is missing it, so a persistent /workspace volume can restore the service on the next start with much less manual recovery.
