Analysis previews use an isolated board. Local moves, comments and Undo remain available while a provider is busy or fails.
Offline mode uses authored illustrative numbers and protocol fixtures. No engine computed these predictions, and no network request is sent.
Manual mode sends nothing automatically. Analyze position captures a query below. Pass that one line to your configured KataGo analysis process, then paste its final stdout response. Configure Black reporting and preventCleanupPhase=true. Credentials, engine setup and connections remain host-owned.
