modelbrain setup claude-code or modelbrain setup cursor in a terminal. See Claude Desktop, Claude Code and Cursor.macOS on Apple Silicon (M-series) Macs, Windows 10 and 11 on x64 and ARM64, and Linux on x86_64 and aarch64 as a command line package. Intel Macs are not supported.
Yes. It is a command line package with no tray icon and no window, so you set up assistants with the modelbrain setup command instead of the setup guide. It works with Claude Code and Cursor directly, and with ChatGPT through the relay client.
No. Local use needs no account, no card and no licence key. An account is only needed for ChatGPT, which connects through a hosted relay, and for the paid sync and team plans.
Connect ModelBrain to the assistant you actually use.
