When to choose:
  • You want a self-hosted personal AI assistant that lives inside 20+ messaging apps you already use (WhatsApp, Telegram, Slack, Discord, iMessage, Signal, Teams).
  • You want your state, memory, and credentials kept on your own machine, with optional companion apps on macOS, iOS, Android, Windows, and Linux for voice and screen actions.
When to skip:
  • You want a zero-ops cloud-hosted chatbot without managing a local Node.js 24+ Gateway and API keys.
  • You only want a desktop multi-provider chat GUI on your computer rather than messaging-channel gateways; Cherry Studio is simpler for desktop chat.
