Pricing Details
Witsy AI is completely free and open-source with no internal subscription plans or in-app purchases. Users simply download the desktop app and connect it to their preferred large language model provider (like OpenAI, Anthropic, etc.) using their own API keys. While Witsy itself is free, usage costs depend on the connected provider’s pricing model. The app supports macOS, Windows, and Linux, and can be installed via package managers like Homebrew. With no ongoing fees, users retain full flexibility and cost control by choosing how and when they use different AI models.
