Witsy

Witsy is a desktop AI assistant and universal MCP client that brings multiple AI providers into one application. It supports models and services from providers such as OpenAI, Anthropic, Google, Mistral, Groq, DeepSeek, and Ollama, allowing users to work with different models through one interface. Witsy also supports local document conversations through retrieval-augmented generation, image and video generation, speech-to-text, voice conversations, and AI commands that can be triggered while working in other applications. Its MCP support allows compatible external tools and services to connect with supported models. The app follows a bring-your-own-key approach while also supporting local models through Ollama, making it useful for users who want flexibility across cloud and local AI systems.
