What is it?

chatless is a desktop AI chat client that connects to cloud providers such as OpenAI, Anthropic and DeepSeek, or to local models run through Ollama and LM Studio. Conversations and data are stored on the user's own machine.

Beyond basic chat, it parses PDF, Word and Markdown documents, supports image understanding with Vision models, and includes a local RAG knowledge base that uses vector retrieval. It also integrates MCP for third-party tools and offers a prompt library that can sync across devices through WebDAV.

The app is built with Tauri 2.0, Rust and SQLite on the backend, and Next.js 15 with TypeScript for the interface. Installers are provided for Windows, macOS and Linux.
