ThinkOS is an open-source, local-first application that serves as the user interface layer for AI agent servers. Where frameworks like OpenClaw provide the agent engine, ThinkOS provides the experience — a unified dashboard for managing agents, tasks, and personal knowledge, with your data stored entirely on your own device.

Built for users who want the full power of modern agentic AI without sacrificing privacy or control, ThinkOS supports any OpenAI-compatible model provider (Ollama, Claude, GPT, and more) and features a sandboxed plugin architecture that prevents third-party extensions from exfiltrating your data.

ThinkOS is free, self-hosted, and open source. Contributions welcome.
