OpenWorker is a free, open-source AI agent that runs locally on your computer and works across tools like Slack, email, calendar, GitHub, and CRMs to complete tasks end to end. Users describe a desired outcome and OpenWorker executes the necessary steps, producing finished documents, messages, or calendar updates. It supports any model provider including OpenAI, Anthropic, Gemini, and local models via Ollama, using the user's own API keys. Before taking consequential actions such as sending emails or posting to Slack, it pauses for user approval, keeping the user in control throughout.
