OpenDuet

OpenDuet is an open-source proactive AI agent that executes tasks autonomously and prompts users for review.

OpenDuet is an open-source proactive AI agent built on OpenBot and CopilotKit that manages workflows, reads Gmail and Google Calendar, and operates in its own browser and shell environment. It provides a morning brief, sorts incoming communications, and handles scheduled work while keeping humans informed. Before performing sensitive actions like sending messages, making payments, or deleting data, it requests explicit user approval. Users can host it themselves, choose models such as OpenAI or Anthropic, and connect tools via Model Context Protocol. It is designed for developers and teams who want a self-hosted assistant that securely automates tasks while maintaining strict oversight.
