Description
openTag is an innovative open source AI coworker designed to integrate seamlessly with Slack and Lark. It enables users to run AI coding agents directly on their own computers, utilizing existing subscriptions or API keys from providers like Claude, Codex, or Pi. This setup ensures that all processing occurs locally, maintaining user privacy and data security. openTag supports Mac and Linux systems and is free to use, with users only needing to cover the costs of their AI subscriptions.

The platform is designed to be highly flexible and customizable, allowing users to mention openTag in a thread to initiate tasks. The app then delegates the request to the user's computer, where a background program executes the coding agent. The results are sent back to the thread, providing a seamless workflow. openTag's architecture supports team collaboration, enabling agents to serve entire channels and hand off tasks to one another.
openTag's privacy policy emphasizes that its servers do not store conversations, code, or memory. Instead, team memory is managed through a Context Tree, a markdown-based system hosted in a user's GitHub repository. This approach ensures that data remains under the user's control.
The platform currently supports Slack and Lark, with plans to expand to Teams and Discord. It also offers extensive integration capabilities, connecting to over 1000 popular services through MCP connectors. These include tools like Notion, Google Drive, Gmail, and more, allowing users to enhance their workflows with ease.
openTag is particularly beneficial for developers, teams, and organizations looking for a customizable, secure, and cost-effective AI solution that integrates with existing tools and workflows.
