Merlin

Merlin is an AI collaboration tool that brings Claude Code and Codex to Slack, Linear, and GitHub.

Merlin brings AI agents into the collaboration tools your team already uses, allowing multiple people to work with agents together in threads. The software runs agents on your team's own computers using your existing Claude and Codex subscriptions without separate API keys. It integrates with Slack, Linear, and GitHub to let teams ask questions, delegate issues, and view progress in one place. Features include shared skills, recurring schedules, workspace memory, and access controls for devices and skills. It is designed for small AI-native teams looking to share context and decisions across tasks.
