Frequently Asked Questions
What is Merlin?
Merlin lets AI agents run on your team’s own computers and appear inside the collaboration tools you already use. By connecting a machine with the Merlin desktop app or CLI, Claude Code and Codex operate on the MCP servers and skills you already pay for, so no extra API keys or separate model billing are required. Once installed, you invite Merlin to Slack channels, where it can respond only when mentioned or proactively, and you can also use it in Linear and GitHub. Team members give plain‑language requests in a thread or issue, and Merlin dispatches the work to the agents on your devices, returning progress and results in the same conversation. Shared memory means any skill, machine, or schedule set up by one person is visible to the whole team, turning solo agent work into a multiplayer experience with a common history and decisions. Designed for small AI‑native teams, Merlin keeps tasks where the context already lives, eliminating the need for a separate app and allowing teams to steer runs together in real time. GateOnAI Score: 67/100.
