How to connect Lichess to Claude Code, ChatGPT and any AI agent

Yes, Claude, ChatGPT and other AI agents can work in your Lichess account. Cotlet.dev connects your own signed-in Lichess account to any AI agent, so you can ask in plain words and the AI accepts team join requests and sends updates to your team for you.

What you can ask

Accept the join requests from tom_k and anna_plays to my "Riverside Chess Club" team.

Show me all pending join requests for my team and who sent them this week.

Send a message to all members of "Riverside Chess Club": our blitz arena starts Thursday at 7 pm.

Accept every join request from today, then tell the team that 4 new players joined.

Message my team that Saturday's lesson with coach Maria moves to 10 am.

Connect in 2 minutes
