League Coach
Command Center
A static-site cockpit for Riot IDs, live Riot API pulls, recent ranked review, champion rotation, and copy-ready coaching prompts for Krahnie, ChatGPT, Claude, or any other AI coach.
Summoner cockpit
Your API key stays in this browser’s localStorage and is only sent to Riot as an api_key query parameter. This static page does not contain or publish your key.
Copy-ready AI coach prompt
Collapsed by default so profile scans stay readable. Open it when you want to paste your Riot snapshot into ChatGPT/Claude without giving it the API key.
