How to Connect Your Fantasy League to AI

You can connect your ESPN, Yahoo, or Sleeper fantasy leagues to Claude, ChatGPT, Perplexity, or Gemini using Flaim. Setup takes about 5 minutes. Once connected, your AI assistant can access your real league data: rosters, standings, matchups, free agents, and transactions. All read-only.

Choose your platform

ESPN

Requires the Flaim Chrome extension to sync your league credentials. Supports football, baseball, basketball, and hockey.

Yahoo

No extension needed, just sign in with Yahoo. Auto-discovers all your active leagues. Supports football, baseball, basketball, and hockey.

Sleeper

Just your username, no extension, no OAuth to Sleeper. Currently supports football and basketball.

Connect your AI assistant

After connecting your fantasy platform, add Flaim to your AI assistant. You'll need this server URL:
