Live data beats stale GPTs
The best AI tool for fantasy football is one that reads your actual roster instead of guessing at generic advice. League Loom connects your ESPN, Sleeper, or Fantrax league to Claude, ChatGPT, and other MCP-capable AI clients, so the AI can see your real starting lineup, standings, and matchup before it answers. It's free with no paid tier, read-only (it never sets your lineup, makes a trade, or claims a waiver for you), and sign-in uses OAuth 2.1 with PKCE instead of pasting in an API key.
League Loom connects your real leagues (ESPN, Sleeper, and Fantrax) straight into Claude AND ChatGPT, so the AI answers from your actual roster, not generic rankings.
It's the only connector that brings deep-league Fantrax formats into the chat alongside the big two, and it reads live data: injuries, byes, and waiver availability update in real time.

Why League Loom
Most "fantasy football AI" tools fall into two camps: a generic chatbot you have to re-brief every week by pasting in your roster, or a single-platform app that only covers one league host. League Loom takes a different approach: it connects directly to your live ESPN, Sleeper, or Fantrax league through OAuth, so the AI you're already using can pull your actual roster, standings, matchups, and available players on demand. That means questions like who to start at flex, which waiver-wire running back is worth a claim, or whether anyone on your bench is on a bye get answered from your current data instead of last month's memory or league-wide rankings that ignore your roster. It supports all three major NFL platforms, including Fantrax, which few competing tools handle at all. It won't set your lineup or submit a waiver claim for you: it reads league data and explains it in plain language, and the decision stays yours. There's no paid tier to unlock more features.
