Built for category leagues
The best AI for fantasy basketball is one that knows your live roster and scoring format — League Loom connects your ESPN, Sleeper, or Fantrax NBA league to Claude and ChatGPT, and it's one of the only options that handles Fantrax category leagues.
Punt builds and 9-cat math fall apart when the AI can't see your roster. League Loom reads your live team, so advice respects which categories you're chasing.
It covers ESPN and Sleeper NBA, plus Fantrax — the deep-league platform most AI fantasy tools don't support.

In Claude, ChatGPT, or any MCP tool, add a custom connector and paste the League Loom URL — leave Client ID & Secret blank.
A quick wizard finds your leagues and lets you pick your team in each. No API keys.
Ask about your roster, waivers, matchups, and more — in plain language, across every league.

Fantasy basketball lives in category math, and most AI tools can't see your roster — let alone a Fantrax league. League Loom is free, open source, and read-only, connecting ESPN, Sleeper, and Fantrax NBA leagues to Claude and ChatGPT so advice fits your actual scoring format and live team.
