Best AI for fantasy football: 12 tools compared · Fantasy MCP servers compared · League Loom vs Flaim
Every sport
The same free connector covers every sport League Loom supports, so one setup can hold your NFL league and your NBA or NHL league together. Coverage depends on the platform: ESPN and Fantrax leagues work for football, basketball, hockey and baseball, and Sleeper leagues for football and basketball.
Start/sit, waivers, trades and matchups from ESPN, Sleeper or Fantrax NFL leagues.
Draft prep, points or category checks and trades from ESPN, Sleeper or Fantrax NBA leagues.
Draft prep, goalie coverage and weekly reports from ESPN or Fantrax NHL leagues. Sleeper hockey is not supported.

Use League Loom to list every league I have connected, with its platform, sport and season. For each one where my team is identified, give me one priority for this week from the returned roster, matchup and available players. Where no team is identified, give a short league overview instead. Flag any missing data and keep outside news separate. I will make any moves myself.

Why League Loom
Plenty of fantasy AI tools put extra leagues, deeper analysis, or faster refreshes behind a subscription. League Loom's connector is free end to end, with every league-data tool included.
Fantrax support also means keeper, category, and salary-cap managers are not left out. Ask who to drop for a streaming defense, request one weekly digest across ESPN and Fantrax, or check Sleeper FAAB before waivers.
Every answer uses the same free connection, with no feature held back behind a paid tier. Fair-use request budgets apply.
FAQ
Yes. The MCP connector you add to Claude or ChatGPT is free, with no subscription and no per-league fee. Fair-use request budgets apply.
League Loom is just the connector that feeds your live league data to whatever AI tool you already use. It doesn't charge for that access.
Current connector tools use league data to give advice; no write-action tools are registered today.
No. Every connector feature and every connected ESPN, Sleeper, or Fantrax league uses the same free access. There is no per-league fee or premium unlock for weekly digests, waiver rankings, or other connector tools.
There isn't one. The connector authenticates with your leagues over OAuth and brings live data into the AI client you already use. It does not run ads, sell your data, meter connector tools, or hide features behind a subscription.
Not for Claude: its free plan allows one custom connector, which is enough for League Loom. ChatGPT custom apps need developer mode, which OpenAI offers on Plus, Pro, Business, Enterprise and Education accounts on the web. League Loom itself adds no cost either way.
League Loom and Flaim are free connectors with no paid tier. Other fantasy AI tools range from free access with daily, credit or feature limits to paid plans. The list on this page gives each product's own pricing with the date it was checked.
Add the connector on a computer: claude.ai or Claude Desktop, or ChatGPT on the web. What works on a phone afterward depends on the assistant. In Claude, a connector added on the web or desktop is also available in the Claude iOS and Android apps, so you can ask about your leagues from your phone. In ChatGPT, custom apps like League Loom currently run only on the web, not in the ChatGPT phone apps. If you start on a phone, use Send to my computer to email or message yourself the link and finish later.

Ready in two minutes
Free connector, private setup, and 19 tools that retrieve or analyze your league data, plus a share link for your league chat when you ask. No tool changes your lineup or roster.
