What is Fantasy Agent?

Fantasy Agent is a gaming AI assistant tool. An AI fantasy football general manager for Sleeper and ESPN leagues. It emails weekly lineup, waiver and trade calls, follows a custom GM philosophy, and grades its own decisions against real outcomes, with billing limited to August through December.

Fantasy Agent is an AI general manager built for fantasy football leagues hosted on Sleeper and ESPN. Rather than acting as a draft-day helper, it works the whole season: each week it sends lineup, waiver and trade recommendations by email before your league's deadlines, then logs what it called and grades those calls against what actually happened. The result is a running record of decisions rather than a single burst of advice in August. The setup is deliberate and one-time. You sign in with an emailed link, look up your league by Sleeper username or ESPN league ID, and prove you control the team by temporarily adding a short verification code to your team name. From there you answer up to 24 optional questions across six topics, which build the GM philosophy the agent follows: whether you prefer a safe floor over upside, how aggressively it should bid FAAB, and similar rules. You can skip all of it and add preferences later, and the philosophy can be edited at any point. Each additional league carries its own philosophy or inherits your main one. The dashboard is the part that distinguishes it from a chat prompt. It shows hit rate broken down by how confident the agent said it was, a decision mix of lineup, waiver, trade and flagged activity, and an activity log you can filter. Guardrail flags mark calls that were held for your review rather than pushed through. A live demo replays a sample season week by week so you can judge the reasoning before paying. It suits season-long managers in competitive Sleeper and ESPN leagues who want a consistent process more than a one-off cheat sheet. It is not a draft simulator, not a DFS optimizer, and not a best-ball tool. Yahoo leagues cannot be connected yet because Yahoo requires OAuth rather than a public league page, and the agent has no Yahoo data adapter, so that platform is listed as roadmap only.

  2. 2Find your league
    Choose Sleeper or ESPN, then look it up by Sleeper username or by ESPN league ID or URL. The league must be publicly viewable, which the league manager enables in settings.
  3. 3Verify team ownership and subscribe
    The site gives you a short code to paste into your team name temporarily, then checks it. Payment is handled by Stripe, and off-season signups wait until August for the first charge.
  4. 4Teach the agent your philosophy
    Answer up to 24 optional questions across six topics, then set where reports go and when they are sent. Skipping the questions gets you started immediately and preferences can be added later.
  5. 5Review the demo and the how-it-works page
    Before or after signing up, replay the sample season week by week to see the calls, the reasoning behind them and how they were graded against outcomes.
