# SharperSunday

> An AI co-manager that knows your roster. SharperSunday connects to your Sleeper or ESPN fantasy football league and reads your live roster, scoring rules, standings and leaguemate tendencies before it answers — trade verdicts, lineup calls, waiver targets, power rankings you weight yourself, and League Lore. SharperSunday works in your browser today — phone or desktop, nothing to install. Native iOS and Android apps are coming; we'll announce here when they're live in the stores. Bench is free (5 AI chats a week, 1 trade evaluation a day, 1 League Lore report a month, and your own team's Win Window). General Manager is $12.99/mo or $5.83/mo billed annually, with a 14-day free trial. Built on Claude AI. Dynasty player values are "Edge", SharperSunday's in-house model trained on real Sleeper trades.

## Definitions
- [Dynasty Trade Values](https://sharpersunday.com/learn/dynasty-values/): Dynasty trade values estimate what every player and pick is worth in a keep-forever league. SharperSunday's Edge model builds them from real Sleeper trades, not consensus vibes.
- [Superflex](https://sharpersunday.com/learn/superflex/): Superflex is a lineup format with an extra spot that can start a QB — which makes quarterbacks the most valuable assets in the league. Here's why it changes everything.
- [TE Premium](https://sharpersunday.com/learn/te-premium/): TE premium gives tight ends bonus points per reception, turning a thin position into a real edge. If your league has it, your rankings need to change.
- [Win Window](https://sharpersunday.com/learn/win-window/): Your win window is the dynasty phase your team is in — rebuilding, rising, or contending. Knowing it is the difference between a smart trade and a wasted one.
