What would SharperSunday say?
Tap a real trade — see the sharper side.
Customize Rankings
Every other fantasy tool blends production and market hype into one ranking and tells you to trust it. SharperSunday separates them and hands you the dials. Slide the weights for production and youth — find the players your leaguemates are overpaying for, and watch your power rankings reorder live.
Your dials, your formula — Strongest Lineup, Roster Value, Youth, and Draft Capital, each on its own slider. Tilt toward youth and draft capital, and the board re-ranks around it.
League Intelligence
Connect your Sleeper account once. Your advisor doesn’t just pull your roster — it reads the entire shape of your league before it answers a single question. Every quirk, every setting, every leaguemate’s pattern is baked into the take.
“Should I start my TE or my third WR in the flex this week?”
Start the TE. Your league runs TE premium (+1.5 PPR at the position), so even a middling target share clears your WR3’s ceiling on points alone — and your flex spot rewards floor, not upside, given where you sit in the standings.
“What’s my TE actually worth if I shopped him?”
His Edge value jumps in your league vs. a standard one — TE premium plus your Superflex setup move him up a tier. A contender in your league would pay a bit over market; a rebuilder won’t bite. I can flag which leaguemates are short at TE.
Roast with Receipts
Fantasy is a group chat with a sport attached. Connect your league and get AI roasts grounded in real trade data, leaguemate tendencies, and season history. Every jab is backed by receipts: who fumbled that trade, which manager panics at 26, who gets lucky on waivers. Use the material to win trades before they see it coming.
Built by a fantasy player
I’m Mason. I’ve played fantasy since 2006 — redraft and dynasty, usually three leagues, usually the most active trader. I built SharperSunday because everyone who cares about their league deserves reads tuned to their actual teams, not generic advice. If something’s off or you have an idea, reach out — I read every reply and build the next version around it.

FAQ
Yes. SharperSunday reads your league’s full configuration from Sleeper — scoring (PPR, half-PPR, TE premium, custom TD and yardage bonuses), lineup format (flex, superflex, IDP), and size (8–16 teams, taxi, IR). Whatever your commissioner set up, the advisor accounts for it. Sleeper only — ESPN, Yahoo, and MFL aren’t supported yet.
Generic LLMs train on a snapshot and freeze — ask one about a trade and you’ll get last year’s depth chart and scoring rules that aren’t yours. SharperSunday pulls your live roster, your league’s actual settings, and current NFL context every time you ask.
Yes. SharperSunday uses Sleeper’s public, read-only API — no password required, and the app can’t make trades, drop players, or change anything in your league. You enter your username, it reads what’s already public (rosters, transactions, settings), and that’s it. Nothing is sold or shared with third parties.
Both work. SharperSunday detects your format from Sleeper and tunes the advice — redraft leans into production and matchups; dynasty layers in age, draft capital, and your win window. Same chat, waivers, and trade tools either way.
