SharperSunday · Feature
Your league's history, written up with receipts.
AI-written recaps, season stories, and trade retrospectives built from your league's real Sleeper history.
The problem
Every league has its stories — the lopsided trade, the choke job, the dynasty everyone swears was rigged. But they live in fuzzy group-chat memory, and the loudest manager always remembers it in his own favor.
Trying to recap a season yourself means digging through months of transactions and box scores. Nobody does it, so the lore fades and the trash talk runs on vibes instead of facts.
How SharperSunday does it
SharperSunday reads your league's real history from Sleeper and writes it up — weekly recaps, full-season stories, historical deep-dives, and trade retrospectives, in a voice that sounds like your sharpest leaguemate.
Every claim comes with the receipt: the actual trade, the actual score, the actual standings. It's roast material you can't argue with, and it's one tap to share the report with the whole league.
Why it works
Four report modes
Weekly recaps, season stories, historical deep-dives, and trade retrospectives — all drawn from your league's real data.
Receipts, not vibes
Every story is backed by verified Sleeper history — the real trades, scores, and standings — so the trash talk holds up.
Built to share
Publish a report and share it with your league in one tap, so the lore lands in the group chat where it belongs.
