Your fantasy league, modelled — not guessed at
nPortlytics Fantasy continuously models your entire Yahoo fantasy football league — every roster, the free-agent pool, NFL usage, projections, the remaining schedule and the playoff structure — and turns that model into specific actions you can check the reasoning behind.
Inside the app
The player pool, and who can take from it
Every surface states what it knows and when it last knew it — the week, the snapshot, and whether that snapshot is still fresh.
What it does
An operations console, not a dashboard
Dense tables, explicit state, auditable runs. The nearest relative in spirit is a logistics control tower.
League simulation
Simulates the rest of the season across the whole league to produce expected wins, playoff probability and championship probability.
Waiver and add-drop decisions
Ranks the available pool against your roster and your remaining schedule, including what a move denies an opponent.
FAAB guidance
Turns a bid into a number with its inputs attached, so you can see why it is that number and not a different one.
Manager intelligence
Models each manager’s observable behaviour — how they bid, when they drop, what they chase — because your league is played by people.
Breakout radar
Watches NFL usage rather than box scores, so a change in role surfaces before it shows up in fantasy points.
Trade analysis
Values both sides against your actual playoff path, not against a generic ranking list.
The one principle
Math decides. AI explains.
The numbers are deterministic
Every figure you act on — projection, expected wins, playoff probability, FAAB recommendation — comes from a versioned, reproducible model and is stored with the inputs that produced it. Run it again, get the same answer.
The assistant reads, it does not invent
The assistant explains those stored numbers in plain language. It never produces them. Ask it why, and it walks you through the model output rather than improvising a rationale.
Missing means missing
A missing fact is shown as missing, never replaced with a plausible guess.
Getting started
Connecting a league
Authorise Yahoo
Sign in through Yahoo’s own authorisation flow. Credentials are never handled by the app.
Pick your league
Your leagues are discovered from the account. Choose the one you want to operate.
First import
Rosters, transactions, settings and schedule are imported to build the initial model of the league.
Run the league
Refresh on demand, or let the weekly run pick up what changed and re-rank the decisions.
Questions worth asking first
Can it make moves for me?
No. It reads your league. It cannot make a transaction on your behalf. Writing transactions back to Yahoo is designed but deliberately not built, and turning it on would require explicit authorisation.
Which platforms does it support?
Yahoo Fantasy Football. Nothing else is supported today, and this page will say so when that changes.
Where do the numbers come from?
NFL usage and projection data, your league’s own settings and history, and a simulation of the remaining season. Each figure is persisted with its inputs, so any number can be traced back.
What happens when data is missing or stale?
A missing fact is shown as missing, never replaced with a plausible guess.
What does it cost?
Free for now. No card, no trial timer. If that changes it will be published here before it takes effect, not quoted privately.
