Ask in plain English
Who do I start at flex? Is this trade fair? Who is worth a waiver claim? Mohn pulls your roster, your matchup and league-wide ownership for the question you asked.
Get an answer with receipts
Ranges instead of fake precision, and a panel showing which projections and live league data the answer was built from.
Start Player A or Player B at flex this week?
Player A, but it's closer than the season ranks suggest. Week 3 half-PPR has him at a 9.4 floor / 13.1 median / 18.6 ceiling against Player B's 7.8 / 12.4 / 20.2 — B is the higher-variance play if you need a ceiling to win.

Why you can act on it
A confident wrong number is worse than no number. The whole system is built around not giving you one.
Consensus, not one guy
Projections are blended from multiple published sources. Where those sources disagree, that disagreement becomes the player's floor and ceiling instead of being averaged away.
Value over replacement
Boards sort by VOR by default, because ranking on raw points puts a kicker above your WR2. Tiers are clustered off the same signal, so you can see where the real dropoffs are.
It says when it does not know
The coach may only state numbers that were retrieved for that specific question. If the data is not there, it tells you that instead of inventing a stat line. That rule outranks its personality.
