When it saves new notes, Mentor compares them with older ones and records where they disagree. When two notes disagree and it bears on your question, Mentor names both with their dates and asks which holds.
What it does
Each time Mentor writes new notes to memory, it checks them against what it already holds and records where they disagree.
When two notes you gave Mentor disagree and it bears on the question, Mentor names both with their dates and asks which holds. It is told to advise from the newer note when your newer position replaced the old one, and to mention the change only when it matters.
Why
Tell Mentor in January that you ruled out tiered pricing and in June that you shipped three tiers. It shouldn't answer from whichever came up first without telling you the other exists.
How to use it
Open the Mentor guide in your dashboard, or start a trial to try it.
