How does Monty learn my voice?

From the drafts you edit before approving. When you change a phrase, Monty stores that as a correction and feeds it back into how it writes, so it steers away from the phrasings you keep rewriting. Approving a draft unchanged tells it nothing was wrong — editing is what teaches it. Expect the first drafts to need the heaviest edits while your voice profile calibrates.

You can recalibrate at any time from Settings → Voice if your style or role changes — stating a preference there is faster than teaching it by edits.
