AI Writing App for Coaches (Keeps Your Voice)
The best AI writing app for coaches who want the content volume of a team, without sacrificing the voice that's unmistakably yours.
In plain English
Coaches who want as much writing as a whole team would produce, while still sounding like themselves, are who Jason Zook built this app for. It studies the coach's voice and older posts, then drafts new pieces in formats that have already worked, and a person edits the draft before it is published. Coaches pay a subscription because producing that much writing alone is hard. The app is shown off by posting its own results. The AI does most of the drafting and the billing, while Jason checks quality, helps coaches, and handles unusual cases.
