Claudia Faith was spending Sunday evenings writing Substack Notes and dreading it. Ninety minutes minimum, often more. She knew she needed to fix this, but the problem felt bigger than just finding a faster way to write.
She started analyzing her own Notes performance data. What she found stopped her cold. Most of what she was writing by intuition was wrong. The formats she thought performed well weren’t the ones actually driving new subscribers.
She built the 21 Notes Agent to pull performance data first, weight the topic mix around what actually converted, and then generate 21 Notes in her voice. It wasn’t about writing faster, it was about writing smarter, starting with what the data actually said.
The week after she deployed it, she redirected her Sunday evening to a coaching call that paid $1,200. The Notes still went out. They got better. Enjoy.
Problem This Skill Solves
Creating a week of Substack Notes manually takes 90 minutes or more, runs on gut feel, and produces inconsistent results. Most creators don’t know which formats actually bring in new subscribers, so they keep writing what feels right and wondering why growth stalls. This skill starts with your performance data, not your assumptions.
