September Planning AI

AI planner for goals, tasks, plans, and schedules.

For the annual reset that never survives October: goals turned into a schedule the year can actually hold, with the plan revised when it slips rather than abandoned.

What a v1 does5 features
  • Goals broken into terms, months and weeks
  • A schedule built around commitments already in the calendar
  • Replanning when a week is missed, rather than a reset
  • Progress reviewed monthly against the original intent
  • One page showing the whole year at a glance

That is about 0.6% conversion at the most successful independent task manager there is. Motion went from $2M to $50M in under two years charging $19 to $34 a month, and Sunsama charges $16 to $20. At $8 a month this is priced below both.

Why this audience

This audience responds to structured, frameworked advice - the content is built on named systems rather than vibes. They set goals seriously and lose them to a schedule that never existed. A plan the year can actually hold is the practical form of what they already consume.

Before it can launch

No licence, certification or data agreement stands between this and a launch — app-store review and an ordinary privacy policy aside.

Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.

Is this the one for your audience?

We fund it, build it, and run it. You bring the audience and take a share of the revenue. Nothing to pay and nothing to build.
