AI Weekly Life Planner

Build realistic weeks around work, deep work, fitness, learning, and commitments.

What a v1 does5 features
  • A week planned against hours actually available
  • Fixed commitments in first, everything else fitted around
  • Exercise and learning treated as commitments, not leftovers
  • Automatic replan when a day goes wrong
  • Weekly review of planned against actual

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 $9 a month this is priced below both.

Why this audience

These viewers plan aspirational weeks and lose them by Wednesday, then blame discipline. The content pushes systems over willpower. Planning against the hours that actually exist is the correction they are primed to accept.

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.
