3 Things AI

AI chooses the three highest-impact tasks.

Picks the three, from everything captured, based on what is due, what is blocking others and what was avoided yesterday. The user can override it, and the app learns from every override.

The market

Proven marketTask and daily planning
50M usersat Todoist, of whom roughly 300,000 pay

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

These viewers capture more than they can process and then choose badly under pressure, usually picking whatever is loudest. They are comfortable handing judgement to a tool - the content is full of AI delegation. Choosing the three is a decision they would rather not make each morning.

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.
