The problemToo many places, no daily view.
The problem
My information lives in too many places:
- School updates get lost in email.
- My meal plan sits in Notion, unopened.
- Subscriptions renew before I notice.
- Appointments hide in my calendar.
No tool tells me what needs my attention today.
The goalOne place, no new app.
The goal
One place that shows me what matters, using tools I already have. No new app to install or learn.
The solutionAn assistant in WhatsApp.
The solution
An assistant inside WhatsApp. It reads my email, calendar and Notion, then sends me what I need to know in one chat.
It owns no data. Everything stays in the original tools. If I turn it off, nothing is lost.
Key decisionsFour rules it follows.
Key decisions
- WhatsApp, not a new app. I already use it all day.
- Ask before acting. It can read and remind on its own. Sending anything needs my approval.
- Connect, don’t replace. It works with my existing tools.
- Start small. Build one useful feature first, then grow.

Measuring successFour signals to watch.
How I’ll measure success

- I read the brief most days.
- Most drafts need no edits.
- No important item is missed.
LearningsStart where people already are.
What I learned
The best AI product isn’t always a new app. Putting help where people already are makes it easy to use from day one. Starting with one small, real feature taught me more than planning everything at once.
