Weekly review
Four of five habits kept this week.
The problem
I was tracking my day, goals, habits and money across a pile of apps. I wanted one place that knows all of it.
What I built
- Today: a live plan for the day that re-plans itself when things slip.
- Money Desk: budget, sinking funds, savings goals and a debt-free date estimate, with an AI money companion.
- A weekly tracker and an AI-written weekly review.
- Intel: daily suggestions, live scores and the channels I follow.
- Journal, habits and fitness tracking.
How it’s built
Next.js 16 with Prisma on Postgres, deployed on Railway. Claude and Groq power the planning and money features. The interface uses Radix UI and Recharts.
