AyuutoCase study
A web app for running community savings circles.

TheProblem
Savings circles are how millions of people save: a group pays in the same amount each round, and each round one member takes the whole pot. They run on trust — and usually on a spreadsheet and a group chat.
That makes it hard to see who has paid, whose turn is next and what's still owed. Ayuuto replaces the guesswork with one shared, transparent record.
TheProduct
Members create or join a circle, set the contribution amount and frequency, and follow a turn tracker that shows the payout order and progress. Contributions are recorded and approved by the circle's admin, so everyone sees the same numbers.
Around that sit accounts, profile and settings pages, public and invite-only circles, AI-generated reminder messages, and a blog and guides that explain how savings circles work.

What itDoes
- 01
Circles and turn tracking
Create a circle with its amount, frequency and size, invite people or let them request to join, and see the payout order at a glance.
- 02
Contributions with approval
Members record each payment; the circle's admin approves it. A full history keeps the record straight across every circle.
- 03
AI-written reminders
Personalised contribution reminders generated server-side with Google's Genkit and Gemini.
- 04
Accounts and protected pages
Firebase Authentication with session-based route protection, so app pages are only reachable when signed in.
- 05
Shared pots (beta)
An admin-only beta for pooled pots with tracked withdrawals and repayments.
- 06
Content for search
A blog and guides explaining savings circles, plus a sitemap and per-page metadata.
