Someone had to build this.
Rikki spent five years writing software for other people's problems. Then he became a student again, studying MBM at the University of Strathclyde, and moved into shared housing.
The friction was not the people. It was the gap between shared life and the tools that were supposed to support it.

PRODUCT
Sunday Reset was built with AI. But not how you might imagine.
Three different AI models were used as sparring partners. They reviewed architecture decisions, ran independent security audits, and identified failure modes before users ever could. They argued with each other. Frequently.
Sometimes they were wrong. Sometimes brilliantly right. Every decision still came back to one person.
AI provided speed. It did not replace taste, persistence, or the work of deciding what this product should become.
Decisions that shaped the product
What it covers
Seven domains. One shared system.
Meals
Plan what the house can actually cook, not just what looks good in theory.
Groceries
Know what is needed, what is shared, and what should not be bought twice.
Expenses
Split costs in pounds with less awkwardness and fewer forgotten payments.
Chores
Make responsibility visible before resentment builds.
Safety
Keep important food and household safety details where people will actually see them.
Nutrition
Understand what you are eating without turning food into homework.
Chat
Polls, mentions, threads, and reactions. One place for the conversations that actually matter.
Who this is for
You already know which one you are.
The One Who Always Ends Up Organising
“Used to spend Sunday evening chasing five people for receipts. Now it just settles itself.”
The One With Dietary Restrictions
“Stopped having to explain their allergies in every new group chat. The house just knows.”
The One Who Hates Confrontation About Money
“Never had to send the 'can you transfer me' message again.”
If your house runs on group chats and good intentions, this is for you.
