# Split expenses

Who paid for what, how it’s split and who owes whom, for roommates, couples or a trip. Say what you paid, and your assistant keeps the balance.

## An example

**You:** I paid the electricity bill, 840, split three ways. And 45 for cleaning supplies, just between me and Sara.

**ADoor:** Added 2 entries to Shared costs

**Shared costs**

| Date | What | Amount | Paid by | Split |
| --- | --- | --- | --- | --- |
| Oct 20 | Electricity | 840 | Erik | Erik, Sara, Jonas |
| Oct 20 | Cleaning supplies | 45 | Erik | Erik, Sara |

## What you can ask later

- “Who owes whom right now?”
- “How much have we spent on electricity since the summer?”
- “What did I pay for that hasn’t been settled?”
- “Mark Sara’s transfer as settled.”
- “Chart our shared bills by month this year.”

## Who can see what

- **Everyone in the group** adds what they paid and reads the balances, from their own assistant.
- **Nobody can edit someone else’s entries**, if you set it up that way. Every change keeps who made it and the before and after.
- **Your personal budget** stays in your own space, out of the shared one.

## How it compares with Splitwise or Tricount

Splitwise and Tricount handle the payment side: simplified debts, currencies and settling up through a payment app.

ADoor fits when shared costs are part of a bigger picture, like house bills next to the chores rota. Anyone adds in a sentence, the history shows recent changes and who made them, and your assistant can answer any question about the balance.

## How to start

1. Sign in to ADoor, then add it to an assistant like ChatGPT, Claude, Grok or Cursor through MCP.
2. Tell it: “Track our shared costs: date, what, amount, paid by, split between, and settled. Invite my roommates.”
3. Let each person edit only the entries where Paid by is their name, one grant per person.
