WeSplit.Fun

Shared expenses, now in your AI chat

Just say who paid. We’ll do the math.

Type or dictate to ChatGPT or Claude: “Beer, €48, I paid, split with Anna and Max.” WeSplit.Fun adds it to your group, splits it fairly and shows who owes whom. Prefer tapping? Everything works in the app too.

Create a free group✨ Connect ChatGPT or Claude

Choose a family, travel or shared-home example. No sign-in needed.

Ask like you’d ask a friend

Connect WeSplit.Fun once, then type or talk to ChatGPT, Claude, Codex or any app that supports MCP, in any of our 15 languages.

  • “Who owes whom in our Oktoberfest group?”
  • “Max paid me back £20”
  • “How much did we spend on food this week?”
  • “Create a group “Lisbon” in euros with Sam and Alex”

To speak, tap the microphone in the message box and dictate.

You stay in control: the assistant only gets the access you allow, every change shows in the group under your name, and no money ever moves.

  3. See who owes whom

    Check balances, share the group link and record repayments when money changes hands.

We Split Fun in 40 seconds

Remind friends to settle up

Next to money you're owed, tap Remind and send a friendly, ready-made message with the amount and a link where they can settle up.

Your spending, clearly

Filter by person, category and day. See what you paid as well as your share of the costs.

Cash is not another expense

Record money passed between friends as a transfer. It affects balances without inflating spending totals.

A browser is enough

Open the app on your phone or computer. You can also add it to your home screen.

Does everyone need to register?

You can add people to a group before they sign up. Share its invitation link so they can join and claim their participant profile.

Does the app send money?

No. It records expenses, transfers and repayments. You pay each other separately, then record the payment in the group.

Copy link
Can I split expenses in different currencies?

Yes. Add expenses in supported currencies. The app keeps balances by currency instead of silently converting your money.

Does it work with ChatGPT and Claude?

Yes. Connect WeSplit.Fun once and ask in your own words: who owes whom, add an expense, record a repayment. The assistant only gets the access you allow, and you can disconnect it in your profile at any time. Step by step: wesplit.fun/ai.
