Works in ChatGPT, Claude & Muse

Split bills.
Stay friends.

Snap the receipt, tell your AI who had what. NutSplit does the math, your friends confirm their share, and the ledger lives in your own Google Sheet.

Free. No app to install. No daily limits.

Sent to Sean to confirm his 2 items.
How much does Sean owe me this month?
Sean owes you $248.60 across 6 bills. 1 bill is still waiting for him to confirm.

Three steps. Zero spreadsheets to touch.

1 · Tell your AI

Send a receipt photo or just say “dinner $84, split with Amy.” Your AI reads it and calls NutSplit.

2 · Say who had what

One line does it: 3,6: Sean · 4: me · rest: everyone. Or tap items on a list. Percent splits work too.

3 · Friends confirm

Everyone checks their own items — in their AI or at app.nutsplit.com. No surprises, no “wait, I didn’t have that.”

Built for how roommates actually split

🧾 Item by item, not ÷ 4

Groceries where one thing was for a friend? Tax only on some lines? NutSplit handles item-level splits, tax and tip, and scales to the receipt total to the cent.

📊 Your data, your Sheet

The ledger is a Google Sheet in your Drive — readable tabs per month, balances, items. Members get view-only access. You can always walk away with it.

🏠 Rent, internet, hydro

Set fixed costs once. Fixed amounts post themselves each month; for bills that change, your AI just asks “how much was Hydro?”

🗓️ Monthly or trip

Close the month when everyone’s confirmed and get the fewest transfers to settle up. Trip groups archive themselves when you’re done.

✅ Both sides confirm

Nothing counts until the person who owes agrees. Disputes go back to the payer with a suggestion, not an argument.

🔁 Leaving Splitwise?

Upload your Splitwise group export. We match names, archive the history and carry over who owes whom.

Add NutSplit to your AI

In Claude: Settings → Connectors → Add custom connector. In ChatGPT: turn on Developer mode under Settings → Apps, then Create. In Muse or any other MCP client, add it as a remote MCP server. Paste this URL and sign in with Google:

Friends without an AI connector can still confirm everything at app.nutsplit.com.

Questions

Is NutSplit free?

Yes. NutSplit is free, with no daily limits and no ads.

Do my friends need ChatGPT, Claude or Muse?

No. Only the person adding bills needs an AI with the NutSplit connector. Everyone else can confirm their items, see balances and settle up at app.nutsplit.com with a Google account.

Where is my data stored?

Bills live in a Google Sheet in the group owner's Google Drive. NutSplit only keeps the account and group details it needs to run, like names, emails and which Sheet belongs to which group.

Can NutSplit see the rest of my Google Drive?

No. NutSplit uses Google's drive.file permission, which only covers files NutSplit creates. It cannot open your other files.

How is NutSplit different from Splitwise?

You add bills by talking to your AI instead of filling in forms, splits go item by item instead of dividing the total, every share is confirmed by the person who owes it, and the ledger is a Google Sheet you own. You can import your Splitwise group export to carry balances over.

Does it handle rent and utilities?

Yes. Set a fixed cost once. Fixed amounts are added every month automatically; for bills that change, like hydro, your AI asks for the amount.

Can a group use more than one currency?

Each group has one currency. For a trip abroad, make a separate trip group; people you've shared a group with before can be added without a new invite.

Stop doing roommate math.
