Trezzit

A bank statement shows what you paid, not what you spent. If you pay $100 at Walmart and $70 is for roommates, you spent $30. If a friend covers your dinner, that is still your expense, even though it never appears on your bank statement.

Trezzit keeps personal and shared expenses in one place, down to each item and your share of it. With the Trezzit connector, Claude can read and update those expenses in plain language:

• Track what you actually spend: search by item, store or category, and ask what you spent last month. Totals count only your share, across personal purchases and shared bills.
• Scan and itemize receipts: turn a receipt photo, screenshot or PDF into verified line items, tax and tip, then save it as personal or split it with a group (needs AI features turned on in Trezzit).
• Split bills: equally, by percentage, by exact amounts, or item by item with roommates, partners or trip groups, including one-off guests. See who owes whom and record settle-ups.
• Recurring expenses: rent, utilities and subscriptions, with their splits set once. See what's due this month, then settle, skip or change a period.
• Check against your bank statement: list what you paid and settled, so Claude can match it line by line. Trezzit never asks for your bank login.

Trezzit never moves money. It has no access to bank accounts or cards; recording a settlement only notes a payment made elsewhere.

Built for accuracy and control: pennies are split exactly, a new bill can be previewed before it's saved, and every action Claude takes appears in Profile → Connected AI apps, where you can also disconnect it.
