        "longDescription": "A bank statement shows what you paid, not what you spent. If you pay $100 at the grocery store and $70 of it is for your roommates, you spent $30. If a friend covers your dinner, that is still your expense, even though it never shows up on your bank statement.\n\nTrezzit is an itemized expense ledger. It keeps personal and shared expenses in one place, down to each receipt item and your share of it. Connect Trezzit to read and update those expenses in plain language:\n\n\u2022 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.\n\u2022 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.\n\u2022 Recurring expenses: rent, utilities and subscriptions, with their splits set once. See what's due this month, then add, skip or change a period.\n\u2022 Check against your bank statement: list what you paid and settled, so it can be matched line by line. Trezzit never asks for your bank login.\n\nWho it's for: anyone who wants to know what they really spend, including people who share costs with roommates, partners, friends or travel groups. You need a Trezzit account, and you sign in to it when you connect.\n\nGood to know:\n\u2022 Trezzit never moves money. It has no access to bank accounts or cards; recording a settlement only notes a payment made elsewhere.\n\u2022 It doesn't connect to banks or import card transactions. Expenses come from what you and your groups add, and from receipts.\n\u2022 Adding a group bill or a settle-up notifies the other members, just as it does in the app.\n\u2022 Only a bill added through this connection in the last 30 minutes can be deleted here; change older bills in the Trezzit app.\n\u2022 A split link creates a public page that anyone with the link can open.\n\nBuilt for accuracy and control: pennies are split exactly, a new bill can be previewed before it's saved, and every action taken through this connection appears in Profile \u2192 Connected AI apps, where you can also disconnect it.",
