Claude Personal Finance: what it does, and how to give it a ledger that remembers

What Claude Personal Finance does

Claude Personal Finance lives in a Personal Finance hub inside Claude. You link bank and credit card accounts through Plaid, and Claude can see the account names and types, the last four digits of each account number, balances, credit limits and up to two years of transactions. The access is read-only: Personal Finance cannot move, manage or invest your money.

Once linked, you ask in plain words. Claude sorts spending into categories such as rent and utilities, food and drink, and shopping; flags duplicate charges, unexpected fees and bills that keep rising; tells you whether you are spending more than you earn; and explains what a card’s APR has cost you in interest over the past year.

Anthropic says the feature carries no ads or sponsored recommendations, offers no cards, loans or savings accounts of its own, and does not use Personal Finance chats to train its models. It is not designed to give investment advice, and at launch it is a beta for subscribers in the United States.

How ChatGPT’s finance feature compares

OpenAI got there first. On 15 May 2026 it previewed a finance experience for ChatGPT Pro users in the United States, also built on Plaid and reaching more than 12,000 institutions. You open it from a Finances item in the sidebar or by asking in a chat, and it shows a dashboard of portfolio performance, spending, subscriptions and upcoming payments, on the web and on iOS.

ChatGPT cannot see full account numbers or change anything in a connected account. If you disconnect, the synced data is removed from ChatGPT within 30 days, and you can view and delete the financial memories it keeps. OpenAI said Plus users would follow and that support for Intuit was planned, for questions such as the tax effect of selling shares.

Both, then, are the same idea from two companies: link your accounts to the assistant you already use and talk about your money. If that is all you need, either does it well. Compare 2Fin with ChatGPT Finances for the side-by-side.

A conversation and a ledger do different jobs

A conversation is built to answer the question you just asked. It reads what the bank sends, works out a picture, and gives it back — and the next question starts from the bank data again. That is exactly right for “what did I spend on takeaway?” and less suited to the jobs that build up over a year.

A ledger is built to keep things. In 2Fin every transaction is categorised as it arrives and keeps the reason for its category — your rule, a learned pattern or Fin — so you can see why a figure is what it is. Fix a category once and a rule files every matching transaction after it. Tag a cost business, work-related or personal and it counts toward your deductions and GST or VAT from that moment on.

By tax time the difference is the whole year. The deductions are already totalled, the activity statement is prepared if you file in Australia, the United Kingdom, Canada, New Zealand or Singapore, and the exports are labelled for your tax authority — the IRS, HMRC, the CRA, the ATO and more — ready for you or your accountant.

Numbers you can trace back to a source

When money meets tax, you want the same answer every time you ask. 2Fin works out GST, VAT, income-tax brackets and levies in code from one rate ledger, with each rate dated to the period it applies to, so the same inputs always give the same figure — whether you read it in the app, in a spreadsheet, or in Claude.

The rates themselves are public. The free 2Fin Tax MCP gives any assistant standard GST and VAT rates for 193 countries, income tax for 57, company tax for 139 and capital gains for 71, each figure cited to its own source and date, with no login.

Inside your own account, the live estimate combines salary, sole-trader profit and net rental income, less tax withheld, in Australia, the United Kingdom, Canada and India, and in the United States for one kind of income at a time. It is general information to plan with, not personal tax advice — check what applies to you with your accountant or the relevant tax authority.

Connect Claude or ChatGPT to your 2Fin ledger

Start a free 2Fin account and bring your transactions in: a read-only feed you connect with your own key, a statement upload in CSV, Excel, PDF, OFX, QIF, CAMT.053 or MT940, or a spreadsheet feed. Fin categorises them as they arrive.

Then add 2Fin to your assistant. Connect Claude, ChatGPT or Cursor through 2Fin’s MCP server, and approve the access on the consent screen: an assistant reads your records, and changes them only with a write permission named there.

Now ask the way you would in Claude Personal Finance — what you spent, what looks deductible, which bills are due and who still owes you — and the answer comes from your categorised books. Switch assistant tomorrow and the books do not move.

See the ledger as a spreadsheet

Some answers are easier to see than to read. 2Fin sends finished transactions to Excel, Google Sheets, Notion or Airtable as rows, and the web app draws them as interactive views — a month as daily towers, categories across the months as a landscape, money in and out as flows — each clicking through to the transactions behind it.

The sheet below is a sample. Change a category and the rule re-files the matching rows, total by category, tax tag or where each category came from, ask the same question from Claude, ChatGPT or Cursor, and download what you see as a CSV.

Keep the ledger on your own machine

Some money is private enough that you would rather it never left your computer. The 2Fin desktop app for Windows keeps your database and receipts in a folder you own and works offline, lets you bring your own model key or run a local model, and shows a record of every outbound request.

The same records still work with an assistant when you want one: connect it to 2Fin and approve what it can read, or keep everything on the desktop and use Fin there.

If you live outside the United States

Claude Personal Finance and ChatGPT’s finance preview both opened in the United States first. 2Fin works in every country, with GST, VAT or sales tax on record for each, income-tax estimates in five, activity statements prepared for Australia, the United Kingdom, Canada, New Zealand and Singapore, and depreciation on the authority’s own rules in eight countries.

And the assistant side is not tied to a country at all. Wherever you use Claude or ChatGPT, it can read your 2Fin records through MCP — so the conversation you saw announced for US subscribers is one you can have about your own books today.
