In May 2026, OpenAI started letting ChatGPT connect to people’s bank accounts. It is a fair thing to want. An AI that can see your spending can answer questions no budgeting app ever could, in plain language, at any hour.
It is also a fair thing to hesitate over. This post sets out what the feature does, what to ask before connecting any AI to your finances, and a different arrangement in which you decide exactly what the AI receives.
What ChatGPT’s finance feature does
As reported at launch, the feature started as a preview for Pro subscribers in the US. It connects to your bank through a bank-linking service, and once an account is connected, ChatGPT can read:
- balances
- transactions
- investments
- liabilities, such as cards and loans
The access is read-only, so ChatGPT cannot move money. If you disconnect, OpenAI says the synced data is deleted within 30 days.
None of that is careless. Read-only access and a clear way out are what you would hope for.
What connecting a bank account actually means
Linking an account is an all-or-nothing decision. The connection is how the feature works: it reads the account so it can build a picture of your money, and that picture is what makes its answers good.
So the question is not whether the feature is secure in the narrow sense. It is whether you want an AI service to hold your full transaction history: every payee, every amount, every date, for every account you link.
For some people the answer is yes, and the convenience is worth it. For others, a statement is the most personal document they own. It shows where they shop, who they pay, what they are treated for and who they support.
Four questions to ask before you connect anything
These apply to any AI tool and any finance feature, not just ChatGPT’s.
What exactly does it receive?
“Your transactions” can mean amounts only, or amounts with the merchant’s name, or the full line the bank printed. Find out which before connecting.
Can you give it less?
Most questions do not need everything. “Am I spending more than last year?” needs monthly totals. “Which subscriptions am I paying for?” needs payees, but only recent ones. A tool that offers one setting, everything, asks you to share more than most questions need.
How long does the access last?
A connection you made once for a single question may still be open months later. Look for whether access ends on its own or stays until you remember to revoke it.
Can you see what it took?
If an AI reads your finances, you should be able to see when it asked and what it was given, including the requests that were refused.
Another arrangement: you decide what the AI receives
LocoLedger is built around those four questions. One thing first, because it matters more than anything that follows: LocoLedger guards what your AI is sent, not what programs on your computer can open.
It works like this:
- Your statements live in one folder on your computer. When you add a document, LocoLedger copies it into this folder and leaves your original exactly where it is.
- Your AI connects to LocoLedger, not to your bank. You connect an AI app that speaks MCP, like Claude, and it asks LocoLedger for figures.
- The AI never receives your documents. It receives only the extracted details from the documents you allow. The files you added never leave this computer, at any setting — only figures read from them.
- You choose how much it can see. There are five levels, from Nothing to Transactions, real names, plus a row that adds your own categories. You can stop at monthly totals, or at transactions with the payees’ names replaced.
- You choose how long that lasts. Ask me each time, This session, 7 days, or Until I turn it off.
- Everything is written down. LocoLedger keeps a record of everything the AI has tried to access from it, even the rejected requests.
The five levels of what your AI can see has more on what each level sends, and how LocoLedger reads a bank statement covers how the figures are read without any AI.
What this does not protect
Replacing a name hides who you paid, not what or when. Dates and amounts are still personal, and the five levels explains what that means in practice.
So, should you?
If you are comfortable with an AI service holding your full transaction history, ChatGPT’s feature is a convenient way to get answers, and its read-only access and 30-day deletion are sensible.
If you would rather decide what the AI sees, question by question, and keep your statements on your own computer, that is the arrangement LocoLedger offers. It runs on Windows 10 and 11, and you can download it here.
