In practice
What you can ask ChatGPT.
Questions that reach past one account, one statement period, or the merchant names your bank sends.

Why Synci
How do you connect ChatGPT to your bank account?
ChatGPT has no way to log in to your bank, and a pasted statement is stale the moment you send it. Synci is the connector in between: you link your bank through its own regulated open-banking login, then install Synci from ChatGPT's directory.
From then on ChatGPT reads the accounts you picked whenever you ask, so it works from your current numbers. Find your bank in the browser lower down.
Features
ChatGPT
- One-click install from ChatGPT's own directory, no setup token or server URL
- Ask about balances, spending, holdings and net worth in an ordinary conversation
- Answers come from your latest synced data, refreshed on your plan's schedule
- Read-only by design: ChatGPT cannot move money or change anything
- You choose which accounts it may read, and can disconnect at any time
Scope
Exactly what ChatGPT can and cannot do.
ChatGPT reaches your accounts through five read-only tools.
- list_accounts
- get_account_balance
- list_transactions
- list_holdings
- list_connections
ChatGPT can
- List the accounts you shared, across banks, brokerages and crypto exchanges
- Read recent balance snapshots, with the timestamp they were taken
- Read transactions in a date range you or it asks for
- Read investment and crypto holdings: symbol, quantity, market value
- Check the health of your connections, so it can tell you when data is stale
ChatGPT cannot
- Move money, make payments, or place trades
- Change anything at all: the server is read-only and has no write operations
- See accounts you did not share, or reach your bank directly
- See your bank login, which never leaves your bank's own flow
- See sensitive identifiers: IBAN, BBAN, card numbers, phone numbers and owner names are omitted
Enrichment is opt-in and separate from this: when you turn it on, only pseudonymised transaction data reaches our enrichment provider, and it is never used to train models or shared with unrelated third parties. See our privacy policy for the detail.

FAQ
Common questions
Connect your bank to Synci through its own open-banking login, choose which accounts to share, then search for Synci in ChatGPT's directory and click Install. Sign in and ChatGPT can read those accounts. Because Synci is already listed, there is no developer mode to switch on.
Only the accounts you explicitly share, and only to read them. It can list them and read balances, transactions and holdings. It cannot move money, place trades or change anything, and it never sees your bank login, IBAN or card numbers.
ChatGPT reads your latest synced data at the moment you ask. Synci refreshes from your bank every hour to every 6 hours, depending on your plan and your bank's own limits. Balances can lag transactions, so ask for the timestamp when it matters.
On Basic, 60 days. On Pro, up to 2 years, where your bank provides it: some PSD2 banks hand over about 90 days, others up to 24 months. Enough for a year-over-year comparison.
No. A pasted CSV or PDF is frozen at export time, and you redo the work every month. With Synci connected, ChatGPT reads the current data itself.
Remove Synci in ChatGPT, or revoke its access from your Synci account, which cuts it off immediately. Unsharing individual accounts narrows what it sees.
Every institution Synci supports across Europe and New Zealand, plus supported brokers and exchanges. Search for yours above to check.
