Automatic bank sync via Plaid, read-only

Quaestor Ledger connects to your accounts through Plaid with a read-only bank link — it can read transactions and balances across 12,000+ institutions, but it can never move your money.
Card required, but you won't be charged today. Cancel anytime.
In short: You connect accounts through Plaid Link. Quaestor receives a read-only connection that cannot initiate payments or transfers. It covers checking, savings, credit cards, loans, and investments across 12,000+ institutions, scales to 50+ accounts (200 cap), and also supports CSV/QIF import.

How it works

You link an institution through Plaid, using Plaid Link — the hosted connection flow. You authenticate with your bank directly, and Quaestor receives a connection scoped to data only.

The connection requests read-only account, transaction, and liability information. Quaestor can read your transaction history and balances, but it has no ability to move money, initiate payments, or start transfers.

Plaid documents secure connections to more than 12,000 financial institutions globally, so most banks and card issuers are covered. Synced accounts span checking, savings, credit cards, loans, and investment accounts, all in one ledger.

Scale

Quaestor Ledger is built for complex, multi-institution finances. It comfortably handles 50+ connected accounts, with an upper cap of 200 accounts.

That headroom is meant for people running several banks, multiple credit cards, joint and personal accounts, brokerages, and loans side by side — without forcing you to pick which accounts to leave out.

Other ways to add data

Not every account needs a live connection. You can import history directly with CSV or QIF files.

This is useful for institutions outside Plaid coverage, older archived statements you want in your ledger, or accounts you simply prefer to maintain manually.

Frequently asked questions

How does Quaestor Ledger connect to my bank?
You connect through Plaid Link, the secure hosted flow Plaid provides. You authenticate directly with your institution; Quaestor receives a read-only connection that returns account data. Plaid supports 12,000+ institutions, including checking, savings, credit cards, loans, and investment accounts.
What does "read-only" mean — can Quaestor move my money?
No. The connection requests only the transactions and liabilities products, which return account data. It cannot initiate payments, transfers, or any money movement. Read-only means Quaestor can read your balances and transaction history but cannot act on your accounts.
How many accounts can I connect?
Quaestor Ledger is designed for complex, multi-institution finances and comfortably handles 50+ connected accounts, with an upper cap of 200 accounts.
What if my bank is not supported or I want to add data manually?
You can import history with CSV or QIF files. This covers institutions outside Plaid coverage, older archived data, or accounts you prefer to manage manually.
Does Quaestor train AI on my bank data?
No. Quaestor does not use your bank data to train AI or intelligence systems. AI is used elsewhere in the product for receipt parsing and chat, with training-use restrictions configured where available. See the Privacy Policy for details.
