Find and filter synced transactions by date, amount, merchant, or category before importing.
Version Control
Every import is committed to Git, giving you a full audit trail and the ability to roll back any changes.

Frequently asked questions
Which banks are supported?
Bank Sync connects through Plaid to banks, credit unions and brokerages in the United States and Canada, including Chase, Bank of America, Wells Fargo, Citi and Capital One. UK and European banks are not supported yet; import their statements with Smart Import instead. You can check whether your bank is supported during the connection flow.
Is my banking data secure?
Your bank credentials are never stored on or sent through our servers. You sign in to your bank inside Plaid's encrypted flow, and Beancount.io receives read-only transaction data.
How accurate is the AI categorization?
Accuracy depends on how clear the merchant names are and how well your chart of accounts covers your spending, so review every suggestion. Categorization runs only when you ask for it: Beancount.io then sends each pending transaction's date, payee, description and amount, plus your account names, to our AI provider (Anthropic, with OpenAI as a fallback). When you link a bank, its account names, types and last four digits are also sent so the AI can suggest an account mapping.
How often are transactions synced?
You can manually sync at any time with one click. A background job also syncs every connected bank about every six hours, so new transactions are waiting for review without any manual effort. New transactions typically appear within seconds of syncing.
Can I import historical transactions?
Yes. When you first connect a bank account, Plaid fetches recent history, typically up to 90 days depending on your bank. For older transactions, import your bank's CSV or PDF statements with Smart Import.
What if AI categorizes something wrong?
You always have full editorial control. Every transaction goes through your review before being committed to your ledger, and you can change any AI suggestion before you import it.
