How does an AI bank statement converter work?

Unlike template tools that look for one bank's fixed layout, StatementFlow uses Claude vision to read whatever is on the page — so it handles scans, photos, and unfamiliar or foreign layouts.

The model returns transactions in a strict structured format (date, description, amount, balance), which is then checked deterministically: each row must move the running balance by exactly its amount, or it gets flagged.

That combination — flexible reading plus a rigid math check — is why it's both broad and accurate.
