BillAutopsy: Local Tool Audits Bank Statements to Expose Hidden Subscription Leaks

A developer built BillAutopsy, a fully local tool that audits monthly bank and credit card statements without uploading them to any cloud service. The author notes that bank PDFs often break into messy rows when copied into spreadsheets, and that cryptic merchant codes hide price hikes, duplicate gym charges, and free trials that quietly turn paid. The app extracts transactions with pdfplumber and checks that balances reconcile exactly before any AI is involved. It then normalizes merchant names locally and uses a classifier, TabPFN with a statistical fallback, to flag price creep, trial conversions, and duplicate charges. According to the submission, the demo caught about $748.88 in annual waste across three statements.
