Anonymize a bank statement before analyzing it with AI

Turn a statement into Markdown with account holder, ID, account and card numbers hidden, leaving the transactions for the AI to analyze.

About this tool

Asking an AI to categorize your spending or summarize a statement is genuinely useful. Handing it your account number, your card and your ID is not.

We detect and replace card-formatted numbers, ID documents, names labelled as account holder, addresses and contacts. Each transaction's dates and amounts are kept: without them the AI could not do the analysis you are asking for.

Even so, review the result. Account-number formats vary a lot between banks and one may slip through.

How it works

  1. 01

    Drop the bank statement PDF.

  2. 02

    Review each highlighted item: you can switch anonymization off to compare.

  3. 03

    Copy the Markdown or download it as .md and use it with your AI assistant.

Questions

Does it detect account numbers?
Card-shaped ones (groups of four digits) yes. Bank-specific formats may slip through: review and edit before sharing.
Are balances and transactions kept?
Yes. They are exactly what the AI needs to categorize or summarize, and on their own they do not identify a person.
