Drop a document to detect and strip personal data — it never leaves your browser
Document Anonymiser — Finance
Strip personal data (names, emails, phone numbers, SSNs, card and account numbers) from a document — as text, image pixels, and metadata — entirely in your browser. Powered by IOGate. Nothing is uploaded. Free for a limited time.
How it works
- Drop a statement, report, or ledger — detection (Powered by IOGate) runs entirely in your browser, so no financial data is uploaded.
- Review the summary: client names, emails, phone numbers, account and card numbers are listed by type with confidence scores so you can confirm nothing slipped through.
- Download the anonymised file with PII replaced by consistent placeholders like [ACCOUNT_1] — plus an optional local mapping key to reverse it.

No AI means no hallucinations
Compare Files uses a deterministic, logic-based engine — not a language model. It reports every change that is actually in your files, and never invents one.
