How AI Document Guard works

01
Upload
User uploads file(s) via drag-and-drop or file picker. Documents up to 200 MB supported.
02
Analyse & Confirm
The system highlights detected entities — Names, Organisations, Emails, Phones, Sums, Passports, Bank accounts, Tax IDs. The user reviews highlights and confirms each redaction.
03
Download cleaned archive
Produces sanitized_results.zip with cleaned file in original format, Markdown version, .docx version, and report.json with full audit trail.
No blind deletion. Every redaction is confirmed by a human.

Built for real document workflows

Audit-ready reports
Every run produces report.json — a full audit trail of every change made to the document.
