Anonymized
Generic tokens: [PERSON], [LOCATION]…
When you don't need to keep links between occurrences.
How it works
How Safe-Doc pseudonymizes or anonymizes documents.
Safe-Doc secures external AI usage with a simple process: pseudonymize (or anonymize), analyze, de-anonymize.
Interactive demo
Paste a document excerpt: Safe-Doc detects and replaces personal data before AI. No storage, no real data sent to a model.
Open the live demo on a contract, email, or HR note.
Open the interactive demo1) Import: File, Paste, or Data Room
Import options
- Upload a file: drag & drop or select a document (PDF/DOCX/TXT).
- Paste text: great for an email, an excerpt, a note.
- Data Room (multi-docs): import multiple documents at once for multi-document analysis.

Data Room
Why Data Room helps
With pseudonymization, the same entity remains the same pseudonym across documents.

Great for diligence, contracts, multi-piece case files.
2) Choose a mode: Anonymize, Pseudonymize, or Fake data
Pseudonymized
Numbered, consistent tokens: [PERSON_1], [ORG_2].
Best to preserve narrative consistency across a document set.
Fake data
Readable replacements (invented names/addresses) for a "natural" text.
Useful for review and presentation while masking real values.
3) Increase protection: N1-N2, N3 (roadmap)
Principle
Higher levels reduce re-identification through context (dates, amounts, locations, writing style).
N1-N2
Standard · Advanced
Direct identifiers (PII) and risky context: tokenization, cleanup and generalization (dates, amounts, locations, references).
N3
High security
Stylistic fingerprint and weak signals. Roadmap Q3 2026.
Visual example
"-17.3M - Feb 12, 2026 - Rouen"
↓
N1-N2: contextual reduction · N3 (roadmap)
↓
"mid-teen millions - Q1 2026 - North France"
Goal: keep useful meaning while reducing identifiability.
4) Review: detected entities and residual scan
What you control
- Detected entities: people, orgs, locations, emails, phones, IBAN, amounts…
- User choice: uncheck what you don't want to mask.
- Comparisons: views by source (e.g., model vs regex) depending on UI.
Why human review matters
Automated detection can produce false positives and false negatives. Indicators (residual scan / leakage score) help assess risk, but don't replace a final review.
