🎭 Mode
🔍 Detect
Letter and document protection
Detect English and Arabic names in greetings, recipient fields, signatures, common Arabic title forms, and likely full-name patterns without requiring Mr or Ms. Arabic has no capitalization, so likely-name matches always need review.
Use this list for lowercase names, unusual project names, or any sensitive phrase missed by detection. All matching occurrences are replaced.

🚨 Findings
Review sensitive text before sharing
Select pattern detectors, then choose placeholders, synthetic examples or masking. Run the tool and inspect every remaining line. Repeated detected values receive consistent replacements.
Example: two occurrences of the same email address use the same email placeholder. Names without titles, unusual phone formats and context-dependent identifiers may be missed.
Pattern matching cannot guarantee anonymization. A “no matches” result does not mean the text is safe. The downloaded mapping contains original sensitive values; keep it private and never include it with an AI prompt. Fake and masked modes are not guaranteed to be reversible.
PII Anonymizer: common questions
Can Claupt detect names without Mr or Ms?
Claupt checks greetings, signatures, labeled fields, and possible capitalized names without requiring a title. These are pattern-based detections, so review false positives and add missed names to the exact-phrase list.
Can I hide project names and contract numbers?
Yes. Enable Project names and Contract numbers, then review the matches. English and Arabic labeled fields are supported. Add unusual names or identifiers to the exact-phrase list to replace their repeated occurrences.
Does the PII Anonymizer redact the original PDF or Word file?
No. Claupt transforms pasted text. It does not remove metadata, comments, images, signatures, or hidden content from the original document. Review the complete output; automatic detection does not guarantee anonymity.
