Import sensitive material
Drop in PDFs, Word files, screenshots, scans or pasted text without sending the originals to a web service.
Local offline redaction software
LocalMask
Prepare sensitive documents before AI analysis, external sharing and review.
Redact and anonymize PDFs, Word files, images, scans and text on your computer. Keep useful context with aliases, review every hit, then export a clean copy.
Core processing runs locally
Review before export
Export redacted copies
AI needs context, not raw identifiers
Redact the document, keep the structure.
Review detected entities
Inspect names, organizations, accounts, addresses and visual targets before exporting a redacted copy.
Keep context for AI
Use stable aliases such as Person A and Company A so AI can reason without seeing direct identifiers.
Why not just use a PDF editor or PII framework?
Built for document work, not just detection.
LocalMask is designed for people who need a usable redaction workspace: import, detect, review, alias, export and restore AI output from the local mapping.
Desktop workflow instead of a developer-only PII API
PDF, Word, scan and image handling instead of prompt text only
Local review and export before AI analysis or external sharing
Alias mapping stored locally for restoring AI-generated output
