Local PII Sanitizer for AI
Mask sensitive names, emails, phones, locations, and credentials directly in your browser before pasting text into ChatGPT or Claude. 100% private. Zero server uploads.
Why Client-Side PII Sanitization Matters for AI
Generative AI platforms like ChatGPT, Claude, and Gemini process billions of tokens every day. When employees and researchers paste unredacted documents, transcripts, and financial ledgers into public AI tools, they risk exposing Personally Identifiable Information (PII) to remote servers, third-party loggers, and model training datasets.
How PII Sanitizer Protects Your Workflows
- Zero Network Transmission: Sanitization algorithms execute inside your local browser memory via JavaScript and WebAssembly. No raw text is ever sent over the network.
- Maintains Semantic Context: Rather than blacking out phrases, identifiers are mapped to standardized tokens (e.g.,
[PERSON_1],[EMAIL_1],[LOCATION_1]). This allows AI assistants to understand roles and grammar without knowing real identities. - Reversible Workflows: Once the AI generates its analysis or response, you can easily map the placeholder tokens back to original names in your local editor.
