Local PII Sanitizer for AI

How to Safely Anonymize Sensitive Work Documents for AI

In the modern workplace, Artificial Intelligence tools like ChatGPT and Claude are incredible for summarizing meeting notes, drafting emails, and analyzing data. However, pasting confidential information—such as client names, financial figures, or unreleased news—into a public AI model poses a massive security risk. Our Free AI Prompt Anonymizer solves this problem by using Client-Side Browser AI to scrub your text before it ever leaves your computer.

Why In-Browser AI is the Safest Way to Redact PII

Most "text redactors" or "PII scrubbers" on the web require you to upload your text to their servers. This defeats the purpose of privacy. If you are trying to hide data from OpenAI, why would you give it to a random third-party server?

Our tool operates entirely differently. By utilizing Hugging Face's Transformers.js technology, this website downloads a tiny, highly-compressed Neural Network directly into your browser's local memory. When you click "Sanitize Text", the mathematical processing happens right on your laptop's CPU. We do not have a database. We do not have access to your text. The data never travels over the internet.

Who Should Use a PII Sanitizer?

• Human Resources (HR) Professionals: Summarize performance reviews or applicant resumes without leaking employee names or protected demographics.
• Lawyers & Paralegals: Format case notes and depositions while automatically swapping out client names with secure [PERSON] tags.
• Investigative Journalists: Draft articles based on confidential whistleblower leaks without exposing the organizations or locations involved.
• Healthcare Administrators: Keep patient notes compliant by stripping out identifiers before using AI for administrative structuring.

Frequently Asked Questions (FAQs)

Does this site save my prompts or text?
Absolutely not. Because the Named Entity Recognition (NER) model runs entirely within your local browser sandbox via WebAssembly, your text physically cannot be saved by us. If you disconnect from the internet after the page loads, the tool will still work perfectly.

Which entities are automatically redacted?
Our AI is trained to detect three primary categories of Personally Identifiable Information (PII): Names of people (swapped to [PERSON]), names of companies or institutions (swapped to [ORGANIZATION]), and geographic locations (swapped to [LOCATION]).

Is this tool completely free?
Yes. Because the compute power is handled by your device rather than expensive cloud servers, we can offer this enterprise-grade privacy tool completely free of charge.
