How to Use AI on Real Format Data — Without Sending a Single Real Name

Our tool is a Security Shield for AI inputs, working via the copy-paste web workspace or the Chrome Extension. It blocks personal details like names or emails by swapping them with secure tags (e.g., [NAME_1]) offline. This aligns with enterprise bulk processing, keeping your chats private. The Chrome Extension places a protective button inside ChatGPT, Claude, and Gemini to automate the process. By executing Named Entity Recognition entirely in local memory, PrivacyScrubber preserves the usefulness of ChatGPT Advanced Data Analysis, Claude Projects, and programmatic ML pipelines for "bulk anonymize text files" workflows without introducing external risk. This zero-trust architecture is also highly relevant for teams navigating enterprise bulk processing.

You don't have to take our word for it. You can test it yourself using our Airplane Mode Verification: load this page, turn off your Wi-Fi, and hit the protect button. It works perfectly without the internet, which is the gold standard for verifiable data sanitization and personal safety. If it works offline, you know your data is staying with you. See how this methodology translates to other sectors in our guide on verifiable data sanitization.

Zero-Trust Configuration & Threat Model

Deploying local data controls for bulk anonymize text files is critical when routing inputs to external platforms like ChatGPT Advanced Data Analysis, Claude Projects, and programmatic ML pipelines. To safeguard user context, PrivacyScrubber isolates individual records by tokenizing key data points before cloud transmission. For this specific workflow, the browser-based Named Entity Recognition (NER) classifier targets identifying markers, achieving an average processing speed of 7ms. This allows team members to run complex queries involving redact log files while satisfying strict internal data security requirements.

Verification Protocol

  • Scan prompt text for explicit identifiers related to bulk anonymize text files.
  • Execute client-side regex rules to sanitize variables associated with redact log files.
  • Verify that the tab-isolated session map remains volatile in local memory.
  • Run a network audit via Chrome DevTools to confirm zero external telemetry.

FAQ: What Happens in the Browser, Stays in the Browser

Does protecting data before AI processing satisfy GDPR requirements for processing datasets?
Yes. Processing pseudonymized data for a secondary purpose (AI analysis or drafting) aligns with GDPR requirements for processing datasets because no personally identifiable data is transmitted to the AI provider. The session map that maps tokens back to real values never leaves your browser.
What specific PII does PrivacyScrubber detect for format use cases?
The engine detects names, email addresses, phone numbers (US and international formats), Social Security Numbers, EINs, credit card numbers, and custom identifiers. PRO users can add custom regex rules to match format-specific patterns such as bulk anonymize text files.
Can I reverse the redaction if I use PrivacyScrubber to mask format data?
Yes. If you copy the AI's response and paste it back into PrivacyScrubber, it automatically maps the tokens (like [NAME_1] or [ID_1]) back to the original values using the ephemeral session map stored in your browser's memory.
Can PrivacyScrubber be used offline for bulk anonymize text?
Yes. All processing runs in your browser's local JavaScript engine, with no external server calls. Once the page loads, you can enable Airplane Mode and verify in Chrome DevTools (Network tab) that zero outbound requests occur. All cryptographic operations (including client-side pseudonymization and reverse-revealing) utilize hardware-accelerated XChaCha20-Poly1305 encryption and Argon2id key derivation running entirely inside browser RAM, ensuring your format data stays 100% on your device.
How can I verify that PrivacyScrubber sends zero data to servers?
Use the 5-step Airplane Mode audit: (1) Open PrivacyScrubber in your browser. (2) Disconnect your network connection (enable Airplane Mode). (3) Paste a text sample containing names, emails, and phone numbers. (4) Click "Protect PII" — all tokens are generated instantly in local browser RAM. (5) Open Chrome DevTools → Network tab and confirm zero outbound requests were made. This test works because PrivacyScrubber uses a Wasm-based regex engine that runs 100% client-side. The session token map (e.g. [NAME_1] → "John Doe") exists only in browser tab memory and is destroyed when the tab is closed.
Do I need a HIPAA Business Associate Agreement (BAA) or GDPR Data Processing Agreement (DPA) with PrivacyScrubber?
No. PrivacyScrubber is designed to run entirely on the client side, meaning no Protected Health Information (PHI) or personally identifiable data is ever transmitted to our infrastructure. Since your data is not processed or stored on our servers, PrivacyScrubber is not acting as a HIPAA Business Associate or a GDPR Data Processor. Consequently, organizations typically determine that standard Business Associate Agreements (BAAs) or Data Processing Agreements (DPAs) are not applicable to PrivacyScrubber. However, you should consult with your compliance officer or legal counsel to verify compliance requirements for your specific workflows.
Can I customize detection rules specifically for bulk anonymize text files PII safety?
Yes. In the PRO edition of PrivacyScrubber, you can configure custom regular expression (regex) rules designed to target unique patterns associated with bulk anonymize text files and other sector-specific nomenclature. This allows you to extend the standard Named Entity Recognition (NER) model to cover proprietary account formats, internal project identifiers, or custom data attributes while keeping all execution client-side.
Is pasting sensitive data into ChatGPT safe?
Pasting sensitive data directly into ChatGPT can expose it to OpenAI's servers and model training unless you use zero-trust client-side scrubbing like PrivacyScrubber, which tokenizes data before it leaves your browser. Protect your workflows for $15/mo with PRO.
How does client-side PII redaction work?
Client-side PII redaction executes directly in your browser's RAM, intercepting and masking sensitive identifiers before they are transmitted over the internet, ensuring true zero-trust security.
How does the Secure Workspace differ from the Browser Extension?
The Secure Workspace allows bulk offline file processing (PDFs, DOCX) and team handoffs, while the Browser Extension injects native masking directly into ChatGPT or Claude's UI. Both are included in our zero-trust ecosystem.
What is the PII MCP Server used for?
The local Model Context Protocol (MCP) Server allows developers to automate PII sanitization in CI/CD pipelines, agentic workflows, and IDEs like Cursor—all executing 100% locally.
