PII masking Chrome extension for work AI chat
Mask sensitive details from work emails, PDFs, tickets, and internal notes before pasting them into ChatGPT, Claude, Gemini, or other AI assistants.
What it handles
Mask before sending
Clean names, emails, phone numbers, IDs, account references, and other sensitive details before a prompt reaches an external AI assistant.
Built for work email
Use it when copying customer emails, support threads, HR notes, vendor messages, or internal updates into an AI chat.
Safer PDF copy-paste
Mask sensitive snippets copied from invoices, contracts, statements, onboarding files, and other office PDFs.
Local browser workflow
The extension is designed to mask text locally in your browser, so the first privacy step happens before the AI chat window receives the text.
Built for AI chat pages
Privacy Mask works on the AI tools teams already use: ChatGPT, Claude, Gemini, Grok, Copilot, DeepSeek, and Perplexity.
Company-friendly guardrail
Give employees a simple habit for removing customer, employee, vendor, and account details from ad hoc AI prompts.
What Privacy Mask does at work
A small browser workflow for office copy-paste moments: emails, PDFs, tickets, notes, and document excerpts that should not reach an AI chat with raw sensitive data inside.
Sensitive text masking
Replace names, emails, phone numbers, IDs, and other sensitive strings with safer placeholders.
Returns: A masked version of the prompt that is easier to share with an AI assistant.
Email and ticket cleanup
Mask names, emails, phone numbers, addresses, ticket IDs, and customer references before asking AI to summarize or rewrite a work thread.
Returns: A cleaned support, sales, HR, or operations prompt with personal details replaced.
PDF and document snippets
Clean pasted text from invoices, contracts, bank statements, onboarding PDFs, and vendor documents before using it in AI chat.
Returns: A safer document excerpt for analysis, rewriting, explanation, or translation.
Local browser processing
Keep the first privacy step inside Chrome before text is sent to an external chat surface.
Returns: A browser-side masking workflow for day-to-day AI use.
AI chat coverage
Use the extension on common AI assistants, including ChatGPT, Claude, Gemini, Grok, Copilot, DeepSeek, and Perplexity.
Returns: A consistent masking habit across the AI chat tools your team already opens.
Review before paste
Check the masked output before using it in a prompt so the human still owns the final share decision.
Returns: A cleaner prompt that can be reviewed before it leaves the browser.
Start in Chrome. Scale through Document Anonymization.
Privacy Mask is the quick browser step for an employee who is already copying a work email, PDF excerpt, support ticket, contract clause, or internal note into an AI chat. Paperwork Document Anonymization is the larger service for teams that need controlled document workflows, API routing, audit trails, and deterministic token handling across the company.
Explore Document AnonymizationChrome extension for ad hoc prompts
Use it at the moment of copy-paste, before raw customer, employee, vendor, or account details reach ChatGPT, Claude, Gemini, or another AI assistant.
Office content first
Built around the everyday risk: emails, PDF snippets, tickets, internal updates, invoices, contracts, HR notes, and vendor messages.
Service for document pipelines
Use Document Anonymization when the workflow needs API access, batches, gateway controls, model routing, and company-wide handling rules.
Enterprise controls when needed
Move from a personal browser guardrail to audit logs, deterministic placeholders, re-identification workflows, and managed team deployment.
Made for work emails, PDFs, and document snippets
The risky moment is usually not a formal upload. It is someone at work copying a customer email, a PDF invoice, a contract clause, an HR note, or a support ticket into ChatGPT to summarize, rewrite, translate, or explain it.
Privacy Mask is built for that everyday office habit: mask the sensitive parts first, review the cleaned text, then paste the safer version into the AI assistant.
Best for office teams that use AI chat on real work text but should not expose raw customer, employee, vendor, or account data.
Clean the prompt before it enters AI chat
Most accidental data leaks happen in ordinary prompts: a customer email, a phone number, an employee name, an account reference, a copied support thread. Privacy Mask adds a small cleanup step before that text is pasted into an AI assistant.
The point is not to slow the team down. It is to make the safe path the default path: mask first, review the output, then send the cleaned version.
The user still reviews the result before sharing it with an AI assistant.
A privacy habit that lives where prompting happens
Teams do not always start from a formal document workflow. Sometimes they are in Chrome, drafting a support answer, summarizing a ticket, rewriting an email, or asking a model to explain a vendor message.
Privacy Mask is built for that surface: supported AI chat pages in Chrome, with masking handled locally in the browser before the prompt is shared.
Also targets Grok, Copilot, and DeepSeek chat pages.
