About this extension
Paste or upload as usual. Names, identifiers, and other private details are masked before they reach AI websites.

Review what changed, then send. AI websites are covered by default. Choose Every website in the toolbar popup for broader coverage. On supported conversations, PHI Mask can restore original values locally in replies.

HOW IT WORKS

PHI Mask has detectors for PHI and PII based on patterns such as: name, date of birth, address, phone number, email address, health card number, record number, and social insurance number of the person you are writing about. Based on your settings, these can be masked before any AI can see it; and then unmasked for your eyes only.

WHAT WE RECEIVE

Nothing. The text and files you mask stay in your browser. We do not receive them.

PHI Mask is HIPAA-compatible, not HIPAA compliant. Your file is masked in your browser and never sent to us, so there is no BAA to sign.

FILES

Attach a file the way you normally would. PHI Mask changes the details inside it first, then attaches the masked copy. Use the file's PHI Mask control to compare the original and masked versions.

PRICE

Free for personal use, licensed for client work. No account needed.

WITHOUT INSTALLING

For one-off masking, the online masker at phimask.com/mask-data handles text, screenshots, and files.

FEATURES

• Paste text as usual.

• Upload files without preparing them first.

• See every change before you send.

• Read replies with the original details back in place.

COMMON QUESTIONS

Does PHI Mask store or log my data and files?

No. Detection and masking run locally in your browser, and your original input, filename, detected values, and stand-in map stay on your machine.

Is PHI Mask an AI service?

No. PHI Mask uses pattern recognition to identify names, emails, addresses, etc.. which means detection easily runs on your device, in your browser, and works offline. Your text and files are not uploaded.

Is PHI Mask HIPAA compliant?

PHI Mask is HIPAA-compatible, not HIPAA compliant. Your file is masked in your browser and never sent to us, so there is no BAA to sign.
Developer comments
PHI Mask is not an AI service. It does not use generative AI or an LLM. Detection and masking happen locally in your browser before you submit text or files to an AI website.

PHI Mask does not receive the text or files you mask.
