How it works

Keep the workflow simple.

Protect the private details locally, review them, use AI on the protected version, then restore the final answer on your device.

Protect locally

Paste the customer message. Layrin replaces private details with safe tokens before anything leaves your device.

Original message

Hi, Sarah Kim says order ORD-88421 arrived damaged, and the replacement linked to tracking number 1Z999AA10123456784 has not moved since Monday. She is asking whether we can either refund invoice INV-2033-7719 or ship a new replacement today. She can be reached at sarah.kim@example.com if we need photos.

Review protected text

Check the tokenized version and decide exactly what may be shared with AI.

Protected version

Hi, [PERSON_1] says order [CONFIDENTIAL_NUMBER_1] arrived damaged, and the replacement linked to tracking number [CONFIDENTIAL_NUMBER_2] has not moved since [DATE_1]. She is asking whether we can either refund invoice [CONFIDENTIAL_NUMBER_3] or ship a new replacement today. She can be reached at [EMAIL_1] if we need photos.

Add your instruction

With Protect, add your instruction in the AI tool you choose. With Pro, write it in Layrin and review the protected instruction before it is sent.

Example instruction

Draft a calm professional reply apologizing for the issue, saying we will check the shipment today, and asking for photos before deciding on a refund or replacement.

AI response with tokens

The AI writes a useful response using protected tokens instead of the original private details.

Protected AI response

Hi [PERSON_1], I’m sorry to hear that your order arrived damaged and that the replacement shipment has not updated since [DATE_1]. We’ll check the status of tracking number [CONFIDENTIAL_NUMBER_2] today. Could you please send us a few photos of the damaged item? Once we review them, we can confirm the best next step, either a replacement or a refund for invoice [CONFIDENTIAL_NUMBER_3]. Thank you for your patience. Alex

Restore locally

Layrin restores the final response locally before you send it.

Designed around one boundary

Your real data stays local.

You approve the protected version

Original values stay in your local vault

Final answers are restored locally

Positioning

Not another chatbot. A local privacy layer before AI.

Use it for client correspondence, internal notes, support replies, HR messages, and business drafts when the writing can go to AI but the raw details should not.

FAQ

A few quick answers

How can I protect sensitive data before using ChatGPT or another AI?

Protect the text locally in Layrin, review the placeholders, use AI on the protected version with Protect or Pro, then restore the response on your device.

Is Layrin an anonymization or PII-redaction tool?

People often search those terms. Layrin uses reversible local tokenization: sensitive values are replaced with placeholders and can be restored on your device. It is not irreversible anonymization.

Can Layrin restore protected values in the AI response?

Yes. After the AI replies with placeholders, Layrin restores the original values locally on your device.

Does Layrin upload PDF or Word files?

No. Layrin currently works with pasted text. You can paste text from emails, reports, contracts, notes, and other professional sources.

Does the AI see my original sensitive values?

No. Layrin protects approved sensitive values locally before the text is used with AI. Original values and restoration mappings remain on your device. With Protect, you choose where to use the protected text. With Pro, reviewed protected content temporarily transits through Priova’s authenticated managed service, while originals stay local.

Can Layrin work with longer text?

Yes. Layrin can work with longer pasted text. Review remains important, and detection is not guaranteed to be perfect.

Does Layrin replace my AI tools?

Protect works with the AI tools you already use. Pro adds an integrated AI workflow inside Layrin.

Is Layrin a browser extension?

No. Layrin is a desktop app built around a local protection workflow before you use AI.

Where do I manage my account?

On layrin.com. The desktop app stays focused on protection and restore, while account and access details stay in your dashboard.
