Keep secrets out of
every AI you don’t own.
The Doyna browser extension redacts sensitive data — PII, credentials, internal document names — before it reaches the prompt box of any AI tool your team uses.
Slide the handle.
Summarize the email from REDACTED_EMAIL (SSN REDACTED_SSN) about the Q3 renewal.
Summarize the email from john.smith@meridian.com (SSN 123-45-6789) about the Q3 renewal.
Works with every AI
Any public AI assistant, and any future tool — one extension, every provider.
Pattern + entity detection
Regex for obvious PII (SSN, credit cards, emails) plus entity detection for names and internal document identifiers.
Audit log on-device
Every redaction is logged locally. Nothing ships to our servers — the extension is fully client-side.
Zero friction
Redacts as you type. The prompt goes through cleaned, so the AI still works.
- The same offer as everywhere else on the site: a technical conversation, not a sales call.
Private AI, your way. On hardware you own.
It goes up inside your network in a day, on hardware that stays yours. The same AI everyone else rents, built for the budget you actually have.
