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 [email protected] (SSN 123-45-6789) about the Q3 renewal.
Works with every AI
ChatGPT, Claude, Gemini, Perplexity, and any future tool — one extension, all providers.
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.
