ONYRI Sanitize
Get the most out of AI without handing them your data.
Most AI-privacy tools redact on their servers — your data still leaves your machine. ONYRI Sanitize doesn't: detection, masking and restoration run 100% in your browser, and the token↔value mapping never touches a server. 0 bytes of sensitive data ever leave. What stands out: • Reversible tokens, not black boxes — the AI keeps context; you restore values in place • 38 detectors, 6 families: names to API keys, salaries to cloud secrets • Text, CSV/Excel + built-in Chat for GPT, Claude & Mistram
Hey Product Hunt 👋
I'm Alex, maker of ONYRI Sanitize.
This started with a small, scary realization: a single copy-paste can leak your company's most sensitive data — for good. You drop a customer export, a support ticket or an HR spreadsheet into an AI to "just rewrite this," and names, IBANs, salaries, even API keys leave your perimeter with no way back.
The usual fix is a server-side gateway that redacts your text — but that means your data still travels to someone else's machine first. That felt backwards.
So ONYRI Sanitize does the opposite: the whole engine runs in your browser. It detects 38 types of sensitive data across 6 families (from a name to an AWS key), swaps each one for a reversible token, and you send only the clean text to the AI. When the answer comes back, the tokens turn back into your real values — locally, in place. The token↔value mapping never touches our servers. 0 bytes of sensitive data leave your device.
A few things I'm proud of:
• Reversible, not just redacted — the AI keeps context, so the answer is actually useful.
• Works on text AND tables (CSV/Excel), column by column.
• A built-in Chat to talk to GPT, Claude, Gemini or Mistral with anonymization applied automatically.
One honest caveat: no detector catches 100% of everything. So every detection is visible and editable before you send, and you can add your own rules for the patterns specific to your work. You stay in control.
There's a Free tier to try it on real text right now, and Pro/Team plans for daily use.
I'd love your help: what kinds of sensitive data should we detect next? Reply with the gnarliest thing you've ever almost pasted into an AI 😅
Thanks for taking a look 🙏
