ONYRI · Sanitize

Use any AIwithout giving away your data.

ONYRI Sanitize finds the private bits in your text — names, emails, card numbers — and hides them before you send anything to an AI. The real answer comes back to you, complete. Everything happens on your computer. Nothing is sent.

Coverage

What ONYRI strips from your promptsbefore they ever reach the AI.

38 types across 6 families. Three areas to protect — framed by what you no longer want leaving your machine.

  • For your contacts

    No identifiable person leaves your browser.

    Names, emails, phone numbers, IBANs, social security numbers, addresses, ID documents, medical information.

    • Personal data
    • Bank details

  • For your systems

    No technical secret leaks to the AI.

    AWS · GCP API keys · OpenAI, Stripe, Anthropic keys · Slack tokens · inline passwords · SSH keys.

    • Passwords & secrets
    • API keys & tokens

  • For your company

    No strategic information passes through the AI.

    Internal project names, infrastructure URLs, meeting markers, salaries, company IDs, client and partner names.

    • Strategy & projects
    • Company identifiers
The blind spot

A single copy-paste is enough to leak your data.

Pasting a customer export, a support ticket or an HR spreadsheet into an LLM sends it outside your perimeter — with no way back. ONYRI steps in before that send.

Without ONYRI

Names, IBANs, API keys and internal decisions leave the company in the clear. Once sent, they don't come back — and you have no control over how they're used.

With ONYRI

The AI only ever sees anonymous tokens. You keep the mapping — locally — and the full response comes back on your side.

How it works

Three steps, and none of them leaves your machine.

  1. 01

    Detect

    13 detectors plus your own rules spot sensitive data, live, as you paste your text.

  2. 02

    Tokenize

    Each value becomes a reversible token. The text, now clean, can go to the LLM of your choice.

  3. 03

    Restore

    Paste the model's response: tokens turn back into your original data, exactly in place.

What ONYRI does

An anonymization engine, built for real work.

  • 38 types detected

    Six families: personal, financial, passwords, API keys, company, strategy. Coverage designed for both French and international contexts.

  • Custom rules

    Add your own patterns (internal references, business identifiers) with a regex and a dedicated color.

  • Text and tables

    Paste text or drop a CSV / Excel file: tokenization applies column by column.

  • Large volumes

    Beyond 1,000 rows, processing moves to a dedicated worker: the interface stays smooth.

  • Reusable profiles

    Save a combination of detectors and rules, and replay it in one click every session.

  • Team workspaces

    Share rules and profiles across a workspace: the whole team applies the same policy.

By profession

Built for the professions the GDPR watches

  • DPO & compliance

    You're responsible for the processing. ONYRI minimizes personal data before every AI use — a concrete step toward article 5.1.c.

  • Human resources

    Résumés, contracts, reviews: employee data is the most sensitive. Anonymize it before pasting into an AI.

  • Healthcare

    Health data (article 9) and medical confidentiality. Remove patient names and identifiers before any prompt.

  • Lawyers & accountants

    Professional secrecy and client data. Mask names, case numbers and amounts before the AI.

  • Founders & freelancers

    You use AI every day, with no compliance team. Cut your exposure in one move, without switching tools.

The real questions

What you're wondering, straight up.

Does my data go through your servers?
Never. The server only serves the application. No text, no file, no token ↔ value mapping is ever sent to it.
What if I close the tab?
The mapping lives in memory and disappears on refresh. That's intentional: nothing is persisted, so nothing leaks.
What if the engine misses something?
You stay in control. Detections are visible and editable before export, and your own rules cover the cases specific to your work.
Can my team work with the same rules?
Yes. Rules and profiles are shared per workspace: everyone applies the same anonymization policy.
