How it works

Three steps,
no magic.

Vous gardez la décision à chaque étape. L’agent ne pseudonymise rien sans que vous ayez vu, validé et donné le feu vert. Le pseudonymat est réversible : vous pouvez restaurer l’original à tout moment depuis votre coffre.

And then, inside the AI

The AI reasons on codes.
You alone read in clear.

Paste the pseudonymised document into Claude, ChatGPT or Mistral: the AI analyses the case without ever seeing a real name. With one click on Clear read, the Docult extension restores the original values, in your browser, without sending anything back to the model.

Pseudonymised document detected — analysis on codes

From the file name (…_redacted.docx), I can see this document is pseudonymised via Docult. I reason on the roles while keeping the codes intact, without trying to recover the original values.

Why Docult

Built for professionals who do not compromise on confidentiality.

Law firms, DPOs, legal teams, HR and healthcare teams need a serious tool when they handle personal data, not a generic cloud feature bolted onto another editor.

Docult AI engine · built in-house
The engine was designed by Docult for legal pseudonymization. It runs on our French infrastructure: your documents never leave the sovereign perimeter.
Réversibilité du pseudonymat
Restaurez l’original à tout moment depuis votre coffre chiffré, gratuitement. Le pseudonymat n’est jamais une route à sens unique.
No subscription, credits only
Tiered pricing by page volume (e.g. 40-page PDF = 8 credits). Buy when you need — launch offer −50% on top-ups. Non-expiring credits.
Vitesse et simplicité
2 clics pour pseudonymiser. L’agent annonce le coût avant chaque opération, vous validez, c’est fini. No installation.
Spécialisé droit
Designed for French legal structures: contracts, pleadings, case files and deeds. It understands legal language and is not a general-purpose assistant.
Audit signé pour la conformité
Chaque pseudonymisation génère un rapport d’audit signé numériquement. Conforme RGPD, opposable en cas de contrôle CNIL.
L’écart est mesurable
