How it works

Human control where it matters. Automation everywhere else.

The tool detects sensitive content, shows what it will change and checks the protected copy before download.

Prepare the copy in four steps.

The same workflow works for one file or a batch.

Illustrative mapping. The vault is an encrypted file that keeps the link between identities and codes. Save the updated vault and its password on your device. Never send them to the AI.

Only information with a saved mapping can be restored. Solid PDF masks and deleted information are irreversible. Pseudonymised data can still be identifiable through context; it is not guaranteed anonymous.
