From detection to restoration

Marvin Systems aims to be as Plug and Play as possible: Every step of your document anonymization pipeline, in one place.
  • Automated detection

    Marvin Systems automatically understands the context of every document and combines in-house NER, custom rules and open-weight LLMs to maximize the accuracy and versatility of detected data.

  • Edition & validation

    An intuitive editor lets you fine-tune which data gets anonymized and confirm the complete absence of leaks before export — zero-compromise confidentiality.

  • Anonymization

    The redaction engine fully cleans anonymized data (not just a rectangle on top of the PDF) and groups occurrences of the same real-world entity for consistent, reusable output.

  • Content restoration

    When a third party mentions pseudonyms in a reply or a document, restore the original values in a click — removing every friction point tied to anonymized outputs.
