Keep the data useful.
AI can reason with finesse on the anonymized copy. It sees the structure, the context, the relationships between entities. Nothing is lost except identifiers.
We are building the platform that makes AI usable on the most sensitive data: that of law firms, accountants, notaries, and every profession where secrecy is not optional.
In a world where AI has become the default productivity lever, regulated professions face a dilemma: using ChatGPT or Claude on a client file breaks professional secrecy. Not using them means ceding ground to less scrupulous competitors. Neither option is tenable.
Manual anonymization is slow, automatic anonymization breaks context, and the code of existing tools isn't auditable. Meanwhile, the firm's most valuable data (the data that defines its know-how) stays locked away, unusable by AI.
Hexagone AI exists to break this deadlock with a simple promise: keep the data useful, keep the data confidential, make compliance obvious. All without changing a single tool you already use.
