What partners ask first.

Where does my data go?

Client data sits in a dedicated tenant, encrypted at rest and in transit. Nothing is used to train models. Full data residency options for US and UK. SOC 2 Type II.

Does it hallucinate?

Every output Lucio produces is grounded in the documents you uploaded and cited back to the source line. If the answer isn't in the file, Lucio says so. No invented authority or fabricated quotes.

Can I rely on it for filings?

Lucio is a research and drafting accelerator. The lawyer signs the brief. Every citation Lucio surfaces is verifiable in the record before it goes anywhere near a court.

Built for the team the business depends on.
