LiminaCopy wiki link

Limina is the current name of the company formerly branded Private AI. Its product focuses on detecting and de-identifying sensitive information across text and other media for analytics, sharing, retrieval, or AI workflows. Deployment options include customer-controlled environments in some plans.

De-identification can remove obvious PII without eliminating every contextual or re-identification risk. Accuracy depends on language, domain, entity type, and the cost of both missed and over-redacted content.

In Private AI competitors, Limina is a data-transformation component. It does not by itself make the downstream model, retrieval system, or observability stack confidential.
