Naosuu

Review and replace confidential values before sending prompts to AI

Meet Naosuu

Naosuu helps people review sensitive information before sending a prompt to ChatGPT, Claude, or Gemini. It detects values such as names, organizations, financial figures, identifiers, and matter references, then replaces selected values with placeholders. Related references can share the same placeholder so the request retains useful context.

When a response returns, Naosuu restores the original values on the user's device. Detection, mapping, and restoration happen locally, with a review step before information is sent. The product is designed around confidential document and legal workflows and offers individual subscriptions with a trial. Users still need to check the proposed protections, since detection can miss sensitive details.
