Naosuu
Protect client data by redacting prompts locally before using AI
Naosuu protects sensitive information when you use AI. It intercepts prompts in your browser, replaces PII and confidential data with labeled placeholders, and restores the real values in the AI’s response—all done locally on your device. No originals are transmitted or stored on servers.
Use it to redact typed prompts or uploaded PDFs and Word files before pasting into ChatGPT, Claude, or Gemini. You can review detected entities, set aliases, and keep a session-only placeholder map. Simple pricing with a 30-day free trial.
