NotMyData
Local masking for LLMs
Use powerful models without leaking PII or contracts.
We check in real time if you're sending sensitive information.
No data stored. Everything runs locally or open-source.
Install as a browser extension and start in seconds.
Un analizador en el navegador identifica PII y datos sensibles (emails, teléfonos, tarjetas, contratos) usando reglas y modelos locales. Nada se sube a servidores.
Los fragmentos detectados se sustituyen por tokens seguros. El mapa de sustitución se guarda temporalmente y solo en tu dispositivo.
El texto llega a ChatGPT/Gemini sin datos reales. Luego, la extensión puede reinyectar tus valores localmente o mantenerlos enmascarados.
Nuestra extensión escanea y enmascara localmente la información sensible antes de que salga de tu navegador. Ni ChatGPT ni Gemini reciben tus datos reales: solo ven marcadores (p. ej., [EMAIL], [DNI], [IBAN]).
