BlackShield

    Intercept your sensitive data before it ever reaches an LLM.

    How it works

    One API call before every model call.

    Put BlackShield between your app and any model endpoint. One request in, sanitized output out.

    // before any LLM call
const clean = await fetch('http://blackshield:3000/detect', {
  method: 'POST',
  body: JSON.stringify({ text: userMessage })
});
const { sanitized } = await clean.json();
