Tenebrae Guardian

Tenebrae Guardian puts AI privacy in your pocket. The Guardian keyboard checks what you type before it reaches any AI assistant for sensitive data like Social Security numbers, credit cards, passwords, and API keys. When it spots something, it warns you and lets you hide it with a single tap, swapping the real value for a safe placeholder. Everything the keyboard inspects stays on your device. The Guardian keyboard runs entirely on your device. It has no Full Access and makes no network calls — your keystrokes are never sent to us or anyone else.

Note: the hosted Tenebrae Solo API (used by your automated workflows) is a separate, server-side service. The on-device Guardian keyboard transmits nothing; see our privacy policy for how each part handles data.
