PRIVACY FIRST

Unlike other PDF apps, Anti-Gravity processes core features entirely on your device. AI features use a secure, transient connection to Google's Gemini—your documents are analyzed in real-time but never stored, never used for training, and immediately discarded after processing.

You control which features use AI. Local PDF editing works completely offline.
