PDF Editor & AI: Anti-Gravity

PDF toolkit for Android — merge, split, compress, scan, sign and edit documents. No watermarks, no sign-in, no file size limits.

Anti-Gravity is an all-in-one PDF toolkit designed for students, professionals, and anyone working with documents.

With 20+ tools in a single app, you can handle every PDF task without switching between multiple applications.

HYBRID PROCESSING ARCHITECTURE

Unlike traditional PDF tools that upload all files to remote servers, Anti-Gravity uses a privacy-first hybrid approach. Core PDF tools process documents locally on your Android device so files remain on your phone. Advanced AI features use secure, transient cloud processing to provide high-performance analysis without compromising your long-term privacy.
