WHY DOCMASTER BEATS THE COMPETITION

Most PDF apps send your files to a remote server to process them. DocMaster does everything locally — your confidential documents, tax returns, medical records, and contracts stay on your phone.

Most AI PDF tools require a cloud subscription at $10–20/month. DocMaster includes on-device LLaMA 3.2 AI at no extra cost.

Most PDF apps are either too simple (just a viewer) or too bloated (dozens of features you never use behind a paywall). DocMaster gives you the complete professional toolkit without the subscription wall.

• Professionals who sign and edit contracts on the go
• Students who want to summarize lecture notes and research papers
• Small business owners managing invoices and forms
