The app includes a free trial, with upgrade options to Premium (PDF & Docs) or Platinum (Premium plus AI).

• Free Trial (3 days): View all supported formats and explore core tools. After the trial, viewing common formats stays free; advanced tools require an upgrade.

• Premium — for everyday PDF & Docs needs: Unlock all non-AI features: edit, annotate, merge/split, convert, create/fill forms, sign, and print/export.

• Platinum — Everything + AI: Includes everything in Premium plus AI, powered by the most advanced ChatGPT model. Because AI uses ongoing compute, Platinum is offered as a subscription.

• AI Trial for Premium users (30 or 7 days): Try PDF Infinity AI—Smart Summary, Outline Builder, Find & Explain, and Ask Anything—with clear page references. When the AI trial ends, AI access requires Platinum.
