Comments on ThinkPDF: AI Reader,Quiz, Chat for Android
★★★★★Sufiya Khan· May 30, 2026
Really impressed with Think PDF. The AI features are actually useful, and having all the PDF tools in one place makes things much easier. Clean interface, smooth performance, and no hassle when editing or converting files. Great app overall!
★★★★★J A Khan· May 31, 2026
Finally, a PDF app that actually has all the tools I need in one place! I use Think PDF all the time to merge documents, compress large files, so they fit into emails, and split pages when I only need to send a specific section. The Doc Scanner is a lifesaver for scanning receipts and turning them into professional documents. It’s basically a Swiss Army knife for PDFs. Highly recommend it to anyone who is tired of downloading five different apps just to manage their files!
