ThinkPDF - 20+ offline PDF tools & local AI chat in one app.

by•
ThinkPDF is a privacy-first "Super App" for your documents. It combines 20+ offline PDF tools (Merge, Compress, Smart Scanner, E-Sign) with a powerful AI Assistant. Instead of expensive cloud APIs, it uses a Local RAG pipeline to let you chat with and summarize PDFs directly on your Android device. Zero login required, no forced subscriptions, and your private files never leave your phone.

Hi Product Hunt! 👋 I’m Zulkar, a Data Scientist and the maker of ThinkPDF. Dealing with technical papers and documentation daily, I realized my workflow was a mess. I was using sketchy ad-filled websites to compress files, a separate app to scan notes, and avoiding $20/month AI wrappers just to get a simple document summary. I decided to solve my own problem and built a unified, privacy-first Android app using Flutter. 🧰 The Utility Belt: I built 20+ offline tools into the app so you never need another PDF editor. It includes Merge, Split, Compress, Password Protect, E-Signature, and an ML Kit-powered Document Scanner. All of these run completely offline. 🤖 The AI Engine: To keep the app affordable and secure, I implemented an optimized Local RAG (Retrieval-Augmented Generation) pipeline. The app chunks and searches your text locally on your device, meaning your private documents are never uploaded to a cloud server for training. I would absolutely love your feedback on the UI/UX. Did I pack too many tools into one interface, or is the navigation intuitive? Let me know your thoughts!
