About

Hey Product Hunt! I’m an electrical engineer who enjoys turning complex problems into practical tools. Alongside my engineering career, I develop ExplainThisDoc, an iOS app for understanding and organizing everyday documents. Inspired by my own paperwork, this side project brings together my interests in useful technology, clear information and privacy.

ExplainThisDoc: The Smart Archive Update - Now keep originals, annotate, sign & understand-in one place

ExplainThisDoc has evolved from just explaining documents into a modern, smart document archive. Keep originals, explanations and your work connected. Highlight, annotate and sign. Link related files and personal notes. Archive without AI, summarize on-device with local AI, or get detailed explanations with Pro analysis. New text review lets you compare recognized text against the original, correct it and share it—all in one workflow.

ExplainThisDoc - Understand Any Document - Understand any document instantly. Detect scams & phishing.

Most AI tools summarize text but don’t help users understand real-world documents. ExplainThisDoc analyzes documents automatically and returns structured insights: what the document is about, whether one needs to act, deadlines, places and potential risks. The app also identifies common phishing and scam patterns in emails or letters. OCR runs on-device so images never leave the device, improving privacy compared to typical document AI tools.
