Engineer tired of long docs mail reports

About

I grew up in a working-class family and eventually became a PhD electrical engineer. Today I work on improving the reliability of railway infrastructure. Outside my day job I enjoy solving practical problems. Like many people, I receive a constant stream of emails, reports, contracts, invoices and official letters. Understanding them often takes far longer than it should, especially when one also needs to watch out for phishing or scams. Some time ago I started build apps, usually late in the evening after my daughter has fallen asleep. What began as curiosity slowly turned into something real. ExplainThisDoc grew out of that process. I tested it on hundreds of my own documents, and it helped me so much that I decided to share it with others.

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.
