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.

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.
