| Description | AI PDF Reader is a free, no-signup web tool that opens a document on screen while AI reads the whole file, summarizes it, translates it, and answers questions in the chat using only the document's own text. It handles PDF, DOCX, TXT, PPTX, EPUB, and FB2 files up to 30 MB, and uses OCR to read scanned or photographed pages. It's aimed at students, researchers, and professionals who need to quickly digest long reports, papers, contracts, or slides — and its main differentiator is that it's entirely free with no paid tier, no account, no page cap, and a side-by-side viewer for verifying every AI claim against the original. | Upword is an AI-powered reading and research assistant that scans long content -- articles, YouTube videos, academic papers, and reports -- and extracts the key ideas into editable summary documents and AI-generated notes. Built for students, researchers, and knowledge workers who read heavily online, it pairs a no-signup Chrome extension with a 'lifelong library' so captured summaries, highlights, and notes stay searchable and reusable. What sets it apart is combining summarization with an AI Copilot chat, an audio player for listening to summaries, and one-click sharing to tools like Slack and Notion. |
