Summarize This: Free AI Summarizer for Text, PDF & YouTube

Summarize This is a versatile content-condensing tool built for anyone drowning in information overload. Whether you're staring down a dense article, a lengthy PDF, or a 40-minute YouTube tutorial, this tool extracts the core ideas in seconds so you can grasp the essentials without reading or watching every word. It works across multiple formats—plain text, web page URLs, PDF documents, and YouTube videos with captions—making it a flexible companion for research, studying, and everyday browsing. Beyond the website, Summarize This extends its reach through an iOS app with a system-wide Shortcut Action and a Chrome Extension that adds one-click summarization directly into your browsing workflow. This means you can condense content no matter where you encounter it, without switching apps or copying text back and forth. PDF summarization adds a layer of customization by letting users plug in their own OpenAI API Key, giving more control (and responsibility) over that specific feature. With a freemium structure that includes free basic use plus affordable Pro subscriptions, Summarize This caters to casual users and power users alike. Students cramming for exams, professionals skimming reports, researchers digging through papers, and anyone tired of long-form content will find this tool a practical shortcut to faster comprehension.
