What is Summarizethis?

Summarize This is a handy AI tool that helps you get the gist of all sorts of content quickly. It is your personal summarizer for text, PDFs, videos, and even those long Twitter threads. You can either paste in text directly, drop in a YouTube video or Twitter thread URL, or upload a PDF file. The AI then gets to work, crunching the information to give you a nice, brief summary. It’s pretty good with most PDFs, though it might have a hiccup with any that are corrupted. To use it, you’ll need your own Open AI API Key. Don’t worry, though – it doesn’t save your key for security reasons. The tool was built by someone known online as @maail and is offered completely free. Just a couple of things to keep in mind: you’ll need to enter your API key each time you want a summary, and for YouTube videos, it works best if they have captions so the AI can process them efficiently.
