About Gist AI
Gist AI is a Chrome extension that summarizes web pages, YouTube videos, and PDFs in a single click. It handles PDFs found online as well as files stored on the user's device, though local PDFs must be uploaded for summarization. The extension is described as powered by ChatGPT; for YouTube videos it extracts the transcript first, then summarizes it. A Read More feature lets users open the source passage behind a summary point, and users can jump to relevant moments in a YouTube video. The homepage states there is no limit on content length and that the tool is free.
