SumRize

SumRize is a Chrome extension built around a simple two-step idea: summarize a YouTube video, then turn that summary into a presentation. You open a video in Chrome, click the extension icon, and SumRize reads the available English subtitles to extract the key points. From the same small popup you can then download a PowerPoint file that lays those points out slide by slide.

The stated audience is students, educators, professionals and lifelong learners who want to cut down note-taking time and reuse video content in a presentation format. According to the extension's own description, English-language summaries are the only option currently available, and the video must have English subtitles for the extension to generate anything.

SumRize is a small, single-developer project published by Weekend Projects Lab, and it is free to install from the Chrome Web Store. Treat it as a convenience tool for fast comprehension and quick slide drafting rather than a polished presentation designer — you will still want to clean up and restyle the exported deck.
