What is udemix?

udemiX is a command line Python tool for downloading full Udemy courses to your own computer, including videos, captions, and course-level resource files. It works by using a cookies.json file that holds your logged-in Udemy session information, which the tool uses to authenticate as if it were your browser and pull the course content you already have access to. The author says the project performs a similar job to an existing tool called the omniget plugin, and was directly inspired by it, while adding downloads of course resources and captions on top. To use it, you install the Python dependencies with pip, then run a single command pointing at the course URL and your cookies file. A range of options let you control the download: choosing which chapters to grab with a filter like chapters 1, 3 through 5, picking video quality from 720p up to 1080p, choosing whether to download captions and in which languages, and skipping course resources if you do not want them. A sample cookies file is included as a template for the expected format. The project is distributed under the GNU General Public License version 3, which means the source code stays free and open, and anyone who redistributes it or builds on it must also keep it open under the same license terms. This tool is aimed at Udemy users who want an offline copy of courses they are already enrolled in, and at developers curious about how browser cookie based authentication and video or caption extraction from a learning platform can be scripted.
