Why Choose Oh My Course for Your Course Collections?

Works with Any Course Folder Structure

Downloaded courses as ZIP files from various sources? Oh My Course handles them all. Whether it's Udemy-format courses, Coursera archives, or any structured course folders, our web-based viewer automatically organizes your lessons and tracks your progress. Just select your course folder from your computer - no upload needed, files stay local.

Your Files Never Leave Your Computer

Oh My Course uses your browser's File System Access API to read your local course folders - just like VSCode or other local-first apps. Your course files stay on your device, nothing uploads to any server. All playback and progress tracking happens locally in your browser. Complete privacy and control over your educational content.

Better Than VLC for Course Folders

Generic video players like VLC can't track which lessons you've completed across 50+ video files. Oh My Course is purpose-built for course folders: automatic progress tracking, lesson organization by section, resume playback from where you left off, and a beautiful interface designed specifically for structured learning. Features like subtitle support, keyboard shortcuts, and multi-course library management.

Manage Your Entire Course Collection

Stop opening multiple folders to find the right video. Oh My Course gives you a unified library view of all your courses, showing completion status, progress percentages, and total duration. Pick up exactly where you left off in any course with one click. Perfect for managing large collections of downloaded educational content.
