I was spending 40+ hours on online courses and getting frustrated. Built-in speed controls were terrible — 3-4 steps, no keyboard shortcuts, reset every session. Existing extensions weren't designed for course platforms. CourseSpeed started as a personal script, then grew into a full extension with per-platform speed memory, AI notes, analytics, and bookmarks. Two features I'm proud of: 1. AI notes that capture audio and generate timestamp-linked study notes 2. Learning analytics that show your real efficiency — not just "hours watched" Research backs this up: Murphy et al. found 2x speed causes no learning loss, and watching twice at 2x gives better retention than once at normal speed. Ask me anything about building Chrome extensions, the science of video speed, or online learning!
