Coursmos

Coursmos focuses on micro-learning, packaging knowledge into 3-minute lessons organized into 11,000+ courses and 50,000+ total lessons. This approach fits busy schedules where short, focused bursts work better than hour-long videos. Topics span programming, web development, mobile apps, and other technical skills.

Ideal for people squeezing learning into commutes or spare minutes throughout the day. The bite-sized format sacrifices depth for convenience, so you'll need to string multiple lessons together to grasp complex concepts, but it's excellent for building habits and learning concepts incrementally.
