Transform Your Udemy Course Videos into Beautiful Study Notes
Have you ever watched a Udemy course, only to realize later that you can't remember half of what was covered? You're not alone. Studies show that we forget up to 70% of new information within 24 hours without proper note-taking.
NoteSynth is a free, open-source tool that solves this problem by automatically converting your Udemy course videos into well-structured, beautiful Markdown notes you can review anytime.
