Free AI Courses on Udemy, Organized by Topic
Quick answer
Udemy’s free artificial intelligence courses are split across ten topic hubs. Click through to any topic below to see Udemy’s current live list of free courses and free preview lessons for that subject. We link directly to Udemy rather than naming individual courses, because most “free” Udemy courses are 100% off promotions that run out within days, and a course that’s free this week may not be free next week.
How Udemy’s free courses actually work
Two different things get called a “free Udemy course,” and it matters which one you’re looking at.
- Free preview lessons: Udemy lets anyone watch a handful of short video lessons from a paid course without paying, usually to help you decide if the full course is worth buying. These are always free and don’t expire.
- 100% off coupons: Instructors regularly release limited time coupons that make an entire paid course free. These can run out in days or hours, so any fixed list of free courses tends to go stale fast.
Because of that second point, the topic links below are the most reliable way to find what’s actually free on Udemy today, rather than a screenshot of what was free when this page was written.

Udemy issues a certificate of completion for finishing a course, free or paid. It’s useful for showing you did the work, but it isn’t an accredited qualification the way a university degree or a vendor certification exam is. If you specifically need a recognized credential, read our guide to free AI courses with certificates that are actually worth listing on a resume.
