Learning artificial intelligence isn’t easy and probably would never be.

But, it’s more accessible now than ever before, thanks to the availability of online classes.

When it comes to learning, one prime concern of the course takers is - Where to take the course from? Is the course provider reliable?

What can be better than learning from the best universities globally?

We have listed AI courses from the top universities, including the likes of Harvard, MIT & Stanford.

The course content from these platforms goes much deeper on the subject than an average article or video you would have chosen to spend time on.

These online courses are taught by top AI researchers or experts, and are available for free! Take your pick.
