Can I learn to kitesurf alone?

NO

For those who do not follow or know the safety regulations, kitesurfing can be a very dangerous sport.

Kitesurfing courses are necessary to know well the theoretical bases of how the kite works, the safety measures, and the rules of preference in the water. The worst causes of accidents arise from people trying to learn alone or with the help of an inexperienced person. In addition to being dangerous, it may take a while to evolve to the level of what an instructor can do in a relatively short period.
