Karel Challenge Online 2026
The online edition of the most exciting programming competition we know is back, and this year you will have more time to take part! The Karel Challenge Online will begin on January 8 and will run until February 21, the day the finals will be held. This means that this year you will have four weeks to practice, try out the game, and attempt to qualify, instead of just one week as was usual. The competition is open to everyone, so it is not necessary to be a Codelearn student to participate.

Faced with this scenario, it’s natural for many questions to arise: Can AI completely replace us? Will it eliminate jobs traditionally performed by people? And does it even make sense for younger generations to learn how to code if artificial intelligence can already do it for them?
