Great app for learning coding from scratch. Interactive tasks, cool projects and an AI assistant that always helps. I feel like I'll finally master Python. Highly recommend!
I liked that there are real projects and the opportunity to get a diploma. Sometimes there are minor bugs in the interface, but overall it's not critical. The content is very high quality, and gamification helps not to give up.
Super convenient to learn at your own pace! The interface is intuitive, lessons are well-structured. In a month I completed two courses and I'm already writing my first project. Thanks to the Kodik team!
I've been looking for a platform with such a presentation of material for a long time. Everything is simple and accessible, even for a complete beginner. I especially like the interactive tasks and the ability to see the result immediately.
As someone who has tried many different courses — this one really works. No fluff, just practice. The AI assistant sometimes saves you when you get stuck. Recommend!
I've been looking for such a resource for a long time, where you could not just read theory, but immediately apply knowledge in practice. In Kodik this is implemented 100%. Plus the community is super!
