Cratecode

In the browser, Cratecode teaches programming through interactive lessons where you write code on the page and get AI guidance as you go.

Cratecode is an AI programming course platform that lets you pick what to learn next instead of following a fixed curriculum.

That non-linear setup suits people who already know a little and want to fill specific gaps, such as one language feature or one concept, without sitting through a full syllabus.

The AI is there to guide you through lessons, and it also fits the homework helper and code assistant side of the category, so you can ask for help when you get stuck.

Lessons are not all written by one team.

Cratecode accepts user-generated content, so the library grows through its community and you can contribute your own material.

That is a plus for variety, though quality will likely differ from lesson to lesson.

Pricing is not something to count on here, so check the site before you plan around it.
