An online coding platform

Ancient Brain is an online coding and hosting platform for everyone.
See Intro and List of features.

Coders: Make 3D worlds and share them with friends. Clone and edit other people's worlds. Make touch mobile games. Embed your worlds on other sites.

Teachers: Run courses in coding and coding for kids and AI coding. Run programming practicals in 3D or 2D or text, with many features designed for teachers. Safely edit and run student code.

Learners: Do courses in coding and coding for kids and AI coding. Clone other people's worlds and change one or two lines. What's the worst that could happen?

Gamers: Play the endless game worlds the coders make. Come and browse an ever-growing archive of games.

Researchers: Upload problems, tender for solutions, test and rank them. Make hybrid AI systems from the code of multiple authors.

Enough talk. Show me a video!

OK, here is a high-level introduction.
This does not assume you have ever coded, or ever heard of JavaScript graphics (what is behind this site).

How to code

You can "run" any of the 3,345 programs or "Worlds" by clicking on them. But this is also a coding site, where you can code your own Worlds. You can use this site to learn to code. Or show off your creations if you are an experienced coder.

Click below to learn how to code on this site. Basically, there is a choice of "libraries" that you can use.

How to code

Skip the intro, let us decide the library, and go straight to the starter tutorial (with videos):
