Open Brain Tools website is an educational platform designed to help students learn computer science through interactive, hands-on tools.

It focuses mainly on GCSE/KS3-level computing concepts, offering visual and practical simulations rather than just theory. The site includes tools for topics like:

  • algorithms (e.g. sorting and searching visualisers),
  • logic circuits,
  • sound sampling and data representation.

The key idea behind the website is “learn by doing”—users can experiment with concepts in real time, step through processes, and see how systems behave, which makes abstract ideas easier to understand.

In short, it’s a free online resource for teaching and learning computer science interactively, particularly useful for school students and teachers.
