In their own words, as submitted to SaaSHub.


SIMPL is a free interpreted language and IDE that runs pseudocode exactly as it is written. It follows the official Cambridge AS & A Level Computer Science (9618) pseudocode guide, so students can type an exam-style algorithm, press Run and see the result, or an error message in plain words...

As answered by people managing SIMPL Pseudocode and Scratch.
SIMPL Pseudocode's answer
It runs the official Cambridge 9618 pseudocode exactly as students write it in the exam, and wraps it in an IDE built for learning: errors explained in plain words, a debugger, and a trace table filled in automatically.
SIMPL Pseudocode's answer
Most pseudocode tools accept their own dialect. SIMPL follows the Cambridge guide closely, and its strict mode tells you exactly what goes beyond it. It also works offline, needs no installation or account, and comes with a complete manual with exercises and solutions.
SIMPL Pseudocode's answer
Students preparing for Cambridge Computer Science exams and their teachers, and more generally anyone learning to program who wants a readable language without the noise of a professional one.
SIMPL Pseudocode's answer
Students often wrote algorithms on paper with no way to check them. I wanted a tool where pseudocode is simply typed and run, as in the home computers of the 80s, and grew it into a complete language and IDE.
