PseudoStudio isn't just a text editor—it is a fully functional cloud compiler designed to execute theoretical computer science algorithms exactly as they appear in your textbooks.
Type your algorithm into the main.pseudo window using standard Cambridge/IB syntax. Click Run Code, and our backend engine will process your logic. If your program asks for data using the INPUT command, type your response directly into the blinking Interactive Terminal.
Our online compiler strictly adheres to the official formats used in major exams. We support full logic processing including IF/THEN/ELSE conditions, nested FOR/WHILE/REPEAT loops, 1-dimensional and 2-dimensional ARRAY structures, and complex string manipulation.
Switch to Pro Mode at the top of the editor to enable our dynamic linter. The interpreter will proactively flag syntax errors—such as unclosed loops, missing ENDIF statements, or incorrect assignment arrows—before you even hit run, helping you write flawless code.
DECLARE MyVar : INTEGER
MyVar ← 10
IF X > 5 THEN
...
ENDIF
CASE OF X
>= 90: OUTPUT "A"
OTHERWISE OUTPUT "B"
ENDCASE
WHILE X < 10
...
ENDWHILE
FOR i ← 1 TO 10
...
NEXT i
INPUT MyVar
OUTPUT "Result: ", MyVar
