Strict pseudocode compiler
Tokenize, parse, validate, and compile structured pseudocode with line-level diagnostics.
Browser pseudocode compiler
PseudoEditor
Write, compile, run, and debug IGCSE-style pseudocode in a full browser editor with docs, flowcharts, terminal output, and workspace saving.
Python execution
Run generated Python directly in the browser terminal, including interactive INPUT programs.
Flowchart support
Switch between source and visual control-flow thinking for decisions, loops, and processes.
Workspace saving
Use local browser storage in development and signed-in cloud workspace sync on pseudoeditor.dev.
Learn while you build
Docs and examples beside the app.
The new pseudoeditor.dev site gives search engines useful learning pages while giving students a direct path from explanation to practice.
Open manualGetting started with PseudoEditor
Open the browser editor, write your first pseudocode program, compile it, and run the generated Python output.
Pseudocode syntax reference
Reference the core pseudocode syntax supported by the browser compiler, including assignment, conditions, loops, arrays, and output.
Variables, input, and output
Learn how PseudoEditor handles declarations, assignment, INPUT prompts, and OUTPUT statements.
IF, THEN, ELSE selection
Use IF statements to branch pseudocode programs based on comparisons and Boolean expressions.

Questions
Is PseudoEditor the same as Pseudocode Compiler?
PseudoEditor is the website and browser home for the Pseudocode Compiler app. The compiler, editor, runner, manual, and workspace tools are available in the browser app.
Can I run pseudocode in the browser?
Yes. PseudoEditor compiles supported pseudocode to Python and runs it in the browser runtime, including interactive INPUT prompts.
Does the browser version save my work?
Local development saves to browser storage. On pseudoeditor.dev, signed-in users can save workspaces with Clerk authentication and Convex cloud sync.
Is this only for IGCSE Computer Science?
The syntax and manual are designed around IGCSE-style pseudocode practice, but the editor is useful for anyone learning structured algorithms.
