CODE STUDIO / FIRST EDITION

Draft JavaScript for Node.js or Python. Copy your code or download a file, all within this browser tab.
EDITOR ONLY · NO EXECUTIONChanging this selection does not replace your draft. Load starter replaces it only after confirmation if you have edited it.
Select lines or place the cursor on a line, then use the indentation buttons. Tab still moves keyboard focus. Undo: Ctrl/Cmd+Z. Redo: Ctrl/Cmd+Shift+Z or Ctrl+Y. History is temporary and limited to 50 states; older states may be dropped sooner for large files.
Open file reads a UTF-8 .js or .py file locally (maximum 1 MB). Downloads create a separate file; your original is never overwritten by this app. Plain-text editor, not full VS Code. No terminal, syntax checking, package installation, or code execution. Your code stays in this browser tab. The app does not send it to a server or save a draft; closing or reloading can lose your draft. Click Download file to keep a copy on your computer. Extensions, device access, and clipboard content are outside this guarantee. Avoid credentials. Downloaded code is not checked for safety.
Preflight Review — check before running

Look for warning signs in the code without running it. Start by marking the actions you expect below, then click Inspect code. This tool checks text patterns, not everything the program could do. It can flag harmless text or miss real risks. No warnings does not mean safe.
Review needed. No code is executed.
Reports contain a code hash, rule version, declared permissions, findings and limitations—not source code. Reports may still reveal capability information; review before sharing. All processing stays in this browser tab.
