Right-click menu appears only when you select valid JSON One-click conversion to Toon format Instant “Copy Toon” with success feedback Fully offline – no data leaves your browser Built-in popup for manual paste & convert Dark-mode friendly, minimalist UI Perfect for Prompt Engineers, Cursor/Claude users, and anyone optimizing structured data for ChatGPT, Claude, Gemini, Grok, etc.
