The tool runs directly in the browser and is ready for quick checks without installing software.

Input can be cleared and recalculated immediately, which is useful for repeated small tasks.

Use fullscreen mode when you need more space for long text, structured data or large result blocks.
✓
Copy buttons are available on generated output so results can be reused in code, documents or support chats.
