How to use it
Review the example and field labels, enter your input, then select Process. The result appears below. Use Restore example to return to the initial settings.

Frequently asked questions
Can I save my result?
Run the tool, then use its download control. Text results can be saved as a file; image and audio tools show their available export links after generation. A disabled download means a new result is needed.
Are my inputs uploaded?
The tool processes your input in this browser tab. Opening the page downloads the site assets; your tool inputs are not sent to a processing server. Save your result before closing the tab.
How do I start again?
Use Restore example to reset the editable fields, then run the tool again. Changing input invalidates the previous export so that you can generate a fresh result.
