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.
