From your inputs to a usable result
01
Inspect your text
Paste text to see its code points, hidden formatting characters and line endings. The source stays available.
02
Preview a deliberate change
Choose an optional normalization form, line-ending conversion or leading BOM removal. Compare the preview before exporting.
03
Keep the evidence
Download a CSV inspection report, the preview as TXT or a JSON project backup. Review language-specific effects yourself.
Before you start
Where is my project saved?
Projects are saved in this browser for this site account. Download a JSON backup before changing devices or clearing browser storage.
Is an AI account required?
No. The text transformations and inspections run in your browser. The app does not send text to an AI service.
Will my original text be replaced?
The tool keeps the source in the project and shows a separate preview. Export the preview only after checking it.
Can I resume later?
Reopen the saved project on this browser and account, or restore its JSON backup. Keep backups in a place you trust because they include your supplied material.
