From your inputs to a usable result
01
Bring your template
Paste a template using {{name}}, ${name} or [[name]] placeholders. Escaped placeholders remain literal.
02
Check each variable
Choose a target syntax and supply values. Missing values and conflicting duplicates stay visible before rendering.
03
Export the checked text
Download the converted template or rendered text as TXT. Keep a JSON backup to edit the project later.
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.
