Templates you create are saved in this browser only. Use Export to JSON in the menu to back them up or add them to a collection file.

    Template syntax

    Write a prompt as normal text and mark the parts you want to change with placeholders. Each placeholder becomes a field in the form.

    FieldWrite it asExample
    Text[Label:Default][Subject:camping tent]
    Number#Label:Default##Focal Length:35#
    Choice{Label:One;Two;Three}{Time of Day:Night;Sunrise;Sunset}

    Good to know

    • The label is the field name. It can't contain a colon.
    • For a choice, the first option is the default. Separate options with semicolons.
    • Placeholders must fit on one line. Text outside placeholders can be as long as you like.
    • Brackets without a Label: part, like [1], are left as plain text.
    • The prompt updates as you type. Reset restores the defaults, and Copy link shares the template with your current values.
