AI Prompt Builder
Write a prompt template using {{double curly braces}} for anything you'll want to swap out, then fill in the fields that appear below.
Variable names can contain letters, numbers, spaces, and underscores. The same name used twice fills in both places at once.
About this tool
A prompt template separates the reusable structure of a good prompt (the instructions, tone, and format) from the specific details that change each time you use it. Writing the structure once and swapping in details through fields is faster and more consistent than rewriting a full prompt from scratch every time, and it's easier to spot what changed between two versions.
How variables work here
Anything inside {{double curly braces}} in the template becomes a fill-in field automatically. Leave a field blank and the final prompt keeps the placeholder text as-is, so it's obvious at a glance what still needs a value before you copy it out.
Good template habits
Keep variable names short and descriptive ({{audience}} rather than {{a}}), and put format or length constraints directly in the template text rather than as a variable, so they're never accidentally left blank.
