Templates and Variables

Write a prompt once, use it a thousand times with different inputs.

Turn any prompt into a reusable template by wrapping dynamic parts in double braces: {{customer_name}}, {{tone:select:formal,casual,technical}}. Promptmark parses the syntax, infers types, and builds a form for filling in values.

Five variable types cover the common cases: text, multiline, number, select, and boolean. Templates render through the web UI, the MCP tools, and the REST API.
