How to Use the Prompt Variable Templater & Replacer

  1. 1 Write or paste a prompt template using {variable_name} or [tag_name] placeholders.
  2. 2 The tool automatically scans your text and generates clean input fields for each unique variable.
  3. 3 Type your desired values into the input fields and watch the prompt assemble reactively.
  4. 4 Copy the completed prompt with one click.

Methodology & Algorithmic Standards

Executes non-greedy regex token scanner (`/{([a-zA-Z0-9_-]+)}|[([a-zA-Z0-9_-]+)]/g`), extracts unique variable keys, dynamically constructs reactive state bindings, and replaces tokens in real time.

Frequently Asked Questions

What placeholder syntax is supported? ▼

Supports standard curly braces `{variable}` and square brackets `[variable]`. Identifiers can include letters, numbers, hyphens, and underscores.

What happens if a variable is used multiple times in the prompt? ▼

Duplicate variables share a single input field. Updating the field synchronizes all occurrences across the prompt simultaneously.

Can I export the populated prompt to Olevx Notepad? ▼

Yes! Click "Open in Notepad" to create a fresh note with your generated prompt ready for testing.
