AI Prompt Template Builder
Create reusable prompt templates with {{variable}} placeholders. Fill in the values, preview the result, and copy to any AI tool.
Use {{variable_name}} for placeholders
Type a template on the left to auto-detect variables.
Frequently Asked Questions
What is a prompt template?▼
A prompt template is a reusable text structure with {{variable}} placeholders. Instead of rewriting prompts from scratch, you define the shape once and fill in the variables. Useful for batch processing, team-wide prompt libraries, and consistent AI outputs.
What syntax does this tool use for variables?▼
This tool uses {{variable_name}} double-curly-brace syntax, which is common in Handlebars, Jinja2, and LangChain. Variables can be any alphanumeric string with underscores. Example: 'Write a {{tone}} email about {{topic}}.'.
Can I use this with ChatGPT, Claude, and Gemini?▼
Yes. This tool generates the filled text string — paste it directly into ChatGPT, Claude.ai, Gemini, or any API client. It doesn't call any AI API; it just builds the text locally in your browser.
How do I save my templates?▼
Use the Export JSON button to download your template as a JSON file. Load it back with the Import button. You can also copy the raw template text and store it in Notion, GitHub, or any text editor.
