How it works

Write a prompt once. Mark the variable parts with {{placeholders}} so you can reuse it later.
Step 2
Fill the fields
Open the prompt and fill in the placeholders. Live preview shows the final text as you type.
Step 3
Copy and paste
Copy the finished prompt and paste it into ChatGPT, Claude, Gemini or any other LLM.
