Frequently Asked Questions
What does the AI Prompt Optimizer do?
It converts a casual or vague request into a structured prompt with four sections — Goal, Context, Requirements, and Output Format — so AI tools produce more accurate, consistent results.
Does this tool call an AI API?
No. All optimization runs locally in your browser using text analysis rules. Nothing is sent to ChatGPT, Claude, or any external service.
What are the four prompt sections?
Goal states what you want accomplished. Context provides background and audience details. Requirements lists constraints, tone, and must-haves. Output Format specifies how the response should be structured.
Can I edit the output before copying?
The output is generated automatically, but you can copy it into any text editor and adjust before pasting into your AI tool.
Is my text stored or sent anywhere?
No. Your prompt never leaves your device.
Is this tool free and does it work on mobile?
Yes on both counts. The AI Prompt Optimizer on draft21 is completely free with no sign-up required and works on all devices.
