FAQ
Does Prompt Mirror call an AI model?
No. It applies local structure rules in your browser and does not send the prompt to an AI service.
When should I add a role to a prompt?
Add a role when it clarifies the perspective, audience, or quality bar you want the model to use.
Can I use this for reusable prompt templates?
Yes. It is useful for turning rough asks into clearer role, task, format, and constraint sections.
