Frequently asked questions
What is prompt engineering?+
Prompt engineering is the practice of crafting instructions for AI models so they produce accurate, useful, and consistent results. Small wording changes can dramatically improve output quality.
Which AI models does PromptIQ work for?+
PromptIQ helps you write better prompts for any modern LLM — ChatGPT, Claude, Gemini, Llama, Mistral and others. The principles it analyzes are model-agnostic.
Why is my prompt scoring low?+
Low scores usually come from missing context, vague goals, no audience or tone, no format spec, or no constraints. The 'weaknesses' section pinpoints what's missing.
Is PromptIQ really free?+
Yes. No login, no signup, no paywall. If you find it useful, you can support development via the donate button.
Does PromptIQ store my prompts?+
No. Prompts are sent to the AI provider only to generate the analysis and are not stored on our servers.
Can I use it for business?+
Absolutely. PromptIQ is great for marketing teams, agencies, developers, and founders who want consistent, high-quality AI output across their workflows.
What is the Idea → Prompt feature?+
Describe your goal in plain language (e.g. 'write a cold email to a SaaS CTO') and PromptIQ writes a complete, professional prompt for you, plus an explanation of why it works.
