FAQ
Common questions
Common questions

What's free and what's Pro?
The full AI Prompt Builder is free - all 12 AI tools, master prompts, starter task prompts, prompt strength scoring, calibration examples, share links, and Fast or Advanced mode. No account required. Pro adds the features that need a backend: your prompt vault to save and sync prompts across devices, full history and versioning, PDF and Markdown export, and team sharing. If you just want to build and use great prompts, Free covers everything.
What is a master prompt and why does it matter?
A master prompt (also called a system prompt or custom instructions) shapes how an AI behaves for an entire conversation. Instead of repeating your preferences every time, you set them once and the AI follows them consistently. It is the most underused feature in AI tools, and one of the highest-leverage things you can configure.
Do I need different prompts for different AI tools?
Yes. Each AI tool has different strengths, formatting preferences, and capabilities. ChatGPT responds well to role-based instructions. Claude excels with detailed context and reasoning chains. Midjourney uses a completely different syntax with parameters like --ar and --s. Our prompts are tuned for each tool specifically.
Can I cancel my Pro subscription anytime?
Yes, cancel anytime from your account settings. No contracts, no cancellation fees. Your access continues until the end of the billing period.
How is this different from other prompt sites?
Most prompt sites sell individual prompts with no context. understandingAI is a complete platform. We teach prompting fundamentals, build custom prompts with AI, and provide a curated library organized by tool and task. Every prompt includes usage notes. The AI builder generates prompts tailored to your exact situation, not generic templates.
