Frequently asked questions
Are paid prompt marketplaces worth it?
Sometimes — for highly specialized verticals. For general use, free libraries (like PromptFusion AI) are equally good.
Can ChatGPT write better prompts than me?
Yes, especially when asked. Try "Improve this prompt so I get a better answer" — it's surprisingly effective.
