Q&A: Your Burning Questions Answered
Q: Can I use these prompts with other AI tools like Claude or Gemini?
A: Absolutely! While they were designed with ChatGPT in mind, the structure and detail will work well with any advanced language model. You might need to make tiny adjustments, but the core request will be understood.
Q: I feel weird about using AI. Is this cheating?
A: Not at all! Think of it this way: are you cheating when you use a thesaurus to find a better word? Or when you read books on plot structure? AI is a tool for brainstorming and overcoming writer’s block. The story, the voice, the emotion, the final words on the page—that’s all you. As noted by writing organizations like the Authors Guild, the key is substantial human authorship, which you will be providing.
Q: The AI gave me 10 ideas, but I only kind of like one of them. What now?
A: Perfect! That’s the goal. Take that one idea and make it your own. Use it as a seed. You can even feed it back into ChatGPT and say, “I like premise #7. Let’s flesh it out. Who is the main villain? What is the inciting incident?” Use the AI as a brainstorming partner to build on the initial idea.
Q: What if the AI’s ideas feel too generic?
A: This means your prompt might need more specificity! Go back to the template and add more detail. Instead of just “secret society,” try “a secret society of immortal alchemists hidden beneath Paris.” The more unique detail you feed the AI, the more unique its output will be.
