In the pack: ChatGPT, Claude & Gemini Prompts for Writers and Authors
Author Bio in Three Lengths
Prompt
Facts about me (writing credits, relevant jobs, where I live, interests that connect to my books): {{FACTS_ABOUT_ME}}
My books and genre: {{MY_BOOKS}}
The tone I want (warm, wry, serious, mysterious): {{TONE}}
Write three versions in the third person:
1. Short: 35-50 words, for a query letter, a short-story byline or a conference programme.
2. Medium: 80-120 words, for the back of the book or an Amazon author page.
3. Long: 200-250 words, for a website About page or a press kit.
Then write the medium version again in the first person, for my own newsletter or social media.
Rules:
- Use only facts I've given you. Don't add awards, sales figures, degrees or credits.
- Lead with what's most relevant to readers of my genre.
- One personal detail is enough to make it human; don't list hobbies.
- No "passionate about", "avid reader since childhood" or "lives with her cat and too many books" clichés unless I put them in my facts.
Finish with one question about me whose answer would make the bio stronger.
