The Claude AI Prompt Book

Claude can write, plan, explain, research and build things for you, but the answers you get depend on how you ask. This book gives you 300 ready-to-use prompts with simple blanks to fill in, organized by the jobs you actually do, plus the method behind them so you can write your own for anything.

The BRIEF formula is a five-part way to write a strong prompt for any task (Background, Request, Ideal result, Examples, Follow-up), with before-and-after examples. The 300 prompts cover email and everyday writing, work and productivity, small business and marketing, careers and job search, learning and study, research and decisions, money, home and family, health questions, creative fun, and building documents, spreadsheets, slides and simple apps.

There's a Quick Fixes table for when an answer is too long, too vague, too formal or possibly wrong, a chapter on the Claude features worth knowing (checked in October 2026), safety notes on what never to paste into a chat, a one-page cheat sheet and an A-to-Z Prompt Finder. Every prompt was tried out on Claude with realistic details before publication.

You get a 200-page PDF to read or print and an EPUB for phones and e-readers. An independent guide: not affiliated with, sponsored by or endorsed by Anthropic.
