Quick answer

These prompts cover every stage of a business plan. Replace the [brackets] with your details, use them one at a time, and always ask the AI to flag anything that needs a source. Good prompts give context, a role, a clear task and an output format.

How to write a good prompt

Every strong prompt has four parts: context (your business), role (who the AI should act as), task (exactly what to produce) and format (table, bullet list, word limit).
