To write a business plan with AI, use it to structure and draft each section from your inputs, then replace assumptions with real research and numbers. AI gives you a fast first draft, not a finished plan.

Structure and draft

Ask a general assistant for a business-plan outline (summary, market, product, marketing, operations, financials), then draft each section by feeding it your real details — your idea, customers, pricing and goals. It turns scattered thoughts into a structured draft quickly.

Make it real

AI will fill gaps with generic assumptions, so replace them: do real market research (use Perplexity for sourced data), put in your actual costs and realistic projections, and ground claims in evidence. A plan built on invented numbers helps no one.

Verify and own it

AI can fabricate facts, figures and citations with total confidence (a “hallucination”). Treat AI output as a draft and verify anything important against a reliable source — this matters most for medical, legal, financial and academic use. AI can invent market sizes, statistics and competitor details, so verify every figure and claim. Treat the plan as yours — investors and lenders will question it, and you need to understand and defend every number. Use AI to draft and organise, not to fabricate.
