AI business plan generators have matured significantly. What started as glorified ChatGPT wrappers has evolved into sophisticated platforms that can produce genuinely useful business planning documents. But there's an important question that most "best business plan generator" articles skip: should you be writing a business plan at all yet?
This article covers both angles — the best AI business plan generators available and why the smartest founders validate feasibility before they start planning.
Why Feasibility Before Planning Matters
A business plan is an execution roadmap. It assumes you've already decided to proceed and focuses on how to succeed. A feasibility study asks whether you should proceed at all.
Writing a business plan for an idea that isn't viable is like planning a road trip to a destination that doesn't exist. The plan might be excellent — detailed itinerary, budget, packing list — but it's worthless because the premise is flawed.
The statistics reinforce this. The top causes of business failure — insufficient market demand, poor financial planning, cash flow problems — are all issues that a feasibility study is specifically designed to catch. A business plan that's built on unvalidated assumptions about market size, pricing, and costs is a beautifully formatted recipe for failure.
The recommendation: spend $200 and 8 minutes on a feasibility study first. If the NPV is positive, the IRR meets your hurdle rate, and the sensitivity analysis shows resilience to downside scenarios, then invest the time and money in a comprehensive business plan. If not, you've saved yourself weeks of wasted planning.

The Optimal Approach
The founders who consistently make the best decisions follow this sequence:
Step 1 — Feasibility Validation ($200, 3 minutes): Run a SimpleFeasibility Simple Report to get real market data, NPV/IRR analysis, and a go/no-go recommendation. Test multiple concepts if you're choosing between ideas. Step 2 — Scenario Optimisation ($500, 8 minutes): If Step 1 is positive, run a Complete Analysis. Use the interactive What-If analyser to optimise your concept — find the best pricing, the right scale, the ideal location. Step 3 — Business Plan ($15–$2,000, hours to days): With validated feasibility and optimised assumptions, build your business plan using the tool that best fits your needs — ProAI for comprehensive plans, Upmetrics for collaboration, LivePlan for bank applications, or SimpleFeasibility's Full Business Plan tier for plans with integrated financial analysis.This approach ensures you never invest days planning a business that won't work, and that when you do plan, your assumptions are grounded in reality.
