SimpleFeasibility and ProAI are two of the most capable AI-powered business analysis tools available in 2026. But despite appearing in the same category, they serve fundamentally different purposes — and choosing the wrong one means getting an excellent answer to the wrong question.
ProAI generates business plans. SimpleFeasibility generates feasibility studies. That distinction matters more than you might think. This comparison breaks down exactly what each tool does, where they overlap, and which one you should use depending on what you're trying to accomplish.
The Core Difference
The simplest way to understand these two tools:
ProAI answers: "Here's how to build and run this business." SimpleFeasibility answers: "Should you build this business at all?"ProAI produces comprehensive business plan documents — operational roadmaps with marketing strategies, management structures, P&L projections, and pitch-ready formatting. It's designed for founders who have already decided to proceed and need a plan to execute against or present to investors.
SimpleFeasibility produces feasibility analysis — market validation with real data, investment-grade financial metrics (NPV, IRR, payback period), interactive scenario testing, and a go/no-go recommendation. It's designed for founders and investors who need to validate viability before committing resources.
The ideal workflow uses both: SimpleFeasibility first to validate the concept, then ProAI (or similar) to plan the execution if the feasibility results are positive.

Where SimpleFeasibility Wins
Investment-Grade Financial Analysis
This is SimpleFeasibility's defining advantage. No other AI business analysis tool — ProAI included — automatically calculates Net Present Value, Internal Rate of Return, and payback period.
Why does this matter? Because NPV and IRR are the metrics that determine whether an investment creates or destroys value. A business plan with P&L projections can show strong revenue and profit, but without discounting future cash flows to present value, it fundamentally overstates the attractiveness of the investment. A project showing $500,000 in cumulative profit over 5 years looks great — until the NPV calculation reveals that the present value of those future cash flows, after accounting for the time value of money and risk, is actually negative.
Banks evaluating loan applications and investors evaluating equity opportunities expect to see NPV and IRR. A business plan without these metrics is incomplete for investment decision-making.
Interactive What-If Analysis
SimpleFeasibility's What-If analyser lets you adjust key assumptions in real-time using sliders and instantly see the impact on NPV, IRR, payback period, and break-even. Change the occupancy rate, adjust pricing, increase construction costs — the financial metrics update instantly.
This is transformative for decision-making. Instead of a single set of assumptions (which are always wrong to some degree), you can explore hundreds of scenarios in minutes. What's the minimum occupancy for a positive NPV? How much can construction costs overrun before IRR drops below your hurdle rate? What price point maximises the risk-adjusted return?
ProAI generates a single scenario. Testing alternatives requires generating a new plan.
Goal Seek Functionality
SimpleFeasibility's Goal Seek takes scenario analysis one step further. Instead of asking "what happens if occupancy is 65%?", you can ask "what occupancy do I need for a 15% IRR?" or "what price point gives me a 3-year payback?"
This reverse-engineering capability is unique among AI business analysis tools and directly mirrors the kind of analysis that professional consultants and investment analysts perform.
Speed and Simplicity
SimpleFeasibility generates a complete feasibility study in 2–8 minutes. ProAI takes 15–30 minutes. Both are dramatically faster than manual approaches, but when you're testing multiple concepts or locations, the difference compounds. Testing 5 different restaurant concepts takes 10–40 minutes with SimpleFeasibility versus 75–150 minutes with ProAI.
No Subscription Lock-In
SimpleFeasibility uses per-study pricing ($200–$2,000). You pay only when you need a study. ProAI uses annual subscriptions ($114–$409+), which means you're paying even in months when you don't generate any plans.
For occasional users — someone evaluating one or two business ideas — SimpleFeasibility's pay-per-use model is more economical. For users generating plans regularly, ProAI's subscription may offer better value per plan.
Where ProAI Wins
Business Plan Depth
ProAI excels at what it's designed for — comprehensive business plans. The output includes detailed operational plans, marketing strategies, management structures, and competitive positioning that SimpleFeasibility's feasibility-focused output doesn't cover in the same depth.
If you need a document to present to a bank that expects a traditional business plan format, ProAI delivers that format natively.
Pitch Deck Generation
ProAI can generate investor pitch decks directly from the business plan data. SimpleFeasibility doesn't currently offer pitch deck generation. For founders preparing for investor meetings, this is a genuine time-saver.
Investor Database
ProAI provides access to a database of 160,000+ investor contacts, which can be valuable for founders seeking funding. SimpleFeasibility focuses purely on the analysis and doesn't include investor matching.
Multi-Language Support
ProAI supports 9 languages, making it accessible to non-English-speaking markets. SimpleFeasibility currently operates in English only.
AI Business Advisor
ProAI includes an AI chatbot that answers follow-up questions about your business plan. This interactive guidance can be helpful for first-time founders navigating unfamiliar business concepts.
Pricing Comparison
| Scenario | SimpleFeasibility Cost | ProAI Cost |
|---|---|---|
| 1 study/plan per year | $200–$2,000 | $114–$409 |
| 3 studies/plans per year | $600–$6,000 | $114–$409 |
| 5 studies/plans per year | $1,000–$10,000 | $114–$409 |
| Quick validation only | $200 | $114 (annual minimum) |
| Full analysis + business plan | $2,000 | $409 |
ProAI's subscription model offers better per-plan economics for heavy users. SimpleFeasibility's per-study model is better for occasional users and avoids ongoing costs when you're not actively generating studies.
However, the pricing comparison is somewhat misleading because the outputs are fundamentally different. Comparing the cost of a feasibility study to the cost of a business plan is like comparing the cost of a soil test to the cost of an architectural blueprint — they serve different purposes in the same project lifecycle.
