[This post updated in 2026.] Your business plan is the foundation of your business. It creates the roadmap, keeps you focused, and it’s what helps funders say yes to your funding requests. So, what goes into writing a business plan in the age of AI? Let’s go over what to include in a traditional business plan, why you need a one-page version, and how to leverage AI and professional editing to get your plan across the finish line.
In 2020, drafting a business plan meant hours of research, staring at a blank page, and hoping your financial projections were credible. In 2026, it’s possible to use large language models (LLMs) like ChatGPT, Claude, and Gemini to draft sections in minutes. For the purposes of this article, we’ll call them “AI” even though they’re not technically artificial intelligence.
These models are fast, but there’s a dual risk of hallucinations and sounding robotic. Your business plan is a reflection of your mission and goals. It should sound like you wrote it, not AI slop.
This article covers what to include in your business plan and how to combine LLMs and professional editing to get the best results.
Do Business Plans Still Matter?
In short: yes. Here’s why. There’s a temptation to think that in the age of AI-powered everything, the traditional business plan is obsolete. It isn’t.
Lenders still require them. Investors still read them. Partners and landlords still ask for them. And more importantly, forcing yourself to articulate your market, your competition, and your revenue model makes you a sharper founder.
The only thing that has changed is the threshold for getting started. AI has made it easy for anyone to throw in a prompt and come up with a “business plan.” A founder who procrastinated for months on a blank document can now have a working draft in an afternoon. That part is great. The question is whether that draft is any good.
That’s where the human work begins.
The Core Sections of a Business Plan
Your particular lender may ask for specific information, but here are the main sections lenders and investors expect to see. Knowing what a business plan contains is helpful, but you’ve still got to write it (or prompt it) yourself.
Executive Summary
An executive summary tells readers exactly what your business does, why it will succeed, and what you need from them in only two or three paragraphs.
The traditional approach: Most writers save this for last. It’s a summary of everything else in the plan, written once the rest is complete.
The AI-assisted approach: Still write it last, but use AI to synthesize your other sections into a tight, compelling overview. Feed in your completed sections and ask for a summary that leads with your strongest points. Then rewrite it in your own voice.
Business Description
The business description explains what your business will do, who you will serve, and who your competitors are. It describes your location and target audience. It’s the who, what, when, where, and why of your business. Paint a picture for potential investors, because this is where you sell them on the vision.
The traditional approach: Go into detail. Infuse it with your passion. The business description is where you make investors want to keep reading.
The AI-assisted approach: AI is good at structuring this section, but it can’t inject your passion or specific context without your help. Give the model real details on your origin story, your specific customer, your exact location, and it will organize them. But it will be generic. You still need to add your voice. Don’t be the founder just types “coffee shop in Austin” and accepts whatever comes back.
Legal Structure
What kind of business are you forming, and who’s involved? Lenders and partners want to know who’s running the show. Whether you use LLMs or not, you should still have a lawyer run through this section.
The traditional approach: List your key leadership team by role and name, including CEO, CFO, and any other principals. State your business structure: LLC, S-corp, limited partnership, sole proprietorship, and why you chose that as the best business structure.
The AI-assisted approach: This section is straight facts, so AI doesn’t really help with drafting. Where it does help is in explaining the implications of different structures. Ask it to compare an LLC versus an S-corp for your specific situation, then get your attorney’s input to catch hallucinations.
Market Analysis
The market analysis shows lenders how your business fits into the broader landscape, both locally and within the global industry. It demonstrates that you’ve done your homework and that you understand the opportunities and risks.
The traditional approach: Research your industry and local market manually by pulling reports, reading trade publications, and building a SWOT analysis from scratch. Yes, it’s time-consuming and usually the section founders dread most.
The AI-assisted approach: This is where AI can help. Ask an LLM to outline market trends in your industry, identify key competitors, and help you build a SWOT analysis. It’ll be much faster. That said, always verify everything independently. LLMs can hallucinate data, and a lender who catches fabricated stats will lose confidence in your entire plan.
Products or Services
The goal of this section is to make your benefit to customers undeniable. It’s the proof lenders and investors are looking for before cutting a check.
The traditional approach: Describe what you’re selling and how it solves a problem for your target customer. If you’re in R&D, describe your research roadmap as if it were your first product.
The AI-assisted approach: Use AI to sharpen your positioning language. Feed in your rough description and ask it to reframe your offering in terms of customer benefits rather than features. Then pressure-test it: ask the AI to argue against your product from a skeptical investor’s perspective. The objections it raises are ones you should be ready to address.
Marketing and Sales
This is where you describe the marketing strategies you’ll use to promote your product or service. If you’re creating something new, there may not be any proven sales yet. If that’s the case, treat the R&D phase like your initial service and explain everything you plan to do going forward.
The traditional approach: Outline how you’ll find customers and close deals. Select the marketing strategies best suited to your business and describe them in enough detail that an investor can see you’ve thought this through.
The AI-assisted approach: AI can help you identify marketing channels relevant to your industry and audience, draft a customer acquisition framework, and even outline a sales funnel. What it can’t tell you is whether your target customer actually spends time on Instagram or prefers direct mail. That insight comes from talking to real people. Use AI to build the structure, but use your market knowledge to make it specific.
Funding and Financial Projections
If you seek funding, this is where you ask. How much do you need to get your business running? Where will the money go: salaries, bills, equipment, or operating expenses? This is the section where you need an accountant or financial advisor alongside AI (if you use it here).
The traditional approach: State your funding ask clearly. Break down exactly where the money will go, with dollar amounts. Then project your financials over five years: income by quarter or month, cash flow, and capital expenditure. Accuracy matters more than optimism here. Beating a projection is great. Falling short could kill your business.
The AI-assisted approach: AI can help you build projection templates and model different scenarios, but it works best when you give it real numbers to work with. Don’t invent revenue figures. Give it your assumptions and ask it to structure them into a readable format. A lender or investor will probe your numbers, and you need to be able to defend every line.
Supporting Materials
The traditional approach: Attach anything that strengthens your case, including patents, founder resumes, product sketches, credit reports, letters of intent, etc.
The AI-assisted approach: AI won’t generate these for you, but it can help you write introductory paragraphs that contextualize each document and tells the reader why it matters.
Do You Still Need a Human?
There’s no question AI is useful for business plan writing. It removes the blank page problem, helps structure your thinking, and speeds up the drafting process. For founders who’ve been avoiding their business plan, it can be the push they needed to finish.
But AI-generated business plans have a recognizable sameness to them. They tend to be well-organized and hollow. We can all spot the robotic “it’s not this, it’s that” structure of LLM-generated copy. A ChatGPT business plan might have the right structure, but it has none of the specific detail that makes a funder believe in your business.
When you leave it all to AI, your market analysis cites vague trends. The executive summary sounds like a template. The financial projections lack real assumptions behind them.
How to fight that? Specificity. Give the model detailed, accurate inputs about your actual business. The more context you provide, the better the output. Once you generate a draft, a human editor brings in the voice and nuance to turn a competent plan into a compelling one.
What About a One-Page Business Plan?
Not every business plan needs to be 30 pages. For early-stage founders, solopreneurs, and entrepreneurs pitching an early conversation (not a formal funding round), a one-page business plan is usually enough.
A one-pager distills your concept, market, model, and ask into a single, scannable document. It won’t replace a full plan when you’re applying for an SBA loan, but it’s a way to get early interest and feedback.
If you’ve already put in the work for a full business plan, AI is good at creating a simple one-page version. Just upload your plan and ask it to synthesize a one-page version. (Note: check your privacy settings to make sure the LLM won’t use your document in its future training.)
