You have expertise. You have an audience — or at least an idea of one. What you don't have is clarity on what course to build. That's where most people get stuck, and it's where ChatGPT is useful — not as an idea generator that hands you a finished concept, but as a brainstorming partner that helps you think through possibilities faster than you could alone. The trick is knowing how to prompt it past the obvious suggestions.

Why ChatGPT works for brainstorming (and where it doesn't)
ChatGPT is good at generating lots of ideas quickly, combining concepts in unexpected ways, and pushing past your initial assumptions. It's less good at knowing which ideas are actually viable — it doesn't know your market, your audience's real pain points, or what you're uniquely qualified to teach. That's why brainstorming with ChatGPT works best as a structured conversation across multiple rounds, not a single "give me course ideas" prompt.
I've noticed that course creators who brainstorm with AI tend to either accept the first suggestions uncritically or dismiss them all as too generic. Both miss the point. The value is in using ChatGPT's suggestions as starting material that you then shape with your own knowledge of your audience.
Round 1: Divergent exploration
The first round is about quantity, not quality. You want at least 15-20 ideas on the table before you start evaluating. Give ChatGPT rich context about your background, then ask it to think broadly.
Start by sharing three things: your area of expertise (be specific), your target audience (who you naturally attract or want to serve), and any constraints (format preferences, time availability, price range). Then ask for ideas across different formats — workshops, self-paced courses, cohort programs, micro-courses — because the right format often changes the viability of an idea entirely.
The first 5-7 suggestions will be predictable. That's fine. Push past them by asking ChatGPT to explore adjacent problems your audience faces, unconventional formats, or combinations of your skills that don't seem obviously course-worthy.
Round 2: Critical filtering
Now ask ChatGPT to turn critical. Take your list of 15-20 ideas and ask it to evaluate each one against three criteria: Is there an existing audience actively looking for this? Does the creator (you) have a unique angle that competitors don't? Can the transformation be delivered in the proposed format?
This is where the conversation gets interesting. ChatGPT will often identify weaknesses you hadn't considered — an idea that sounds great but has no natural search audience, or one that requires 6 months of content when your timeline is 6 weeks. It'll also occasionally flag strengths you overlooked — a niche intersection where you have unusual credibility.
Be honest with yourself during this round. If an idea excites you but ChatGPT raises legitimate concerns about market demand, don't dismiss the feedback. Investigate it. Excitement about a topic doesn't guarantee anyone will pay to learn about it.
Round 3: Validation framing
For your top 3 ideas, ask ChatGPT to help you define what validation would look like. What would you need to see before investing weeks of work building the course? This might be: 50 people on a waitlist, 5 beta students who complete a pilot, or evidence that people are already paying for inferior versions of what you'd create.
This round shifts from brainstorming to planning. You're not asking ChatGPT whether the idea is good — you're asking it to help you design a test that would answer that question with real-world data.
Prompts to try
I'm a [your profession] with [X years] of experience specializing in [your niche]. My ideal students are [specific audience]. Generate 15 course ideas that range from obvious to unexpected. For each idea, include: the course title, who it's for, the specific transformation it delivers, and whether it's best as a self-paced course, live cohort, or workshop. After listing all 15, flag which 3 you think are most viable and why.
The instruction to range from "obvious to unexpected" pushes ChatGPT past its default of safe, predictable suggestions. The viability assessment at the end forces a second pass that catches weak ideas early.
Here are my top 5 course ideas: [list them]. Play devil's advocate. For each one, give me: the strongest argument against building this course, the most likely reason it would fail, and one thing I could change about it to make it more viable. Be direct — I'd rather hear hard truths now than invest months in the wrong idea.
The explicit permission to be critical is important. Without it, ChatGPT defaults to encouraging every idea equally, which isn't useful. The "one change to make it more viable" instruction ensures you get actionable feedback, not just criticism.
I'm leaning toward building a course on [your top idea]. Before I commit, help me design a validation experiment. What's the smallest version of this course I could offer to test demand? Who should I offer it to? What response rate would indicate real interest versus politeness? What would I need to see from a pilot group of 5-10 students to know this idea is worth scaling?
This prompt bridges brainstorming and action. The best course idea in the world is worthless without validation, and ChatGPT can help you think through a lean test.
The human layer
ChatGPT doesn't know what keeps your clients up at night. It doesn't know the question you get asked in every workshop that made you think "someone should teach this properly." It doesn't know the gap between what's available in your field and what practitioners actually need.
The ideas that become successful courses almost always start from something you've observed directly — a pattern in your client work, a skill gap in your industry, a problem you solved for yourself that others still struggle with. ChatGPT helps you articulate and refine those observations. It doesn't replace them.
Use the brainstorming to surface ideas, but validate them against your own experience. The course idea that makes you think "I could talk about this for hours and never run out of material" is usually the right one — as long as someone's willing to pay for it.
What it gets wrong
It defaults to broad, safe topics.
"How to Start a Meditation Practice" is a fine course idea if you want to compete with 10,000 other courses. ChatGPT gravitates toward these because they're well-represented in its training data. Push for specificity: "Meditation for Emergency Room Nurses" has a clearer audience and less competition.
It overestimates demand for niche topics.
ChatGPT will enthusiastically tell you there's an audience for almost anything. It can't tell you whether that audience is 50 people or 50,000, or whether they'd pay $47 or $497. You need market research for that — try Perplexity for demand validation.
It can't evaluate your competitive advantage.
ChatGPT doesn't know what makes you different from every other expert in your field. The best course ideas leverage something specific about your experience, perspective, or methodology that competitors can't replicate. You have to bring that insight yourself.

Brainstorming with ChatGPT won't give you a perfect course idea. It'll give you a richer set of possibilities than you'd generate alone, filtered through structured critique, with a clear path to validation. That's the real value — not the ideas themselves, but the process of thinking through them more rigorously.
