The checklist
How to choose an online course idea worth building
An idea is cheap until you start recording. Five checks before the build.
- Start where money already flows. According to Kajabi's August 2025 announcement, its creators have earned over $10 billion, led by health and fitness at $1.6 billion, with business and finance and personal development at $1.4 billion each. A proven category isn't a crowded category at the slice level: enter one with a specific audience and a specific result, and the demand is already warmed up.
- Count to 309, not to a million. The same Kajabi report profiles the average six-figure creator: 1,000 to 10,000 followers, an email list around 4,000, and 309 paying customers. The test for a niche idea isn't 'is this huge', it's 'can I name where those few hundred buyers already gather': a trade association, a subreddit, a local scene, a conference.
- Price the build in hours before you commit. The widely cited 2010 Chapman Alliance study of 249 organizations put one finished hour of basic e-learning at 79 production hours, and advanced interactive courses at up to 490. That's a corporate benchmark, a solo talking-head course runs far leaner, but the lesson transfers: production cost scales with format ambition, so choose the idea and the format together.
- Check the shelf life. According to IBM, a professional skill's half-life is about five years, and a technical skill's closer to two and a half. A course pinned to a tool's current interface starts decaying at launch; a durable-skill course amortizes its build for years. Tool courses can still win, just budget the re-recording into the price.
- Match the idea to its business model. Practice-shaped ideas suit memberships: Uscreen's fitness data has subscribers staying an average of 16 months at around $25 a month. Outcome-shaped ideas suit one-time courses or live cohorts, where the deadline does the finishing; altMBA reported 96% completion on its four-week format. Same idea, different model, very different business.
The two-year test
Two courses from the same creator, two years after launch.
Reading Financial Statements · launched 2024
Evergreen
The Complete PixelBoard 2024 Masterclass · launched 2024
Re-record due
Both courses took the same months to build. According to IBM, a professional skill's half-life is about five years and a technical skill's is closer to two and a half, so the version-locked course starts aging the day its subject ships a redesign, while the durable-skill course keeps selling as recorded. Tool courses can absolutely earn their keep, they just carry a maintenance bill: price the re-records in, or point the same effort at a subject that holds still.
Questions
Online course ideas, answered
Health and fitness leads Kajabi's platform at $1.6 billion in cumulative creator earnings, with business and finance and personal development at $1.4 billion each, per the company's August 2025 announcement. On Uscreen, fitness creators average $14,498 a month, which the platform reports as about 70% higher than its other industries, and faith is among its fastest-growing niches. Category profits don't transfer automatically, though: a specific slice with a reachable audience beats a broad entry into a rich category.
Fewer than most people guess. Kajabi's August 2025 report profiles its average six-figure creator with 1,000 to 10,000 followers, an email list of roughly 4,000, and 309 paying customers. The practical test for an idea is whether you can point at the room where a few hundred buyers already gather: a trade association, a subreddit, a local scene, a conference. If you can name the room, you can fill the course.
It depends almost entirely on format ambition. The widely cited 2010 Chapman Alliance study of 249 organizations found one finished hour of basic e-learning takes about 79 production hours, and advanced interactive content up to 490. That's corporate-grade production; a solo creator filming a talking-head course with slides runs far leaner. The takeaway is to pick the idea and the format together, and to pre-sell before you record so the build hours go to a proven idea.
Match the model to the idea's shape. Outcome-shaped ideas, launch the podcast, write the proposal, suit one-time courses or live cohorts with a deadline; altMBA reported a 96% completion rate on its four-week cohort format. Practice-shaped ideas, fitness, meditation, drawing reps, suit memberships: Uscreen's fitness data shows subscribers staying an average of 16 months at about $25 a month, which quietly outsells most one-time price tags.
The market says yes: Grand View Research projects the global e-learning services market will reach $842.64 billion by 2030, growing 19% annually, and Hotmart and Teachable reported 21 million consumers buying from their 200,000+ creators in a single year. The realistic caveat is distribution: a course sells because its audience is reachable and its promise is specific, so the idea and the room it sells to matter more than the market's size.
Yes. The generator runs in your browser, is free, and needs no signup. Enter your niche or skill and it returns course ideas shaped as sellable products: memberships, sprints, practices, and programs. Generate as many as you like, then judge each like a product: who pays, where they gather, and what it costs you to deliver and maintain.
