TL;DR: These platforms aren't competing for the same thing. Teachable is for selling courses. Kajabi is for running an all-in-one creator business. Skool is for building a community. Picking the wrong one costs you time and money.
I've used all three. The comparison articles you find online usually miss the most important distinction.
They're not different versions of the same thing. They're built around completely different outcomes.
What each platform is actually designed for
Teachable is a course platform. Clean interface for video lessons, quizzes, and certificates. Community features are minimal by design. It's built for creators who want to sell structured, self-paced content and get out of the way.
Kajabi is all-in-one. Courses, community, email marketing, website, and sales funnels under one roof. The most expensive option. It does many things competently but few things exceptionally. You pay for the convenience of not managing multiple tools.
Skool is community-first. The core product is a private group with a feed, a classroom section for structured content, a calendar for events, and a gamification layer. Courses exist inside Skool, but they're secondary to the community experience.
One rule that's served me well: if your product is a course that people go through once and leave, use Teachable. If you want to build a recurring membership with real relationships, use Skool.
The pricing difference that actually matters
Teachable and Kajabi charge based on your revenue or member count as you scale. Skool charges creators a flat $99 per month, regardless of how many members they have.
On Kajabi at $399 per month, a creator needs significant revenue just to break even on the platform cost. On Skool at $99 per month, a creator with 10 members paying $20 per month is already profitable. That changes who can build sustainable communities and at what stage.
For members, Skool community prices are set entirely by the creator. Looking at the 1,000+ communities tracked in the KoolReviews directory, 693 are completely free and 307 are paid. Paid community prices range from $9 per month up to several thousand dollars per month, depending on the level of coaching access included.
What Skool's scale actually looks like
The numbers from the KoolReviews directory put Skool's growth in context.
The largest community on the platform, AI Automation Agency Hub, has 294,700 members and is free to join. AI Automation Society has 259,700 members. These aren't niche groups anymore. Communities at this scale would have been considered large online courses a few years ago.
Even mid-tier free communities are substantial. Mobility & Injury Prevention has 175,400 members in the Health category. The Virtual Bookkeeping Series has 77,000 members teaching a specific professional skill.
That scale is possible partly because of the $99 flat fee for creators. There's no platform tax that scales with your success.
What real members say about Skool communities
After indexing member reviews across the platform, a few patterns show up consistently.
What members value most:
- Direct access to the creator or their team
- Regular live calls or events that keep the community active
- A structured classroom section with real content, not just a feed
What members complain about:
- Communities that lose momentum after the initial launch period
- Creators who are less active than the price suggests they should be
- Paid communities that feel too similar to the creator's free content
Skool's community design amplifies outcomes in both directions. When a creator is engaged, the feed and gamification keep members coming back daily. When a creator goes quiet, the community feels like a ghost town faster than it would on a course platform because the whole product is the live interaction.

Category breakdown: where creators are building
The 1,000+ communities in the KoolReviews directory break down across nine categories:
- Money: 380 communities, the largest category on the platform
- Self-improvement: 190 communities
- Tech: 106 communities, but the highest average member counts
- Health: 92 communities
- Hobbies: 92 communities
- Spirituality: 60 communities
- Relationships: 33 communities
- Music: 25 communities
- Sports: 22 communities
Tech has the highest average member count because of the AI wave. Money has the most communities because the niche is competitive and easier to monetize. If you're evaluating where to build, these are the markets with the most existing demand.
When Skool is the right choice
Skool makes sense if you want to build a recurring membership business rather than sell one-off courses, if your audience values peer interaction as much as creator content, and if you want to keep overhead low at $99 per month flat.
When Teachable or Kajabi make more sense
Teachable makes more sense if you primarily sell self-paced courses where students aren't looking for community. It's the simpler, lower-risk option when you're starting out.
Kajabi makes more sense if you need email marketing, landing pages, and course delivery in one place and have the revenue to justify the higher monthly cost.
The platform is infrastructure
The platform matters less than the creator and the community.
A great creator on Teachable beats a mediocre creator on Skool. The platform is infrastructure. The creator and the other members are the product.
If you're evaluating a specific Skool community, start with member reviews on KoolReviews, check the creator's outside content and engagement history, and use the compare tool to see how it stacks up against alternatives in the same niche.
Browse by category: Money, Tech, Health, Self-improvement, or all nine categories.
