Circleとは何ですか?
Circle.so is an online community platform for creators, brands, and online 仕事 所有者。
It uses Spaces and Space Groups to organize discussions, courses, and events.
Each community platform space can be public, private, or secret.
That structure gives community builders real control over who sees what.
Many teams move here after outgrowing a Facebook group.

💡 Name check: This review covers Circle.so, the community software. It is not Circle Internet Financial (the USDC company), the Circle parental-control app, or the Netflix show.
Here is a walkthrough of the Circle platform in action.

丸
Built for discussion-first communities. Spaces, chat, and native live streaming sit in one clean dashboard.

|---|---|---|
| プロ | 月額89ドル | Solo creators launching a first community |

📌 注記: The Professional plan caps admins, moderators, and spaces. The Business plan raises those limits and unlocks a custom domain and priority support.
⚠️ Pricing conflict flagged: Our CSV lists the Enterprise entry as features rather than a figure. Outside research puts Enterprise at $399/month. Check the pricing Circle publishes before you buy.
Circleの主なメリット
Circleを検討する価値がある理由は以下のとおりです。

- Paid memberships: Charge for access through Stripe in multiple currencies. Discounts and coupon codes are built into checkout.
- 自動化ツール: Workflows handle repetitive community management jobs. They also personalise the welcome message new members receive.

機能比較
Circle and Kajabi overlap more than they used to. The table below shows where the two products still split apart.

| 取引手数料 | 0.5%~4% | なし |
| 最適な用途 | コミュニティづくり | オンラインコースの販売 |
1. Community Spaces and Group Discussions
丸: Spaces and Space Groups organise the entire community around themes. You can run multiple spaces, lock private spaces behind a plan, and open chat spaces for threaded group discussions. Members switch between communities with one click.

カジャビ: The community feature covers posts, events, and challenges. It works, but it sits beside the course product rather than driving it. Community management here is lighter than what a dedicated community platform offers.
2. Live Streaming and Live Events
丸: Native live streaming runs inside the platform. Circle handles small group sessions for up to 30 people and a ライブストリーム for up to 100 viewers. You can host events and send reminders without leaving the dashboard.

カジャビ: There is no equivalent live streaming feature. Creators usually run sessions on Zoom and post replays or ユーチューブ videos inside a course module.
⚠️ 警告: Circle’s live tool lacks the moderation controls of dedicated ウェビナー software. Large paid events may still need a separate host.
3. Course Builder and Course Functionality
カジャビ: The Kajabi course builder needs no code. Templates, quizzes, and progress tracking come standard, and students find courses through a clean member portal. Course creation is the strongest part of the product.

丸: The course builder supports videos, audio, and PDFs. It works for a lightweight cohort, but it trails Teachable and Kajabi on grading, drip logic, and reporting.
4. Digital Products and Coaching Programs
カジャビ: One Kajabi account can sell downloads, a membership site, podcasts, and coaching programs. A course creator running a coaching business can keep every product on the same platform.

Coaching gets its own workspace rather than a generic product type.

丸: You sell access, not products. Paid memberships unlock certain spaces, and free trials let people look around first. Anything more complex needs a third-party checkout.
5. メールマーケティングとキャンペーン
カジャビ: Broadcasts, sequences, and marketing campaigns all live here. Most creators drop their outside email marketing software once marketing efforts move in.

Artificial intelligence also drafts newsletter copy from your existing content.

丸: Email covers community-driven sends such as invitations and digests. It reaches other members well, but it is not a replacement for a full campaign tool.

6. Website Builder and Landing Pages
カジャビ: An intuitive website builder handles your entire website, blog posts, and unlimited pages. You can create landing pages from templates, and Kajabi websites publish on a custom domain.

丸: The website builder is newer and simpler. It covers a landing page and a member-facing home, not a marketing site with funnels.

7. Automation Tools and Workflows
丸: Workflows automate repetitive jobs and personalise onboarding for new members. Automated check-ins nudge quiet people back into the conversation.

Check-ins run on their own schedule once you set the trigger.

カジャビ: Automations attach to sales funnels, so a purchase can trigger emails, tags, and access changes. The branching is deeper than Circle’s, which stays inside the community.

⚠️ 警告: Circle’s automation is often described as basic. Complex multi-step logic usually needs ザピエール or a similar bridge.
8. Analytics and Member Activity Tracking
丸: Activity tracking shows who posts, who lurks, and where community engagement drops. That helps you spot the members worth promoting to moderator.

カジャビ: Reporting leans commercial. You get revenue, conversion rates, subscription metrics, and course progress in one dashboard.

9. Customization, Gamification and Extra Channels
丸: Brand colours, logos, and layout are all editable. Gamification adds points and leaderboards, a cool feature for keeping quiet members active.

Points and ranks sit on member profiles where everyone can see them.

カジャビ: Design control is tighter, which some creators find limiting. In exchange you get channels Circle does not have, including ポッドキャスト hosting through Creator Studio.

10. 価格設定とコスト
プランを並べて比較してみましょう。
| プラン | 丸 | カジャビ |
|---|---|---|
| エントリ | Professional: $89/month | Kickstarter: $71/month |
| 中 | Business: $199/month | Basic: $199/month |
| Upper mid | — | Growth: $159/month |
| トップ | Enterprise: Rich members’ profile, events | Pro: $319/month |
| アドオン | Plus Branded App: Custom Pricing | — |
| Sales cut | 0.5%–4% transaction fee | No transaction fees |
丸: The sticker price is only part of pricing Circle correctly. A transaction fee of 0.5% to 4% stacks on Stripe’s 2.9% + $0.30, so cost rises as revenue does.
カジャビ: Entry pricing undercuts Circle by $18 per month, and no cut is taken from sales. Replacing separate marketing tools can beat the $600 monthly stack many creators run.
💡 プロのヒント: Do the maths at your own revenue. At $10,000 in monthly sales, a 4% fee costs $400 before card processing.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| To sell courses first | カジャビ | Deeper course builder |
| Discussion-led community | 丸 | Spaces and threaded chat |
| Zero cut on sales | カジャビ | No transaction fees |
| Native live streaming | 丸 | Streams built into the platform |
| 何でもできる万能ツール | カジャビ | Site, email, and checkout included |
| 最低価格 | カジャビ | $71/month versus $89/month |
💰 あなたの予算
Kajabi’s Kickstarter tier is the cheapest way in. Circle looks close on paper until the transaction fee lands on every sale.
🔌 あなたの技術スタック
Kajabi replaces more of your stack, including email and checkout. Circle assumes you keep some tools and connect them, though integrations are thinner than on other platforms.
📝 あなたのコンテンツスタイル
Daily conversation and live events point to Circle. Structured lessons that create online courses point to Kajabi.
🎓 あなたの経験レベル
Circle’s interface reads easily if you already Slackを使用する or Notion. Kajabi has more screens, but Kajabi University walks new users through the core features.
🆓 無料トライアルとデモ
Both offer a trial, and Circle’s runs 14 days on every tier. Import real content instead of dummy 文章 so the test means something.
🛟 サポートオプション
Kajabi runs 24/7 help on the Growth and Pro plans, while the Basic plan drops live chat. Circle keeps priority support for the Business plan and above.

私たちのレビューで取り上げられなかったこと
This comparison focused on solo creators and small teams. We did not test bulk licensing, single sign-on, or how either tool handles a community with unlimited members on an Enterprise plan. We also did not benchmark support channels under load. If you run a large operation, your priorities will differ from what we covered here.

🏆 WINNER: KAJABI
Kajabi wins 4 of 7 categories.
最適な用途: course creators, coaching programs, memberships, and anyone who wants to grow your business on one bill.
Circle and Kajabi are not really the same product. Circle sells a thriving online community. Kajabi sells the machinery of a successful online business.
Circle is the better home for daily conversation, live streams, and member-led momentum. Tens of thousands of creators use Kajabi because it removes the sales cut and folds marketing into the same bill.
If your revenue comes from courses and digital products, Kajabi is the safer pick. If the community itself is the product, Circle earns its price.
