What It Is

Lessi is a beta web service operated by Korea-based LeoWorks. It is positioned as a booking, payment, class-pass, and notification platform for “one-person lesson pros.” Its goal is to let individual instructors in areas such as Pilates, golf, yoga, and personal training complete the full flow from booking to payment through a single link in their Instagram bio.

Core Capabilities

Based on the main content, Lessi’s core modules include online payments, class passes, and automated notifications. Students can pay directly through an instructor’s link, with planned support for bank cards, KakaoPay, and NaverPay. Prepaid packages such as 10-class or 20-class passes can be automatically deducted when a booking is made, reducing disputes over remaining sessions. The system automatically sends payment-completed messages, booking confirmations, and Kakao 알림톡 reminders 24 hours before class. The platform also supports instructors creating lesson products, and allows offline payments such as cash, card-terminal payments, and bank transfers to be manually recorded in the system.

Pricing and Plans

Lessi offers a free plan, allowing instructors to start using it at no cost. When online payments occur, a 1.5% application fee is charged. There is also a Pro monthly subscription that removes the application fee, but the exact monthly price should be confirmed on the payment page. Online payments also incur PG payment gateway fees, which are deducted from the instructor’s settlement amount. It is worth noting that the top of the page clearly states that the payment feature is still being prepared and will be available soon.

Integrations, Security, and Deployment

Registration supports Kakao, Naver, Google OAuth, and email verification. For payments, the site mentions that Toss Payments stores the card billing key, while the company only stores the necessary identifiers. Notifications rely on Kakao 알림톡. The deployment model appears to be the lessi.co.kr cloud web service, with no self-hosting option observed. The main content does not disclose information about APIs, developer documentation, team collaboration, role-based permissions, audit logs, or compliance certifications.

Pros, Cons, and Best Fit

The main advantage is that Lessi is highly focused on a specific use case, addressing the most common needs of individual instructors: booking, class-pass deductions, reminders, and payment collection. The free plan also lowers the barrier to early adoption. The drawbacks are that it is still in beta, payment capabilities are not yet fully launched, Pro pricing is not transparent, and enterprise-level collaboration, permissions, and open integration capabilities are missing. It is best suited to Korea-based individual instructors or small studios that rely on Instagram for customer acquisition and operate with class-pass packages.

Access from China and Alternatives

The main content does not provide information about access from mainland China. In addition, capabilities such as KakaoPay, NaverPay, and Kakao notifications are clearly oriented toward the Korean local ecosystem, which may not fit Chinese instructors’ needs in terms of network access, payment collection, notification delivery, and local tax workflows. For students in China, alternatives may include 小鹅通, 有赞教育, and WeChat mini program class-booking tools. International alternatives include Calendly, Acuity Scheduling, SimplyBook.me, Mindbody, and others.
