CAS English（캐스영어）is an online English conversation service operated by Korea-based Sevenhour. Its core selling point is one-on-one lessons with “100% American/Canadian native North American speakers.” Classes are conducted via Zoom, with video or audio options available. The service emphasizes building a long-term English output environment through a fixed teacher and fixed schedule.
Courses cover adult free conversation, news discussions, debate, beginner/intermediate/advanced English, business English, travel English, picture description, OPIC, TOEIC Speaking, IELTS, as well as leveled reading and conversation for children. The website showcases a large amount of self-developed teaching material, ranging from news and social issues to science and culture topics for children, with frequent updates. In terms of teachers, the platform stresses that it does not use Filipino teachers, nor does it hire international students or overseas Korean instructors. It also states that teachers go through a four-stage recruitment process, and that it can help match or change teachers later based on student feedback.
Pricing is based on 25-minute or 50-minute lessons, taken 2, 3, or 5 times per week. Monthly fees for 25-minute lessons range from KRW 140,000 to KRW 320,000, while monthly fees for 50-minute lessons range from KRW 264,000 to KRW 620,000. A 5% discount is available for three-month payments. The trial is not free: users must first sign up for a regular course, and if they are not satisfied with the first lesson, they can receive a refund after deducting KRW 10,000 for a 25-minute lesson or KRW 20,000 for a 50-minute lesson. Payment supports card payments and bank transfers, and users can request cash receipts, tax invoices, and similar documents.
The advantages are its clear positioning, the relative scarcity of North American foreign teachers, and fixed scheduling that helps with consistency. The teaching materials are diverse, covering adults, children, exams, and business scenarios. Pricing is also relatively competitive for one-on-one classes with North American teachers. The limitations are that the service is clearly aimed at Korean users: the website, customer support, Kakao consultations, and payment environment are all centered on Korean language and local Korean systems. Available class times are mainly concentrated between 6 a.m. and 11 a.m., and 8 p.m. and midnight Korea time. No authoritative certificates or course accreditation information was found. The CasGPT AI assistant is a plus, but it is still a free beta and does not guarantee accuracy.
It is better suited to learners in Korea or those familiar with a Korean-language environment who want stable, long-term speaking practice, especially those who value a North American accent and an ongoing relationship with a fixed teacher. The text does not specify accessibility from mainland China. Zoom, Korean payment methods, and Kakao-based consultation may create practical barriers, so it is advisable to confirm network access, payment availability, and customer support usability in advance.
