Progrit Launches AI-Driven Speaking Improvement App "Supiful" in South Korea

In a significant move for English education, Progrit Inc., based in Tokyo, Japan, is set to launch its specialized subscription-based English learning service, "Supiful" (known as "스피플" in Korea), on September 8, 2025. This groundbreaking platform focuses on enhancing speaking skills through personalized AI-driven learning experiences. Over the past year, Progrit's services have seen remarkable growth, illustrated by a 4.2 times increase in paid memberships, indicating a robust demand for efficient language learning solutions.

Understanding the Korean Market

The expansion into South Korea is strategically timed. The country boasts a high export ratio in essential industries such as automotive and semiconductors. According to the World Bank, South Korea’s export-to-GDP ratio is projected to reach 44% in 2023. Such a global market integration has increased the emphasis on English speaking skills in professional environments, where assessments like OPIc (Oral Proficiency Interview-computer) are becoming commonplace in hiring and promotion evaluations.

Moreover, Korea ranks 50th out of 116 countries in the English Proficiency Index (EF EPI 2024), signaling a strong foundational knowledge but highlighting a need for improved business communication capabilities. This presents a ripe opportunity for Progrit to introduce its successful model from Japan into a similarly structured educational landscape, where high educational standards and a focus on exam-oriented learning prevail.

What is "Supiful"?

"Supiful" is an innovative subscription service that incorporates two primary types of training effective for practicing English speaking: 1) Oral English Composition, which engages users in instant translation of Korean to English, and 2) Solitary English Conversation, where users express their thoughts on selected themes as if speaking to themselves in English. Each session lasts 30 minutes, with real-time feedback from AI to foster continuous improvement in speaking abilities. Since its launch in December 2023, "Supiful" has garnered positive reviews for its effective learning experience, leading to its impressive membership growth.

Features of Supiful

- Oral English Composition: This exercise allows users to practice translating Korean phrases instantly into English. AI evaluates the nuances of responses, providing immediate corrections based on context rather than strict comparisons. Users can access real-time clarifications from AI anytime, enhancing the learning experience.

- Solitary English Conversation: Participants select a topic and articulate their views in English as if having a monologue. AI assesses not only the grammatical and expressional correctness but also content quality and structure, guiding users towards greater fluency and confidence.
