Market position

Positioned in the language learning and language exchange app category alongside apps such as HelloTalk, Langotalk, Teuida, JustSpeak AI and TalkMe, differentiating on live group audio practice combined with an AI tutor. Company materials cite a community of about 1.5 million users.

Combines real-time group audio conversation with native speakers and a community of trainers with an AI speaking tutor and speech analytics (pronunciation heat maps, word and speaking-speed tracking, transcript-based insights), and allows listener-only participation for users not ready to speak. Korean-market focus extends into workplace translation and multilingual industrial safety training.

Technology

Reported web/app stack elements include Node.js, Express, Redux, jQuery, Bootstrap, PWA, Kakao, Amazon SES, Google Analytics, Hotjar, Google AdSense and Ghost.

Go-to-market

Distribution through the Apple App Store and Google Play plus a web app, with an open trainer-recruitment funnel (application, orientation, self-set schedule) for English, Korean, Japanese, Spanish and French teachers who are promoted via social media and an in-app discovery page and compensated with "bean" rewards. Enterprise sales are handled through a dedicated business site.

Individual language learners — particularly those studying Korean, English and Japanese, and users motivated by career advancement, travel or Korean pop culture — plus freelance language trainers who teach on the platform, and Korean manufacturing and construction employers with foreign E9-visa workforces and office teams preparing for TOEIC/OPIC.

Geography

Headquartered in Seoul, South Korea (Seongdong-gu, Seongsu-dong), with an international user base described as spanning more than 100 countries; trainer recruiting and Korean-language testimonials indicate a substantial Korean teacher community.

History

Founded in Seoul; the company describes itself as originally launched as a live audio platform for practicing spoken English and later evolving into an AI-driven language training solution, adding the Goguma AI tutor and a B2B offering for Korea's workforce. Its iOS app has been on the App Store since at least 2022 based on dated user reviews.

Risks & controversies

Recent Google Play reviews report app freezing, crashes, audio echo and a broken Facebook login that locked users out of accounts. An App Store review raised concerns about harassment in audio rooms and the adequacy of moderation and reporting tools.
