Company Overview#
KL Cube is a South Korean AI company that develops digital-accessibility services for Deaf and hard-of-hearing users. Its main platform, HandSignVerse, converts Korean text or speech into Korean Sign Language (KSL) and presents it through 3D avatars.
The service works across websites, mobile apps, kiosks, digital desks, QR-linked pages, and video content. KL Cube also develops AI contact-center software, while its current growth strategy focuses on sign-language and accessibility services.
Technology & Product#
HandSignVerse combines Korean-language analysis, sign-language sentence generation, sign-asset retrieval, avatar animation, and content management. Its NOVA engine analyzes text or speech, creates a sign-language sequence with facial and body expressions, selects matching assets, and renders a 3D avatar.
The platform also includes HandSign TalkTalk for information and consultation, QRing for QR-based guidance, SignBot for rule-based conversations, and MindSign for signed meditation and emotional-care content. Organizations can use the platform as on-premise software, SaaS, or a hybrid deployment and connect it to existing services through APIs.
KL Cube has built a Korean-KSL parallel corpus of more than four million eojeol across public administration, healthcare, finance, education, tourism, shopping, news, and daily-life domains. Specialist reviewers check translations before release.
Market & Use Cases#
KL Cube serves public agencies, hospitals, banks, insurers, transport operators, tourism organizations, libraries, schools, and consumer-service companies. These organizations can add sign-language guidance without building their own translation, avatar, and review workflow.
Typical uses include accessible ticketing and information kiosks, mobile banking guidance, hospital navigation, signed food information linked by QR codes, museum and tourism content, digital sign-language books, and guidance on smart devices.

Collaboration Relevance#
Banks, hospitals, public agencies, transport operators, and tourism businesses can add HandSignVerse to an existing app, website, kiosk, or customer desk. A focused PoC can test translation quality, user comprehension, response time, and operational workload for one service journey.
Device makers can license the platform for kiosks, vehicles, appliances, tablets, and digital desks. For Korea-Europe expansion, KL Cube can work with local sign-language experts, accessibility organizations, and distribution partners to build country-specific language assets and meet local accessibility requirements.
