Hello AI Key Features

Hello AI is not just a simple chatbot, it’s an innovative platform where anyone can easily create and utilize "realistic" AI humans with unique appearances and personalities, capable of responding instantly and expressing emotions.

AI Human Generation

Enter an image or keyword and get a high-resolution digital human within a minute. Anyone can create their own AI character with just a few clicks.

🔍 Generative technology is applied to automatically combine various faces and normalize physical features, quickly generating natural faces without improvisation.

Real-time Conversation

The AI responds instantly to user questions with lifelike lip-sync and voice, delivering natural and immersive conversations that feel just like talking to a real person.

🔍 AI voice and facial animations are synthesized in real time based on user input, with expressive facial changes planned during conversation.

Document Learning Chatbot

Upload PDFs or web links, and the AI learns the content to become a domain-specific chatbot. It acts as an automated knowledge assistant enriched with expert insights.

🔍 Documents are split and semantically classified. The AI searches and responds with relevant content in real time based on questions.

Multi-channel Integration

Generated AIs can be integrated across platforms like websites, mobile apps, and kiosks, making them ideal for business expansion.

🔍 AI characters are provided as web/app SDKs or video APIs, allowing for easy embedding into various interfaces.

Korean Optimization

Delivers authentic localization with voices and expressions reflecting Korean intonation, grammar, and emotional nuance.

🔍 It features natural intonation based on Korean voice data, along with voice speed and tone adjustment algorithms for expressive emotion delivery.

Fast Response Speed

Responds within 2.4 seconds on average, and within 1.5 seconds when cached — leading the industry in real-time interaction.
