ONEBOT – Next-Generation AI Chatbot System with RAG Architecture

Project Context

Small and medium-sized enterprises (SMEs) in Japan are facing a severe labor shortage crisis. Customer demand for instant 24/7 responses is increasing, while the cost of maintaining overnight support teams is extremely high.

Challenges

Customer Loss

53% of customers abandon the service if they have to wait more than 10 minutes.

Operational Costs

Recruitment and training costs for customer service staff continue to rise.

Technical Barriers

Existing AI solutions are often too complex to implement or may generate inaccurate responses.

VAON's Solution

Private Data Training: The AI responds only based on the company's internal documents (PDFs, websites, Excel files), ensuring high accuracy.

Hybrid Model: Flexibly combines button-based scripted flows (for fixed processes) with generative AI (for complex questions).

Omnichannel: Deep integration with LINE Official Account (the most popular communication channel in Japan) and websites.
