OneBot AI Chatbot Released for Agency Partners in Japan and Vietnam

VAON Viet Nam today announced the release of OneBot, an AI chatbot platform built specifically for agency partners serving the Japanese and Vietnamese markets.
 

OneBot is designed to help agencies — marketing agencies, IT consultancies, and system integrators — add AI chatbot offerings to their service portfolio without taking on the AI engineering and infrastructure burden themselves.

・What makes OneBot different

OneBot stands out from generic chatbot platforms in three key areas:

1) RAG-grounded accuracy. OneBot ingests client documents (PDFs, manuals, FAQs, websites) and grounds every AI response in those sources. This eliminates hallucination and produces answers that speak with authority on each client's specific domain.

2) Native LINE integration. With over 95 million LINE users in Japan, OneBot connects to existing LINE Official Accounts in minutes — not weeks of custom development.

3) Full white-label OEM. Agencies can sell OneBot under their own brand: custom logos, brand colors, custom domains, and agency-branded admin panels.
 

The platform runs on AWS Tokyo region for data sovereignty and supports BYOK (Bring Your Own Key) for Gemini API, giving agencies and their clients full control over LLM costs and data routing. The handoff feature, included by default, allows seamless transition from AI conversation to a human operator when needed.
