Tokyo, Japan - 3 August 2025 - Teenage Business Contest Japan (TBCJ) has named Tokyo Techies its exclusive technology partner for the 2025 competition, to be held on 7 August at The EGG in the Shin-Marunouchi Building. Central to the partnership is TB-Chan, a custom AI assistant powered by Tokyo Techies’ flagship platform Kotae AI.
TB-Chan already answers hundreds of questions from students, judges, sponsors, and media - covering everything from contest rules and scoring rubrics to data sources such as RESAS, RAIDA, and JETRO - while continuously improving as new content is added.
Why Kotae AI Stands Out
Kotae AI was engineered over months of R&D to solve problems hobby chatbots cannot:
- Accurate intent detection & smart routing - Each question is semantically analysed, then routed to the right knowledge base or "scope” automatically. The same engine can even replace terms on the fly (for example, mapping "hotel” to "stadium” in an enterprise roll-out).
- Built-in guardrails - Out-of-scope queries, low-confidence matches, or inappropriate requests are stopped before they reach the user, preventing hallucinations and keeping confidential data safe.
- Battle-tested Retrieval-Augmented Generation (RAG) - Kotae AI uses the optimal vector database and large-language model for each project, and supports rapid re-training so answers stay fresh.
- Enterprise-grade performance - Techniques such as asynchronous retrieval, aggressive caching, and model quantisation keep responses snappy while controlling API spend.
- Low-code, 10-minute deployment - Non-technical users upload documents or a website URL, choose a design, and drop a script onto their site. Voice, decision-tree flows, and CRM integrations are available for larger roll-outs.
"Everyone thinks an AI chatbot is a weekend project until traffic spikes or the first tough question arrives :-) ” said Duc Doba, Founder and CEO of Tokyo Techies. "We built Kotae AI so schools, SMEs, and large enterprises can launch fast and trust the answers at scale. TBCJ shows how a lean team can support nationwide innovation - without drowning in emails.”
Real-Time Impact at TBCJ
After announcing the contest, TBCJ founder Millie Gan was inundated with inquiries: "I signed up for Kotae AI with zero coding background and had TB-Chan live in less than ten minutes. Now we train it daily - even with concepts like Nobel Prize-winning Nudge Theory - so students get instant, reliable guidance,” she said.
By off-loading repetitive questions to Kotae AI, the volunteer-run contest can focus on mentoring students and securing new sponsors, illustrating how AI lowers operational costs while raising service quality.
