About PlusOne
PlusOne develops artificial intelligence and immersive technology for English-language learning and communication training. Founded in August 2016, the company combines conversational AI with mixed reality and virtual reality to help learners practise interactions relevant to work and education. Its products serve corporate training programmes, academic institutions and individual learners.
Immersive conversation practice
Smart Tutor places learners in simulated workplace situations, including executive meetings, sales negotiations and formal presentations. The platform launched for business clients in 2018 and reached consumer markets in 2020. Its proprietary HoloSapiens hologram engine provides conversational AI avatars for interactive practice.
The system evaluates both spoken communication and non-verbal behaviour. Its analytics cover vocabulary, grammar, pronunciation, speaking rhythm, fluency, eye contact and physical presence. Learners receive quantitative scorecards intended to identify areas for improvement and support focused practice. Emotion and biometric tracking form part of the company's broader approach to understanding human interaction within immersive environments.
Mobile learning and delivery
Smart Tutor LITE and TalkGrammar extend conversational training to smartphones. These applications integrate OpenAI GPT conversational models and use news articles from Nikkei LissN as material for discussion. This gives learners an additional way to practise spoken English beyond dedicated VR equipment.
PlusOne combines software subscriptions with practical support for training delivery. Its offering includes VR headset lending, custom curriculum development and progress coaching for enterprise and academic clients. Supported hardware includes Meta Quest devices.
The company operates from the United States and serves the Japanese market through a dedicated subsidiary established in 2018. Its work centres on applying immersive simulation, natural language processing and measurable communication feedback to English-language training across business, higher education, schools and consumer learning.
