Phnom Penh · Cambodia — Khmer & English
From everyday user to AI builder.
RinAI trains Cambodians from non-technical to technical. Every session ends with something you built: a Gemini assistant, a trained model, an AI agent. Made in កម្ពុជា.

Teaching from the research frontier of Khmer AI
At ICDAR 2026, the International Conference on Document Analysis and Recognition, Rina and colleagues from Techo Startup Center and Osaka Metropolitan University presented Towards Universal Khmer Text Recognition and Towards Khmer Camera-Captured Document Layout Detection. Rina is Principal Investigator on a JSPS KAKENHI project (2026–2029) extending this work to other Asian low-resource languages, and a member of the JST CRONOS project. The same work feeds straight into class: learners fine-tune Khmer OCR models themselves.
