azVocab is a Vietnamese-language platform designed to support English vocabulary acquisition through scientifically grounded methods. The tool addresses the challenge of long-term vocabulary retention by applying spaced repetition techniques and incorporating research from neuroscience and linguistics. Users can build and manage their own personalized vocabulary notebooks, adding words they encounter during study, exam preparation, or leisure activities such as reading news or watching films.
Key features include the ability to quickly add new words to a personal vocabulary list, either individually or from curated lists tailored to popular exams and textbooks. The platform utilizes a sophisticated, personalized spaced repetition algorithm to prompt users to review words just before they are likely to forget them. Question types are adapted to each stage of the learning process, drawing on research by Professor Paul Nation to ensure that review sessions are both effective and appropriate for the learner’s progress. The tool also offers clear progress tracking, including transparent reports and vocabulary mastery indicators, as well as motivational aids such as reminders, calendar notifications, and competitive features for learning alongside peers.
azVocab is accessible across multiple devices, including smartphones, laptops, desktop computers, and tablets, enabling users to study vocabulary anytime and anywhere. The service is easy to use, allowing for quick word lookup and addition, and is designed to fit into short, focused study sessions. The platform is developed by CTH SOFT JSC, a company based in Hanoi, Vietnam.
The tool offers a free registration option, allowing users to begin using its features at no cost. azVocab has been recognized as an innovative educational initiative at the “Thắp Lửa Cùng Tiến Lên 2025” conference, organized by EduLightenUp and the Institute for Research & Development of Educational Management, and has received positive evaluations from teachers and educational administrators for its effectiveness in optimizing vocabulary learning and supporting instruction.
