HayaiLearn for Web

What HayaiLearn Does

HayaiLearn is a subscription web app that leverages AI to make learning Japanese through YouTube videos more effective and engaging. It turns passive watching into active study by layering interactive tools on top of existing video content, helping learners build vocabulary, understand grammar, and retain what they hear.

How the interactive subtitles work

• Hoverable captions let viewers bring up instant pop-ups for individual words and phrases, providing concise definitions and usage notes.
• Clickable terms reveal deeper explanations, including grammatical context and alternate meanings tailored to the clip’s situation.

Library and content variety

• A growing collection of over 800 videos spans formats such as anime, vlogs, and short clips, so learners at different levels can find material that suits their interests.
• Curated examples from the library are used to demonstrate real-world usage of vocabulary and grammar points directly within the app.

Practice tools and study features

• The platform supports sentence mining: users can save subtitle lines for later review and build personalized study sets.
• Video-based quizzes reinforce comprehension by testing vocabulary and grammar in the context where they appeared.

Progress tracking and learning analytics

• Users can monitor their development with tools that record vocabulary learned and grammar topics reviewed over time.
• Personalized review schedules and performance summaries help prioritize what to study next.

Improved caption accuracy

• HayaiLearn enhances the default YouTube auto-captions, offering cleaner, more accurate transcriptions designed for study rather than casual viewing.

Why learners benefit

HayaiLearn blends contextual exposure with active study: authentic video content keeps engagement high while interactive definitions, curated examples, and review tools convert exposure into lasting knowledge. The mix of content types and targeted practice features makes it useful for beginners through advanced learners who want a practical, video-centered approach to Japanese.
