Japanese learning through stories and subtitles

iago is a Japanese learning product that combines story-based lessons, conversation practice, and subtitle-driven study. The homepage positions it as a way to start speaking Japanese from day one, using an open-world curriculum that helps learners move through everyday situations and real-world phrases.

The product also includes a browser extension for learning from shows. On the extension page, iago describes subtitle interaction, dictionary lookups, and quiz-based review as ways to discover and retain vocabulary while watching content. The overall experience is designed for learners who want contextual practice instead of a textbook-only approach.

Core features

Story-led curriculum

Guided Japanese lessons are presented as an open-world curriculum that starts with beginner basics and progresses through contextual lessons rather than isolated drills.

Situation-based practice

The homepage says learners choose real-life situations and work through interactive visual stories, which gives lessons a scenario-based structure.

Conversation and pronunciation feedback

The site highlights listening and speaking practice through conversation with Iago and Iako-Chan, plus immediate pronunciation feedback.

Subtitle word lookup

The extension page describes annotated subtitles that let learners hover over a word to see its definition, difficulty, frequency, and related information.

Dictionary and review tools

The extension also includes dictionary access for other definitions, inflections, and progress tracking tied to words you have seen.

Quiz-based retention support

The extension promotes randomized quizzes and spaced repetition to reinforce vocabulary, reading, and listening skills.
