Machine learning breaks sentences into clauses, tags each part of speech and maps the modification relationships between short clauses so you can see how a sentence is built.
Kanji are annotated with readings, and a built-in dictionary resolves conjugations and inflected forms automatically as you read.
Online translation and adjustable-speed text-to-speech sit next to a camera OCR workspace that handles vertical text and manga layouts.
Import EPUB e-books or let the app parse the contents of a web page, so study material does not have to be retyped.
Bookmark paragraphs and new words for later review, and work through an interactive introduction to Japanese grammar.
Oyomi targets learners who can handle vocabulary drills but struggle to read real-world Japanese. Instead of copying sentences into a search box one word at a time, you paste or import text and the app breaks it into clauses, tags parts of speech, annotates kanji with readings, and generates a semantic breakdown that shows how short clauses modify one another. The result is a reading surface rather than a quiz.
The app goes beyond a single text box. It can parse web pages you browse to, import EPUB e-books for long-form reading, and use the camera for OCR of printed text, including vertical text and manga layouts. Translation and text-to-speech are built in, so a sentence can be read aloud at a chosen speed while you compare it with the English meaning.
Study features tie it together: a vocabulary notebook lets you bookmark sentences and new words for later review, and an interactive course covers introductory grammar alongside common grammar references. Oyomi is free to download with in-app purchases, is distributed by an independent developer (楷雯 周), and continues to receive frequent updates.
Work through novels, news or blog posts with sentences automatically segmented and glossed, so you spend time reading rather than searching.
Photograph printed Japanese and let the OCR workspace, with vertical text support, produce parsed, readable text.
Use the semantic view to see how subordinate clauses attach to one another when a sentence is too long to parse by eye.
Play sentences aloud at an adjustable speed and follow the annotated text to train both comprehension and pitch.
