In development · iOS & Android

Read the books you love, in the language you're learning.

Yomou turns your digital library of comics, manga, and (soon) ebooks into a personal language tutor. You bring the stories. We handle translation, grammar, and review.

How it works

Four steps from opening a book to remembering it.

01

Bring your library

Import local files from your device or connect a Komga server. Auto-grouped into series, with covers and progress sync.

STEP · IMPORT
02

Read in flow

Single-page, double-page, or webtoon scroll. Smooth zoom and smart navigation, with RTL or LTR per book.

STEP · READ
03

Ask anytime

Tap a bubble for a focused breakdown, or summarize the whole page. Save what matters and review it on a schedule.

STEP · ANALYZE
04

Study what you saved

Saved words and sentences go into decks you can review with flashcards, at your own pace or guided by spaced repetition.

STEP · STUDY
Features

Built for readers who happen to be learning a language.

Yomou is a reader app first. The learning tools stay out of the way until you ask for them, and step aside the moment you're back in the story.

One library, many sources

Browse everything together: local CBZ and EPUB files, plus remote Komga shelves. Series grouping, cover thumbnails, search, sort, and reading progress that follows you between devices.

Page analysis

Get a panel-by-panel breakdown of any spread. Summary, dialogue, and a grammar pass for every speech bubble.

Selective lookup

On-device OCR finds the bubbles. Tap one for a focused, low-cost analysis without leaving the page.

Grammar that teaches

Every sentence comes with phonetics, multiple translations, and a grammar breakdown that explains the why, not just the what.

Flashcards that speak

Review every saved word or sentence as a flashcard. Tap to hear it read aloud with neural text-to-speech. Phonetics included for Hiragana and Romaji.

The Study tab

Make a saved word yours.

Every word and sentence you save goes into a deck of your choice. Browse it like a notebook, or let a spaced-repetition session pick what to show you next. No streaks to keep, no guilt for skipping a day.

01

Decks for what matters

Group saved items by series, character, theme, or language. Browse the full list, refresh memory at your own pace, or queue a deck up for review.

02

Spaced repetition, gentle by default

An SM-2 schedule decides what you see and when. Miss a card and it loops back later in the same session. Mastered decks export to Anki.

Sources & formats

Bring what you already own.

No catalog, no DRM, no walled garden. Yomou opens the files on your device and connects to the open formats and servers you already use.

Local files

Import folders or individual files straight from device storage. Files stay on your phone.
