The system map

Serious learners duct-tape four apps together.Mogoru is all four.

Learners glue these tools together with plugins, exports, and copy-paste — and the glue always breaks. Mogoru builds them on one shared vocabulary: a word you tap while reading is the same word on your flashcard, and the same word your tutor knows you know.

A reader

that tracks every word you meet

A dictionary

one tap away, built in

Flashcards

with real spaced repetition

A tutor

who remembers what you've learned

One shared vocabulary

The same word, everywhere it matters.

The Reader

A reader that tracks every word you meet.

Bring pasted text, EPUBs, PDFs, manga, or plain images — up to 512 MB per file. Mogoru highlights every word by how well you know it, and one tap opens the dictionary, frequency rank, and conjugation breakdown.

  • One tap: word → dictionary → flashcard, linked to the exact sentence
  • i+1 jump: skip to the next sentence with exactly one unknown word
  • Furigana and inline glosses, toggle anytime
  • Comprehension % and difficulty rating for every document
  • Sentence Assist: translate, break down grammar, or make a card

Manga

Manga is not an afterthought.

Drop in a .cbz or a scanned PDF. Mogoru reads the page with built-in OCR — no plugins, no extra tools — and turns every speech bubble into tappable words right on the artwork. Flip any bubble to a natural AI translation, typeset back into the bubble itself.

  • Built-in OCR with manga-aware reading order
  • Word-level hotspots on the page — tap to look up, tap to save
  • AI bubble translation with in-bubble typesetting and an Original/Translated toggle
  • Mokuro files supported
  • Handles both scanned and text PDFs — and fixes garbled text automatically

まだが
ね。

Tap a dotted word on the artwork to look it up.

Flashcards

Full-featured flashcards. Zero lock-in.

Under the hood: FSRS, the modern spaced-repetition scheduler, with per-deck retention targets and custom weights. Around it: advanced deck management and review controls, with .apkg import and export in both directions.

  • Import and export Anki .apkg deck files with scheduling history intact
  • Note types, custom fields, card templates and CSS, cloze
  • Advanced browser search, bulk actions, suspend, bury, and leech handling
  • Stats that tell the truth: heatmap, due forecast, true retention
  • Cards born from real sentences you actually read

AI Tutor

A tutor that knows your words.

Not a chatbot bolted on. Mogoru's tutor reads a live snapshot of your level, known words, and due cards — and it can act: tell it you know a word, and it updates your vocabulary. Ask for practice, and it writes at your level.

  • Live awareness of your vocabulary and progress
  • Acts through tools: looks up words, updates statuses, creates flashcards
  • Adapts difficulty to what you can actually read
  • Every action is visible — watch it look up words and file cards in real time

I keep seeing pleuvoir in this chapter — I think I've got it now.

set_word_status · pleuvoir → known ✓

Marked pleuvoir as known — that's 214 words now. Since you know la pluie and pleuvoir, try this:

Il pleuvra sans doute encore demain.

What's sans doute doing here?
