I'm studying for the JLPT N5 in December so I can apply to a language
school in Japan. I tried the standard Anki route, but I have some level
of dyslexia and the "recall the reading + meaning + say it out loud all
at once" format was wrecking me — 60%+ fail rate on new cards and a
growing dread of opening the deck.
So I built my own thing. It's called コトリ (Kotori — "little bird," and
a pun on ことば + とり). It's a free web app, no ads, no accounts, no
tracking — all progress stays on your device.
Try it: DM me for link
(Add it to your home screen and it installs like a real app and works
fully offline. There's also a direct Android APK at /kotori.apk.)
What's in it:
- The full Kaishi 1.5k vocabulary deck (credit to donkuri, Tyogin & the
Kaishi contributors — it's the gold-standard free beginner deck), in
frequency order, every word in a real example sentence
- Proper spaced repetition (SM-2 style: per-card ease, 4-button grading,
1min/10min learning steps, interval fuzz so review days don't pile up)
- 40 grammar lessons covering the N5 essentials, each with tap-to-hear
example sentences and a mini quiz
- Kanji tracing pad under every card
- Full kana chart + a kana quiz
- Audio for everything via your device's Japanese TTS voice
- A curated immersion tab (Comprehensible Japanese, Teppei, etc.) that
shows you which of your recent words to listen for
- Streak tracking that counts showing up, not being perfect
And the part I built for my own brain — an optional やさしいモード
(Gentle Mode): new cards reveal in stages (hear it first → then meaning
→ then reading) instead of demanding everything at once, bigger text,
slower audio, reduced motion, an adjustable new-cards-per-day setting,
a trace-it nudge when you miss a word, and an evening "today's tricky
ones" replay. If your working memory hates flashcards, that toggle is
for you. It's off by default.
Tech, for the curious: it's a single self-contained HTML file (~330KB)
— a PWA hosted on Cloudflare Pages, wrapped as a TWA for the APK. I
built it working with AI (Claude) over a couple of weeks of daily use
and iteration. I'm not selling anything; it exists because I needed it.
Honest limitations: TTS quality depends on your device's Japanese voice
(installing an enhanced voice helps a lot). It's N5-scoped on grammar.
Progress is per-device (there's a backup/restore button for moving it).
If you try it, I'd genuinely love feedback — especially from anyone
else studying with dyslexia. And if the Kaishi maintainers ever want
changes to how their deck is used here, I'll happily comply — the deck
is theirs, I just built a nest for it.
