this iskotomori.
A little forest of small, thoughtful apps about language, learning, and the quiet joy of a child finding the right word.
Language isn't a subject. It's the soil every other thing grows in — a song, a story, a shared joke between generations.
kotomori gathers apps that treat words with the care they deserve. Not drills. Not streaks. Small tools that make language feel alive again — for a six year old tracing their first kanji, for an adult catching their hundredth shadow on a YouTube video, for a family inventing a new word at dinner.
Small tools, quietly made.
Each one does a single thing, gently. Use one, all, or none — they're better together, but they don't insist.
SubTube
language in every videoReal-time captions, tap-to-define dictionary, and shadowing practice layered over any YouTube video. Learn with what you already love.
Oekaki Anime
drawings, aliveYour child's drawings, gently animated and bound into picture books. A quiet iPhone app for an afternoon together.
Nazori
tracing, patientlyHiragana and kanji, one stroke at a time. For first graders and Japanese learners around the world, with feedback that feels like a teacher, not a score.
LiveCap
captions for everythingAnything playing on your Mac — a meeting, a film, a podcast — captioned and translated in real time, privately on device when possible.
Daily English Article
one article, every dayA single, readable English news piece every morning. No notifications clamoring. Just something quiet to read with coffee.
Memoria
your AI, your memory, on your own devicesA local AI chat that quietly remembers your conversations — on Mac and on iPhone. Nothing leaves your device.
Made in Japan, spoken everywhere.
Every app and every page ships in Japanese, English, and Spanish from day one — with more languages always on the way. Language should never be the thing standing between you and a good tool.
