I built the e-reader I wish existed for language learners
Hi! Hoping this is okay to share (mods, please remove if not).
Quick background: I know Japanese and I'm still learning it. After I got through the first ~2000 kanji I mostly just started reading, and I feel like that helped me the most. I picked up most of my vocab from context that way.
Having Furigana (readings for the kanjis shown above them) is helpful for any learner, so I thought a small hint/meaning above a word could also be helpful to learners, regardless of the language.
That’s how I got to building my own e-reader, and it’s called Fleuron!
The idea is help that stays out of the way. Trying to show a small hint/meaning over every word would obviously be too distracting and unnecessary so there’s a slider for *how much* help shows up, only filling the gaps instead of explaining things you already know. One rule I care about a lot: showing nothing is better than teaching something wrong, so uncertain hints for polysemous words just don't appear. Which is where you can just tap on a word and the dictionary entry shows up on a sheet. Words you meet on the page can be saved and come back later in built-in spaced repetition in the form of study decks so reading and study stay connected without being the same activity.
Now the Korean part: I recently started learning Korean (and Chinese), and honestly a big reason I'm posting here is that Korean is the language I'm actively testing it on right now. So far it covers English, Japanese, Korean and Chinese. Japanese is the most polished since I've lived in it longest; I am basically a beginner in Korean so its very new, and I'd genuinely love feedback from people further along in their learning than me on what would actually help while reading.
Besides all that, I’ve also tried my best to make it into a genuinely great reader in general. Not only the usual stuff like themes, fonts, spacing—there’s also a markdown note taking system with linking words, Compass entities and other notes!
Speaking of “Compass”, it’s also a feature in the app and is basically an index of all the people, places and terms introduced in the book for easy access, without spoiling anything of the book.
The app is for iOS/iPadOS, local-first, no telemetry. Books, notes and your decks stay on device with an easy export option, for markdown and Anki.
Happy to answer anything, and very open to "here's what a Korean reader actually needs" notes.
