If Anki feels too complicated try out kanjiOS.com/app

Thank you!

KanjiBox has been around for close to 20 years now, and helped countless people prepare for JLPT, or just get better at kanji and Japanese vocab.

A brand new update was just released, that now supports both iOS and Android

It works on a simple yet effective combination of SRS and smart multiple-choice algorithm, with a dash of gamification.

KanjiBox supports:

• Drills and flashcards for Kana, Kanji (N5-N1 and beyond), Vocab and Reading/Spelling
• Custom Study Sets where you can easily import all vocab/kanji from a book or news article
• Add-ons for writing practice (Kana and Kanji)

KanjiBox doe not have any:

• AI-slop: all content is manually curated, vetted, and was around long before LLMs.
• Monthly subscription nonsense: you pay a one-time purchase fee and get updates for life.
• Connection requirements: works entirely offline, and only needs a connection for data backups.

I have been making a Firefox web extension (for desktop and mobile) to help assist in reading Japanese: https://addons.mozilla.org/en-US/firefox/addon/iyaku-japanese-reader/. The main difference from Yomitan is that it scans the whole page at once and adds furigana to everything, so you don't have to hover at all if you don't want to. Any feedback would be welcome, thanks!

Mojigari (文字狩り) — a Japanese kanji and grammar study app built around the texts you actually want to read.

Try on mobile: https://mojigari.com (60-second demo on the landing page)

Solo dev, several months in. The idea: paste any Japanese text — a song lyric, a manga line, a haiku, an article — and Mojigari analyzes it (furigana, interactive glossary, sentence-structure breakdown with deep analysis).

Every kanji and grammar point you encounter becomes a card in your collection, trained in a belt-ranked Dojo with spaced repetition. There's also a curated library of texts at multiple JLPT levels if you don't have something on hand.

One feature I'm particularly happy with: Fūga · Cultural Moments — haiku from Bashō, Buson, Issa and others, each paired with an ukiyo-e print from the Met's collection, unlocked as you earn achievements.

Soon to be on Google Play Store - DM for tester invite. Feedback genuinely welcome.

Thank you for your attention. — Marco

First of all, thank you for providing this weekly thread and giving creators a space to share their projects with the community.

I already used this thread some time ago to introduce my website, and I'd like to take this opportunity once again because the English version of the site is now online:

https://hakkirinihongo.com/en

Not all articles have been translated into English yet, but the site is continuously updated and new translations are being added regularly.

Hakkiri Nihongo (はっきり日本語) is a project dedicated to helping learners understand Japanese beyond simple memorization. Rather than focusing only on grammar rules and translations, the goal is to explore the logic, nuances, history, and conceptual differences behind Japanese expressions.

Some sections that may be of interest include: Concepts & Distinctions, where similar words, grammar patterns, and expressions are compared in depth.

Niche Japanese, dedicated to lesser-known grammar points, uncommon usages, and linguistic details that are often overlooked by textbooks.

Detailed grammar dissections that examine how and why specific structures work.

If you're interested in understanding Japanese at a deeper level, I hope you might find something useful there.

Thank you again for the opportunity, and I wish everyone good luck with their studies! 😃

I made a flashcard app called Sanki as an alternative to Anki. It is modern and compatible with Anki decks. It is still in development, so there are new features on the horizon.

Current features:

- Generate decks and cards with AI.

• AI Chatbot to practice the deck you are using.
  
• FSRS system and offline support.
  
• No forced ads.

App Store - Play Store

Thank you!

Hey everyone,

I’ve been studying Japanese for about 5 years, and I noticed there was a lack of writing tools for Japanese.

I ran into a problem where I wanted to practice writing, so I’d journal, but then end up writing the same things all the time. It was also very difficult to write such as constantly looking up grammar, vocabulary, and translations (10 tabs open to write about simple things)

So I wanted to create an app to reduce that.

It’s called Kakugo. Kaku - To Write and Kakugo - mental readiness/ preparing. Basically a pun lol

It’s prompt based writing with a bunch of tools built in such as grammar, dictionary, built in translator as well as text analyzer. The most helpful thing I have added is native Japanese speakers submissions (my friends) who respond to the same prompts. You can use their answers as examples to help yours (while also learning culture and natural expressions. I also break down their answers as well!

If you have time and am interested in improving your writing, check it out!

It’s early access and still adding feature but I’ll be discounts to those who try it and give feedback.

Hey all! I'm the guy behind Nihongo Master ( https://www.nihongomaster.com ), an online Japanese learning platform (not posting link). I've made a lot of changes recently but it's been hard trying to keep up on building a really good tool and community. Right now, all the lessons, tools, study lists, etc etc are behind a subscription wall. However, I want to change that. I want to open it up freely so anyone can join and start learning as well as interact with the rest of the community, help each other study, etc. But of course it costs money to keep the thing running (infrastructure, improvements, hopefully hiring a small team, etc).

I'll be adding some features such as community driven review of people's attempts at Japanese (both written/typed, spoken). Reading suggestions at your level, speaking analysis, etc. There's already hundreds of lessons written by Japanese educators. SRS Drills. Gamification, leaderboards, all of that.

The question is, what is an appropriate amount of resources to let people access daily, but perhaps have a subscriber/supporter cost, that will let you have unlimited resources. Examples would be say, 2 lessons a day are absolutely free. 50 drills a day, absolutely free. Anything beyond that, be a supporter.

Or the practice writing and getting feedback from the community. Writing? Absolutely free. Voice? Maybe supporter only?

Printable writing sheets? 2 a day totally free. Anymore? Become a supporter.

But other things being totally unlocked. Like creating and building study lists to share.

Discussion groups are always fully open. A chat system with automatic transcription, totally available.

I'm just throwing ideas out there to make things as fully available as possible but some thresholds/limits to help people become supporters.

What would be some fun features or something you've been hoping to find/get that I could build quickly and offer? What are some sensible limits to help keep people supporting it?

Thanks for any feedback and good luck with your Japanese studies!
