Honest comparison · 2026
WaniKani vs Renshuu
WaniKani is an opinionated kanji curriculum: 60 levels, custom mnemonics for every radical and character, and a schedule you follow rather than configure. Renshuu is a broad Japanese SRS covering grammar, vocabulary, kanji and conjugation, with far more flexibility and a free tier that most competitors cannot match.
Bottom line
WaniKani for a path, Renshuu for range and price
Pick WaniKani if decision fatigue is your enemy and you want to be told exactly what to study for the next year. Pick Renshuu if you want to control your own order, cover more than kanji, and pay little or nothing.

Worth knowing
Where InputDojo fits
Both teach kanji out of context, which is the efficient way to learn them and the reason recognising a character in isolation does not mean you can read a paragraph containing it. InputDojo supplies the paragraph: import real Japanese, see unknown-word density against what you already know, tap for readings and meanings, and ask for an explanation of any sentence. Full JLPT vocabulary tracking is free, and it does not care which SRS you use alongside it.
FAQ
Is WaniKani's fixed order a problem?+
It is the feature and the complaint. You cannot prioritise the kanji in the book you are reading now, but you also never have to decide what comes next.
Can Renshuu replace WaniKani entirely?+
For content coverage, yes. What it does not replicate is WaniKani's consistent mnemonic system, which is the main reason people stay.
Which is better for JLPT?+
Renshuu, because it covers grammar and vocabulary as well as kanji. WaniKani's ordering is its own, not JLPT-aligned.
