Honest comparison · 2026
Bunpro vs Renshuu
Bunpro and Renshuu are both Japanese-specific SRS platforms, and both organise everything by JLPT level — but they specialise differently. Bunpro is built around grammar points, each with example sentences and links to external explanations. Renshuu is far broader: grammar, vocabulary, kanji, and conjugation drills in one system, with a generous free tier.
Bottom line
Bunpro for grammar depth, Renshuu for breadth on a budget
Pick Bunpro if grammar is your bottleneck and you want the best-curated grammar SRS available. Pick Renshuu if you want vocabulary, kanji and grammar in one place and would rather not pay — its free tier covers more than most paid apps.

Worth knowing
Where InputDojo fits
Neither tool is a reader. Both drill items in isolation, which is exactly what SRS is good at — and exactly why grammar you have drilled can still fail to click in a real sentence. InputDojo is the reading half: import an article, video, or story, tap unknown words, and get AI grammar explanations in the context they actually appeared in. Full JLPT vocabulary tracks are free, so it works alongside either tool rather than replacing it.
FAQ
Can I use Bunpro and Renshuu together?+
You can, but the review load doubles and the JLPT vocabulary overlaps heavily. Most people who try both end up keeping Bunpro for grammar and something else for vocabulary.
Is Renshuu really free?+
The free tier is genuinely usable long-term rather than a trial — it is one of the few in this category where paying is optional rather than eventual.
Which is better for passing the JLPT?+
Bunpro maps more directly to the grammar section. Neither covers the reading section well, because both drill isolated items rather than passages — pair either with real reading practice.
