Is there a Bunpro for German?

If you have used Bunpro for Japanese, you already understand the idea this page is about, and you can skip to the last section. If you have not: it is worth two minutes, because the concept is the interesting part.

What Bunpro actually does

Bunpro is a Japanese grammar tool built on spaced repetition. Rather than reviewing a card that says "conditional form" on one side, you get an example sentence with a blank in it and type the missing piece. Get it right and the interval lengthens; get it wrong and it shortens. Grammar points are organised by JLPT level, each with an explanation and example sentences, plus reading practice.

The reason people are attached to it is that most SRS tools are vocabulary tools. Bunpro applies the same scheduling to grammar, which is the part of a language that usually gets taught once in a textbook chapter and then quietly forgotten three weeks later.

For reference, as of July 2026 Bunpro is 5 USD a month or 150 USD as a one-time lifetime purchase, with a 30-day trial and a free tier that gives you the grammar and vocabulary pages without the SRS.

It is Japanese only. That is not a gap they have neglected to fill - it is a focused product, and the closest thing to an official answer about other languages is a staff comment from 2022 saying "maybe one day".

Why the question keeps coming up for German

German has exactly the shape that makes grammar SRS worth having:

• Four cases with declension tables that decay from memory very fast.
• Gender that is not predictable from meaning and has to be learned per word.
• Two-way prepositions that change case depending on whether there is movement.
• Separable verbs whose prefix ends up at the far end of the sentence.
• Word order that shifts under subordinating conjunctions.

None of that is hard to understand. All of it is hard to retain and produce under time pressure, which is precisely what spaced repetition is for. A textbook explains the Dativ once. It does not come back and check in four months whether you still have it.

What merke.me is

It is the same shape, for German. We should be upfront that we built it, so read accordingly.

• 444 grammar points, A1 to C2, each with a plain-language explanation in English and German, a structure pattern, and 20-50 example sentences.
• Cloze reviews over those sentences - you type the missing form, same active-recall idea.
• Vocabulary (~13,000 entries) and collocations on the same schedule, so grammar and words reinforce each other rather than living in separate apps.
• Fixed staged intervals from 4 hours to 4 months across five ranks, ending in Master - at which point an item leaves the queue permanently.

The scheduling model is closer to WaniKani's than to a fully adaptive algorithm: predictable intervals and a visible finish line, rather than per-card optimisation.

Honest differences from Bunpro

• Younger product, and a smaller community.
• Bunpro's grammar explanations lean on a mature ecosystem of Japanese-learning references. Ours are written in-house.

Other things people try for German

The usual answers are Anki with a shared grammar deck, or a general course app. Anki is free and more flexible, and if you are happy building your own cards it is genuinely the better tool - we wrote a longer comparison with Anki that says where it wins. Course apps generally explain grammar once and move on, which is the exact failure mode described above.

We are not going to claim nothing else like this exists for German, because we cannot check every tool and someone always knows one we missed. If you have found a better fit, we would genuinely like to hear about it.

Look before you sign up

The content is open - you can read the grammar library end to end, browse vocabulary by frequency and the expressions, without an account. The free tier covers 100 words and 30 grammar points from any level, so you can see whether the review loop suits you before paying.
