First 2000 Sentences of Japanese Foundation Deck Ready for Beta!

After a successful closed beta, we're releasing the first 400 sentences of the Japanese Foundation deck into open beta today. We're also launching a larger closed beta of the first 2000 sentences. Apply for that here.

As a reminder, the Japanese Foundation deck is a collection of ten thousand LN sentences that starts simply and gradually introduces a huge amount of vocabulary and grammar. It's designed to take you from beginner to late intermediate in one go.

For context, the first sentence is 俺はわかる。, the 400th sentence is 空気を切るような音が響いた。, and the 2000th sentence is もちろん、もしぼくの状態が悪くなって、何もできなくなったら、あとは先生が中心だから、ぜんぶおまかせします。. If you're curious to see more example sentences and broad information about how the deck is structured, check out Japanese Foundation: Structure. You might also be interested in our broader goal of bringing scientific rigor to the Japanese Learning community.

The deck is available (for free) on quantized.co, our next generation spaced repetition platform. (Quantized provides per-card comments, and uses aggregate review data to dramatically improve the spacing algorithm.) The sentences are also available for personal use under a creative commons license on GitHub here.

FAQ

How are you making money off of this?

We're selling deck add-ons, like native audio.

What's the licensing?

We understand that you want to keep control of your cards, so the sentences are free for personal use. Specifically, we're releasing the first 400 under an (unrevokable) CC BY-NC-ND license today, so you can be confident in your continued use of them.

How are these sentences checked?

The Japanese sentences are taken as-is from published light novels. We're in the process of hiring a professional proofreader to verify the furigana and English translations.
