Why InputDojo
Satori Reader is the best curated graded reader for Japanese: professionally written stories, superb human-narrated audio, hand-written grammar notes on nearly every sentence, and furigana that adapts to the kanji you know. InputDojo doesn't try to out-curate that — instead it opens up the same read-tap-save workflow to anything: news articles, YouTube videos, blogs, PDFs, in Japanese and 13 other languages. Satori gives you a perfectly graded garden; InputDojo hands you the tools for the wild.

FAQ
Is InputDojo's content graded like Satori Reader's?+
No — Satori's stories are professionally written for learners, which is its biggest strength. InputDojo instead shows unknown-word density per imported article, so you can judge whether real-world content is at your level before committing to it.
Should I use Satori Reader or InputDojo first?+
They stack well: Satori Reader is ideal from upper-beginner through intermediate Japanese thanks to its grading and grammar notes. InputDojo takes over when you want native content — and covers the JLPT vocab/kanji study Satori doesn't.
Does InputDojo have human-narrated audio?+
No — imported text uses text-to-speech, and YouTube imports keep the original audio. Satori's human narration is genuinely better for pure listening practice.
