What is Yomimaru and how does it help learn Japanese?

Yomimaru is an interactive Japanese reading platform designed to help intermediate and advanced learners transition to authentic native texts. It tokenizes Japanese sentences instantly to provide context-aware dictionary lookups, customizable furigana displays, spaced repetition practice tools, and AI grammar parsing to explain particles and embedded clauses in real-time.

Does Yomimaru support custom web novel or light novel uploads?

Yes, through the Content Studio, Yomimaru allows users on premium plans (Samurai and Shogun) to import their own custom light novels, web stories, and text files. Yomimaru parses and tokenizes the custom text, automatically converting it into clean, interactive chapters optimized for vocabulary lookups.

How does AI Maru-Sensei assist with Japanese grammar?

Maru-Sensei is our built-in AI tutor. It analyzes complex native sentences to break down their grammatical components, explain particles like wa and ga, isolate relative clauses, and host conversational, sentence-specific question and answer threads directly within your reading view.

Why Yomimaru is Different

Flashcards build vocabulary in isolation. Graded readers keep the training wheels on. Neither gets you reading the books you actually want to read.

Sentence Breakdowns	✅ Maru-Sensei parses complex clauses in real-time	❌ No grammar feedback; requires external lookup	❌ Static text without explanations
