## What is Tomaru?

If you're not reviewing, you're not really learning.
No review system = no retention.
Tomaru uses spaced repetition to make vocab actually stick.


**How Tomaru helps you truly learn a language**

[Spaced Repetition Vocab]
Built on the FSRS algorithm — so you stop forgetting what you've studied.
Ever crammed a ton of material, then blanked when it actually mattered? Science shows two things make memory last: relearning right before you forget, and actively recalling it at that moment. That's exactly what Tomaru's system does.
Study less. Remember more.

[Ready-Made Decks]
Decks for languages, exams, and everyday life — free, no limits. Every card has images, example sentences, part of speech, pronunciation, audio, and word root hints. Pick a deck that fits your level and goal. No more hunting for vocab lists.

[Add Vocab in One Tap]
Song, article, textbook — paste it in. Tomaru pulls out the vocabulary and builds your personal deck instantly.

[AI Practice]
All exercises are built around vocab you've already learned.
Shadowing — repeat after real native sentences to sharpen listening and speaking
Translation — AI generates passages at your level; translate them and find your weak spots, with AI feedback on every attempt
Grammar drills — targeted questions on the nuances that trip people up, with full AI explanations

[Immersive Focus]
Mix ambient sounds (rain, city, fireplace) to get into flow fast.
