Why anime, not live-action dramas

English anime is easier to stick with

Foreign live-action dramas move fast and lean on cultural context that's easy to miss — a common reason learners give up. English anime tends to be more approachable, with clearer, slightly slower dialogue and tidy 20–30 minute episodes. Start with anime, build comfort, then step up to live-action dramas whenever you're ready.

Card creation, without the busywork

Zero time spent making cards

With tools like Anki, making flashcards one by one is the work that stands between you and actually studying. With Hitaru, save a phrase you notice with a single tap while you watch — no card-making required, so watching and remembering happen at the same time.

Seeing your progress

Watch your vocabulary grow

Just watching and listening rarely lets you feel how much vocabulary you're actually picking up. Hitaru visualizes today's reviews, your cumulative reviews, and an estimated level in one place, so your progress is something you can actually see.

Deciding what to save

Know the difficulty before you decide to save

Wondering whether a phrase is worth saving slows you down. Hitaru shows an Eiken/TOEIC-equivalent difficulty level right when you're deciding whether to save it — or just save everything and filter by difficulty in your deck later.

よくある没入学習ツール

Hitaru

Simple on purpose

Fewer features, easier to keep going

Immersion tools tend to pile on features and settings until they get in the way. Hitaru deliberately keeps things minimal, so it's approachable even if you're new to English learning or not into fiddly configuration.
