Watch and read

Bring language help to what already has your attention.

Use Benkya over supported video or on an ordinary webpage. Choose the smallest tool that helps, then keep watching or reading.

Preview

Two subtitles, one calm view

Read two source-provided tracks together on Netflix, YouTube, and compatible HTML5 video.

Preview

Read the wider web

Select a word for Quick lookup, translate a nearby passage, or add Japanese furigana without leaving the page.

Make subtitles yours

Script-aware reading

Read it in the notation that helps you.

Benkya treats reading support as part of the language—not as one generic romanization layer.

Preview

Japanese furigana

Add reversible readings to Japanese webpage text and supported subtitles.

Preview

Pinyin or Bopomofo

Choose Hanyu Pinyin or Bopomofo, with automatic, Mainland China, or Taiwan pronunciation.

Beta

Help for ambiguity

Deterministic readings come first; signed-in AI is reserved for candidates that need contextual disambiguation.

Dictionary first

AI when context adds value.

Quick lookup can stay deterministic and free. Contextual explanation is a separate, clearly labeled action when a scene or sentence changes the meaning.

01

Reference

Licensed-source and Benkya-reviewed entries, meanings, readings, examples, and visible attribution.

02

Context

Optional explanations can cover scene-specific meaning, nuance, grammar, and the surrounding line.

03

Clear provenance

Dictionary content and generated fields stay visibly distinct instead of being presented as the same kind of fact.

Your data, your exit

A learning record should remain yours.

Benkya is designed around explicit actions, narrow data flows, and portable study material.

Design principle

Deliberate, not passive

Looking up or saving an expression is a learning signal. Merely displaying a subtitle is not.

Design principle

No video or audio upload

Hosted language actions receive bounded text needed for the request—not the audiovisual stream.

Beta

Protected learning records

Sensitive saved words, context, notes, and progress are protected with application-layer encryption.

Take decks to Anki

Export a dynamic deck as a bounded, text-only Anki .apkg instead of locking it inside Benkya.

Netflix and YouTube are reviewed platforms. Benkya also supports generic HTML5 video when a website player exposes standard subtitle tracks. Compatibility continues to expand as more players are added.

Generic HTML5 video — standard subtitle tracks only. Compatibility continues to expand; embedded, custom-rendered, or burned-in captions may not work.

Benkya is independent and is not affiliated with, endorsed by, or sponsored by Netflix, YouTube, or other video websites. Availability may change when a provider changes its player or policies.

The useful details before you start.

What does Benkya stand for?

Benkya combines benkyō (勉強)—the Japanese word for study—with “a” for assistant: a study assistant that stays quietly in the background.

Do I need an account?

No. Local mode can display subtitle tracks supplied by a supported streaming source and keep unsynced captures on your device. An account will be needed for cloud saves, personalized AI, review, export, and billing.

Does Benkya download the video or audio?

No. The add-on is designed to work with the streaming player and its available subtitle cues. It does not download or redistribute audiovisual content.

What happens when my language is unavailable?

You can request AI translation for the relevant subtitle text. The interface will distinguish source-provided subtitles from generated translations.

Does Benkya support generic HTML5 video?

Yes. It works with visible HTML5 players that expose standard subtitle or caption tracks. Embedded players, custom-rendered captions, and subtitles burned into the image may not be detected. Compatibility continues to expand, and learning tools can vary by site.

Which interface languages are available?

The interface is available in English (US), Japanese, Traditional Chinese, Latin American Spanish, and Brazilian Portuguese. Learning and subtitle languages are configured separately.

Can I use my cards outside Benkya?

Yes. Member tools are designed to export Anki .apkg at launch, with CSV/TSV and JSON options as well.

Every good line can be a lesson.

Benkya is being built to help you notice it, understand it, and meet it again at the right time.
