Free Chrome extension to learn Japanese from anime
Searching free Japanese anime extension usually lands you on dual-subtitle tools that assume you already read kana — or paid mining suites. AnimeVocab is free for the habit that matters: one useful word per line, in romaji, with spaced repetition, on the streams you already watch.
Install from GitHub / Chrome (no credit card). Watch Crunchyroll, Netflix, or YouTube. Save romaji-first cards. Review on a schedule. Optional Pro only if you want hosted Listening Mode without your own OpenAI key.
Free tools compared (honest 2026 map)
- AnimeVocab — romaji-first + built-in SRS + Crunchyroll Listening Mode. Best free pick for month-zero learners.
- Language Reactor — free dual subs on Netflix/YouTube if you can read Japanese text (comparison).
- asbplayer — free Anki mining if you bring Japanese subtitle files (comparison).
- Lexirise / ManabiDojo — free cores for readers on Crunchyroll; not romaji-first (vs Lexirise, ManabiDojo alternative).
- Migaku — paid mining suite; if you want free first, see Migaku free alternative.
Why "free" rankings often miss beginners
Most 2026 listicles crown Language Reactor or Animelon without asking: Can you read the Japanese subtitle they require? and Are you on Crunchyroll? If either answer is painful, a free dual-sub tool still leaves you stuck. AnimeVocab exists for that gap — full free plan: learn Japanese with anime free, best apps ranking, and Crunchyroll guide.

FAQ
Is AnimeVocab really free?
Yes. The core loop — romaji-first word cards, local spaced repetition, and watching on Crunchyroll, Netflix, and YouTube — is free with no account required. Pro is optional for hosted Listening Mode transcription without bringing your own API key.
What is the best free Chrome extension to learn Japanese from anime?
It depends on reading level. If you cannot read kana yet or watch Crunchyroll without Japanese subtitles, AnimeVocab is built for that. If you already read Japanese subs on Netflix, Language Reactor's free tier is strong. asbplayer is free for Anki miners who can sync fan subtitle files.
Does the free tier work on Crunchyroll?
Yes. AnimeVocab runs on Crunchyroll simulcasts. When Japanese subtitle text is missing, Listening Mode works from audio so beginners are not stuck waiting for fan .srt files.
Do I need Anki?
No. AnimeVocab includes built-in spaced repetition. Power users who already live in Anki can graduate later to asbplayer, SubMiner, or Migaku.
Is there a full free anime Japanese study plan?
Yes. See learn Japanese with anime free for the AI Overview stack (Language Reactor, asbplayer + Yomitan, Lexirise, Animelon) plus AnimeVocab's beginner/Crunchyroll path and beginner show picks.
