Migaku vs Language Reactor

Language Reactor is dual subtitles and a dictionary on Netflix and YouTube, plus PhrasePump and Anki export. Migaku is parse-and-click native media, one-click cards, and Migaku Memory SRS. Japanese is the flagship. Chrome only. They are different jobs.

This page is the pairwise. The existing Migaku alternative guide is the "Migaku is heavy, what else?" roundup. Link that if you want to leave Migaku. Do not turn this page into that roundup.

Pick Migaku If

• Daily mining is the point
• You want Anki or Migaku Memory as the review system
• You watch Disney+ on Chrome
• Japanese depth (pitch, parsing) is why you showed up

Pick Language Reactor If

• You only need Netflix and YouTube
• You want a usable free overlay
• You do not want Migaku's stack

A Lighter Third Option

FluentAI is watch, click, save, built-in flashcards, plus Prime Video and HBO Max and official Firefox, without Migaku setup. Flashcards are free. Sentence mining is paid (20/day on Basic, unlimited on Pro). Neural transcriptions are Pro. This page must not become the leave-Migaku roundup.
