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 (Anki export optional — Memory is first-class). Japanese is the flagship. Chrome only. They are different jobs.

This page is the pairwise. If Migaku feels heavy and you want out, use /guides/migaku-alternative — do not turn this URL into that roundup.

Pick Migaku if

• Daily sentence mining is the point
• You want Migaku Memory (or you already live in Anki via optional export)
• You watch Disney+ on Chrome and do not need Prime / HBO Max / Firefox
• Japanese (or similar) parsing depth is why you showed up

Pick Language Reactor if

• Netflix + YouTube on Chrome is enough
• You want a usable free overlay without Migaku's stack
• PhrasePump + Anki export matches your current habit
