Language Reactor vs Trancy

This page is for people choosing between the two overlay tools they actually type: Language Reactor and Trancy. It is not a Trancy-alternatives roundup, and it is not the 2026 Language Reactor alternatives list. /compare is the hub; this is the pairwise.

Both overlay video you already watch. Trancy also does web/PDF and mobile apps, but those apps are YouTube-only for video — they do not work with Netflix or Disney+. Language Reactor is the Netflix and YouTube toolbox with PhrasePump and Anki export.

Where Trancy Wins

• Disney+ and course sites (Udemy, Coursera, TED, edX) on the canonical eight
• Official Firefox
• Mobile apps (YouTube video only; not Netflix or Disney+)
• Grammar and speaking coach, plus web/PDF

Where Language Reactor Wins

• Netflix and YouTube maturity
• Anki export and PhrasePump
• Language coverage (40+ versus Trancy's narrower set)
• A simpler free dual-sub start on Netflix and YouTube

The Gap Both Leave

Prime Video. Language Reactor does not support it. Trancy's canonical docs list of eight does not include it either. FluentAI covers Prime Video and HBO Max, ships official Firefox, and includes built-in flashcards on the free plan, without Trancy's translator sprawl. Sentence mining on FluentAI is paid (20/day on Basic, unlimited on Pro). Neural transcriptions are Pro.

Who Should Pick Which

• Pick Trancy if Disney+, course sites, or official Firefox matter more than Prime Video. Trancy mobile video is YouTube-only
• Pick Language Reactor if you only need Netflix and YouTube in Chrome and want the mature free overlay
• Pick FluentAI if you also watch Prime Video or HBO Max, want official Firefox, and want watch-click-save-review with free flashcards
