Review summary

Users like the add-on for broad site support and helpful dual subtitles with translations, especially for language learning. However, recurring issues include unreliable subtitle loading, inconsistent performance across videos and platforms, onboarding friction due to credit-card requirements, incomplete support on some services (like Amazon Prime), and limited customization with some UI/navigation quirks.

Pros

Broad compatibility across sites (works on Netflix, YouTube, HBO Max and others).
Dual subtitles with translations and automatic translation features.
Helpful for language learning, especially English.
Customizable subtitle behavior and settings.
Enhances viewing of original-language content.

Cons

Subtitles sometimes fail to load or translate, reducing usefulness.
Reliability is inconsistent and the extension can stop working across videos.
Dashboard access requires entering credit card information, which deters usage.
Not all advertised platforms work (e.g., Amazon Prime) and some site support is incomplete.
Limited customization options (fonts/backgrounds) and navigation quirks (arrow-key controls, auto-pause).

2026-05-03	Le*****	Все працює, рекомендую. Особливо сподобався ШІ переклад на українську мову з англійської. Everything works, I recommend it. I especially liked the AI translation into Ukrainian from English.
