## Review summary

Subadub is handy for language learning: it adds readable subtitles you can copy, paste, and export as .srt, works alongside Netflix subs, and includes a useful S keyboard toggle. It’s actively maintained. However, it suffers from reliability issues, overlapping/subtitle placement problems, and a lack of customization (e.g., no remember-settings, movable/resizeable text). Language availability can be inconsistent, and occasional bugs require workarounds like refreshing or switching episodes.

### Pros

- Enhances language learning by letting you view, copy-paste translations from subtitles, and export them as .srt for offline study.
- Displays subtitles alongside Netflix's own subs and can be set to be readable with a large font and a black box, with easy selection and download options.
- Useful keyboard shortcut (S) to quickly turn subtitles on and off for study sessions.
- Saves subtitles easily as files, enabling offline review and practice.
- Maintains compatibility with Netflix UI updates and receives quick fixes/updates when issues arise.

### Cons

- Frequent instability and bugs: it stops working or fails to load subtitles, especially after Netflix UI changes.
- Subtitles often overlap with Netflix subtitles and cannot be moved or resized, causing readability and visibility issues.
- Lacks essential customization and remember-settings feature; resets or defaults on new episodes or idle time, plus inability to adjust size, color, or position.
- Inconsistent language availability, with some languages disappearing or being unavailable in certain contexts or regions (e.g., Japanese options missing).
- Occasional load/bug issues that require refreshing or switching episodes, and some UI elements may not display in fullscreen.
