Is Utau - Learn Languages with Youtube safe?

Enhances YouTube transcripts for language learning with sentence replay, furigana, text sizing, and speed controls.

This extension makes YouTube transcript controls easier to use, including prominent transcript access, single-sentence playback that stops at sentence completion, and adjustable transcript text size. It supports furigana for Japanese transcripts and can automatically select a preferred transcript language such as Japanese or English when available. Settings let users auto-open transcripts on video load and choose default transcript behavior.
