Real UI: a Chinese dub playing with translated subtitles over the original player

Three steps, video never leaves its page

Every image below is a screenshot of the extension in a real Chrome on a real video page — no mockups.

Press Translate in the player

Supported video pages get a WaveShift entry point — no link copying, no new tab.

Pick language and voice in the side panel

Target language, voice cloning or standard voices, translation style — set them in Chrome's side panel and hit Translate This Video.

Progress stays on the page

Separation, transcription, dubbing, mixing — every stage shows on the player. When it's ready the button turns green.

YouTube and Bilibili, one button

Both sites share the same entry point and the same task center; Bilibili videos translate with one click too.

Permissions do exactly one job: translate and play

It's not a downloader and it never replaces the host video — it only brings WaveShift's dubbed result back into the original player. Every permission maps to something you can see.
