THE PROBLEM
Miss one phrase.
Lose the whole idea.
Fast speech, unfamiliar terms, and inaccurate captions can turn a useful video into repeated rewinding. CaptionPlus keeps the spoken context visible and within reach.Read the words.
In your language.
THE EXPERIENCE
Stay with the video,
even when captions fall behind.
Choose source and target languages from the toolbar popup. Captions stay centered above the YouTube timeline while the video plays.01 · FOLLOW
A caption layer built to stay readable.
Clear, high-contrast captions remain close to the action without covering the part of the video you came to watch.
- Live words as the speaker talks
- Readable across player sizes
- YouTube captions return when you stop
02 · CHOOSE
Source in. Target out.
Open CaptionPlus from the extension bar and choose how the video should be heard and read.
- Auto detect source by default
- English target by default
- Preferences stay on your device
03 · TRANSLATE
Read the meaning without leaving the video.
Deepgram creates the source caption. Gemini translates each final phrase and replaces it directly on the video.
- Source text appears with minimal delay
- Late translations never overwrite newer words
- Source captions continue if translation fails
