How do I install it?

Download and unzip the package. Keep the folder containing manifest.json.

LESS SETUP, MORE UNDERSTANDING

Hear the words. See the story.

Start translation, analysis or downloads directly. No model selection or repeated “Next” steps.

Understand what is said

Reuse captions and cached results first. When captions are missing, try recognition automatically. Read original and translated speech together, with short transcript lines grouped for less scrolling.

Explore scenes and scripts

Start with a summary, then expand shot details. When there is no speech, screen text takes priority. Add your own product facts for a tailored rewrite and suggestions for new shots.

Save what you need

Export subtitles and full reports. Download readable videos individually or in a batch. The list updates for loaded videos; hover or focus to preview a cover.

KNOW WHAT HAPPENS

Every feature is free.
Data flows are clear.

Translation and full visual analysis are available without a paid unlock. If a file cannot be read, VidClara automatically tries the selected player’s media stream. Some websites can still prevent access.

Cloud processing is disclosed on first use. Translation sends captions, video or audio as needed. Visual analysis sends the full video and any product details you choose to provide to VidClara and Google.Read the privacy policy
