FAQ
Answers before you install.
The essential workflow, support, trial, and privacy limits stay visible before you add the extension.
Does this extension translate videos in real time?
Real-time or near real-time translation is the goal, so translated subtitles can appear while supported video or audio keeps playing.
Does it work with YouTube?
Langvue is built for browser-based video workflows, including YouTube-style pages. Some websites may still limit audio capture or extension access.
Does it support live streams?
Yes, live sessions are one of the main use cases. Translation speed can vary with audio quality, browser permissions, and stream behavior.
Does it support audio-only pages?
Yes. Langvue is designed for both online video and audio pages, including podcasts and browser-based audio content where access is allowed.
Do I need to upload the video?
No manual video upload is required. The extension is designed to work directly in the browser while supported media plays.
Is my audio stored?
Audio is processed to provide transcription and translation. The product is designed around clear browser permissions and avoiding unrelated browsing-history collection.
