Startup insights
Value proposition

Watch any foreign-language video in your own language — real-time translated subtitles plus AI dubbing that plays in sync with the original.

Problem solved

Language barriers block access to foreign content: news, tutorials, anime, lectures. Manual subtitle translation is slow and reading while watching kills the experience — InstDub makes any video instantly watchable in your language.
