Right now, Add Subtitle offers four core capabilities: Add Subtitles, Video Translation, Rewrite & Dub, and Add Voiceover. Each feature supports different creation scenarios—helping you complete a full video localization workflow at a lower cost, from subtitles to multilingual versions to consistent audio.

1) Add Subtitles

Add Subtitle supports real-time automatic subtitle generation with precise timeline alignment. It also provides multiple subtitle styles for creators to choose from—turning subtitle creation from “endless revisions” into “done in one click,” and significantly reducing the effort of subtitle editing and layout.

2) Video Translation

With Add Subtitle, you can generate multilingual versions of your video in real time. While preserving the original voice texture as much as possible, it completes language conversion—making it easier for viewers to watch and understand your content across languages.

3) Rewrite & Dub

Add Subtitle lets you finely edit your subtitle script while generating new dubbing at the same time. It also works to keep lip movement as consistent as possible—so you can rewrite your message without sacrificing natural visuals, giving creators more freedom to explore and express ideas.

4) Add Voiceover

Add Subtitle intelligently synthesizes AI voiceovers and supports realistic voice cloning. You can clone voices detected from your video assets, or record your own voice to create a custom voiceprint. By unifying voiceover style and tone, your video audio becomes more consistent—and sounds more polished and professional.
