What is an AI subtitle generator?

An AI subtitle generator turns spoken audio in a video into time-coded subtitle lines. With Subvideo.ai, you can generate subtitles automatically, edit them online, translate them and export them in professional formats such as SRT, VTT and ASS.

Automatic subtitle creation

Upload a video and let AI create timed subtitle lines as a starting point for your final version.

Editable subtitle timing

Correct start and end times, split or merge lines and preview subtitles directly on the video.

Real export formats

Export subtitles as SRT, VTT, ASS and other formats — or render a video with subtitles permanently embedded.

Why Subvideo.ai is more than automatic captions

Many tools create captions. Subvideo.ai focuses on the complete workflow after generation: editing, translation, styling, exporting and burned-in video output.

1Built for real subtitle files

Download common formats like SRT and VTT or use ASS when you need styling, position and subtitle appearance control.

2Edit before you publish

AI gives you speed, but you keep control over wording, timing and layout before exporting.

3Burn subtitles into video

Create hardcoded subtitle videos for social platforms where subtitles must always be visible.

4Subtitle translation and voiceover-ready workflows

Translate subtitles and use edited subtitle text as the basis for multilingual video workflows and AI voiceover.
