Translate Video Subtitles With a Fast, Convenient AI Agent Workflow

Free with daily credits

Sign up for free, then claim your daily credits each day. Those credits cover your translations and AI dubbing, so regular use stays free—no credit card needed to start.

Free AI dubbing

Need more than text? Switch to the Media tab, pick an AI voice, and download a dubbed video file. Most free subtitle tools can't do this at all.

90+ languages

From English↔Spanish to long-tail pairs the small tools skip. Many competitors stop at 15–30 languages; we go further.

Save SRT or TXT

Export as TXT, SRT, XLSX, or DOCX. XLSX is rare among subtitle translators: it drops your translated lines into a spreadsheet your editor can filter, review, or reuse as a translation memory.

Speaker identification

When you upload a video, we automatically label different speakers in the transcript, so you always know who said what.

Context-aware AI

Translates each line in context, not word-by-word like pasting into a general translator (which breaks timecodes).

Why Translate Subtitles Online

Video subtitle translation used to mean pasting lines into a machine translator one by one, then fixing every broken timecode by hand. Today an online video subtitle translator does the work in minutes—keeping your timestamps intact and your formatting clean. Whether you're localizing YouTube captions, preparing course videos for international students, or dubbing a short film, the right tool should be free to use, fast, and accurate across the languages your audience actually speaks. That's what we built: a translator that takes your video and returns translated subtitles the way creators actually work.
