Captionate is an AI subtitle generator and editor for video and audio. Generate accurate subtitles, refine wording and segment boundaries, translate naturally, and export subtitle files or a captioned video in one workflow.
Upload once, then generate, refine, translate, style, and export without rebuilding your caption timeline.
Add a video or audio file, optionally choose a time range or provide context, and let Captionate automatically detect the spoken language and create editable, time-aligned subtitles with word-level timing.
Correct individual words, split or merge subtitle segments, guide AI translation with custom instructions, and preview subtitle styling in the editor.
Download the open subtitle version as SRT, VTT, ASS, or TXT, or render styled subtitles directly into an MP4 video.
