Caption Generator

AdCreate's AI Caption Generator transcribes spoken audio and automatically generates perfectly timed captions and subtitles for any video. Using advanced speech recognition that supports 40+ languages, the tool delivers 95%+ transcription accuracy with precise word-level timing — producing captions that are ready to publish with minimal editing. In an era where 85% of social media videos are watched without sound, captions are not optional — they are essential for reaching your audience.

The generator goes beyond basic transcription with multiple caption styling options. Choose from animated word-by-word highlights (the viral TikTok/Reels style), traditional subtitle bars, karaoke-style color wipes, and professional broadcast formats. Customize fonts, colors, positioning, background opacity, and animation timing to match your brand. The animated caption styles that dominate short-form video — where individual words pop, scale, or color-change in sync with speech — are generated automatically without any manual keyframing.

For content creators and marketers, the real value is workflow efficiency. Upload a video, receive accurate captions in seconds, make any needed corrections in the built-in editor, choose your style, and export. You can burn the captions directly into the video for social media, or export as SRT or VTT subtitle files for YouTube, Vimeo, or web players that support closed captions. The tool also works on videos created with AdCreate's other features — generate a video with Veo 3.1, add an AI voiceover, then auto-generate matching captions, all without leaving the platform.
