7 min readAI caption generator: burn-in captions matched to your voiceover
AI caption generator for YouTube Shorts and TikTok — auto captions timed to narration, not just Instagram text. Honest ZeroEdit pricing.
An AI caption generator for video burns readable text onto Shorts timed to speech. Instagram caption-copy tools are a different job. ZeroEdit on zeroedit.ai pairs captions with VO and B-roll. Not zeroedit.me.
Caption-copy vs burn-in captions
- Social caption copy — post description text for Instagram/TikTok
- On-video captions — timed burn-in for silent autoplay
