AI caption generator FAQ.
What is an AI caption generator?
It's a tool that uses AI speech-to-text to listen to your video, write out everything that's said, and place each word on screen at the exact moment it's spoken. AnimateCaptions does this automatically, then renders the words as time-synced animated captions — no manual typing or syncing.
How accurate is the AI transcription?
We use Deepgram Nova-3, one of the most accurate speech-to-text models available, with word-level timestamps. Real-world speech is never perfect, so every word is editable in the browser — click to correct, hide, or adjust timing before you export.
What languages does it support?
36+ languages via Deepgram Nova-3 auto-detect, including English, Spanish, French, German, Italian, Portuguese, Russian, Hindi, Japanese, Dutch, and more. Note that captions render in the source language — we transcribe, we don't translate or dub.
Is it free?
Yes, free to start with no credit card — clips up to 2 minutes and 500 MB. Free exports include a small AnimateCaptions watermark. Paid plans from $7.99/month remove the watermark.
Will my captions have a watermark?
Free exports include a small AnimateCaptions watermark. Removing it is the main reason to upgrade — paid plans from $7.99/month export a completely clean MP4.
Are the captions burned into the video?
Yes. We render the captions directly into your video at full resolution with Remotion, so the download is a standard MP4 with captions baked in — no separate subtitle file needed, and it plays the same everywhere you upload it.
Can I control which words get highlighted?
Yes. Set the highlight colour word by word, drag each line to reposition it, and edit, hide, or retime any word. The AI gives you a fully synced first draft; you stay in control of every detail.
What video formats and sizes work?
MP4 and MOV up to 2 minutes long and 500 MB per file on the free tier. Portrait (9:16), landscape (16:9), and square (1:1) all work.
