questions

Free video captioner FAQ

Is this video captioner really free?

Your first video is free and has no watermark. After that, videos cost from 7.5¢ each and you only pay when you want more. There is no subscription.

Do I need to sign up?

Not to start. Upload your video and pick a style first. When you click Generate video, you make a free account with Google or email, and your video is made straight away.

How do I add animated captions to a video?

Upload the video on this page, choose a caption style, and click Generate video. Caption Plug writes the captions from the speech, times every word, and gives you an MP4 to download.

What is an animated subtitle generator?

It turns speech into captions that move word by word, like the pop-up captions on TikTok, Instagram Reels and YouTube Shorts, instead of plain lines of text at the bottom of the screen.

Does it work on my phone?

Yes. It runs in the browser on iPhone and Android, so there is no app to install. Keep the tab open while your video renders.

Will my video have a watermark?

No. Every video you download is clean, including the free one.

How long can my video be?

Up to 60 seconds, which fits TikTok, Reels and Shorts. Trim longer videos first.

Can I fix a wrong word?

Yes. After your video is made, open Words, fix any word, and download it again for free.

Is my video uploaded?

No. Your video stays on your device and is rendered in your browser. Only the audio is sent, so the captions can be written.
