Introducing CanvaSub: AI-Powered Captions That Transform Your Videos

What if adding captions to your videos took seconds instead of hours? That's exactly what CanvaSub does. Upload your video, and our AI handles the rest — transcription, timing, and beautiful animated captions, all automatically.

See the Difference

Here's a real before-and-after. Same video, same content — the only difference is CanvaSub:

Before: A raw video clip with no text — if someone is scrolling with sound off, they skip right past it.

After: The same clip with animated karaoke-style captions that highlight each word as it's spoken. Instantly more engaging, accessible, and professional.

Why Captions Matter More Than Ever

The numbers don't lie:

• 85% of social media videos are watched without sound
• Captioned videos get 40% more views on average
• 80% of viewers watch longer when captions are present
• TikTok, Instagram, and YouTube algorithms favor captioned content

If you're creating content without captions, you're leaving reach and engagement on the table.

How It Works

CanvaSub is built for speed. Here's the entire workflow:

1. Upload Your Video

Drop in any video file — MP4, MOV, WebM, you name it. We support videos up to 30 minutes depending on your plan.

2. AI Transcription

Our AI transcribes your audio with word-level timing accuracy, supporting 90+ languages including Arabic, Spanish, French, Hindi, and more. Most videos are transcribed in seconds.

3. Pick Your Style

Choose from multiple caption styles designed for social media:

• Minimal — Clean, simple text
• Karaoke — Word-by-word highlight (shown in the demo above)
• Boxed — Bold text with a background box
• And more styles added regularly

4. Export and Share

Download your captioned video and post it directly to TikTok, Instagram Reels, YouTube Shorts, or wherever your audience is.

Built for Content Creators

We built CanvaSub because we were tired of spending hours manually adding captions in video editors. Whether you're a solo creator, a podcast host, a social media manager, or a brand — you shouldn't need to be a video editor to make your content accessible and engaging.

Here's what sets CanvaSub apart:

• AI-powered accuracy — State-of-the-art speech recognition, not some basic auto-caption tool
• Multiple caption styles — Designed for the way social media actually works
• Multi-language support — 90+ languages with RTL support for Arabic and Hebrew
• Fast rendering — Get your captioned video back in seconds, not minutes
• No watermark on paid plans — your content, your brand
