Animated captions for TikTok, Reels and Shorts
Most people watch short videos without sound. SubSpark adds big animated captions that pop, fill or highlight word by word, in styles made for vertical video.
Viral styles
TikTok, Hormozi, Neon and more: pick a style and see it on your video at once.
Word-by-word animation
Every word is timed from the speech, so highlights land exactly when the word is spoken.
Vertical ready
Works with any aspect ratio. Your logo and your own saved styles are included.
- Upload your vertical video
- Choose a caption style and colors
- Export the video with burned-in captions
Will the video have a watermark?
No. The free plan has no watermark.
Can I use my own font and colors?
Yes. Six fonts, custom colors, size, position and animation speed.
How long does export take?
Export runs in your browser, and on modern browsers it is faster than the video length.
