You don't need a motion designer to get captions that look like the ones on the biggest channels.

Increase Your Engagement and Reach a Wider Audience

Most feeds autoplay on mute, so an uncaptioned video is silent and easy to scroll past in the first second. Captions hold the viewers who never turn the sound on, and make talking-head clips, tutorials and podcast cuts followable for anyone watching somewhere loud or reading along instead of listening.

Customise Your Captions and Keep Every Video On-Brand

Font, colour, stroke, shadow, position, scale — every part of the caption is yours to set. Start from one of the presets and adjust it, or build a look from scratch. Keep that look consistent so a week of Shorts, Reels and TikToks all read as unmistakably yours.
