// how to choose

Which Caption Tool Should You Use?

For short-form content — TikTok, Reels, Shorts — Submagic is the best dedicated captioning tool. The animated word-highlighting captions it produces are what go viral. Nothing else matches the style quality for short-form specifically. CapCut is second and free.

For long-form YouTube and podcasting, Descript wins. The ability to edit captions by editing text — rather than scrubbing through a timeline — is a genuine time-saver. Riverside is the better choice if you're recording the podcast in the first place, since it handles recording, transcription, and clips in one workflow.

If you already use CapCut or Kapwing for editing, don't add another tool just for captions. Both have perfectly good built-in auto-captioning. Separate captioning tools are only worth it if the style quality matters to your brand or the workflow savings justify the cost. See the long video to shorts workflow to understand how captions fit the full repurposing stack.
