How it works

Socialix writes the captions
It transcribes the spoken audio and times the captions to the clip — no typing.
03
Style and render
Adjust the caption look in the editor, then render a finished, captioned 9:16 clip.
Why creators use Socialix for this
Auto-transcribed
Captions are generated from the video's audio, so you start with text instead of a blank timeline.
On-brand styling
Caption fonts and colors live in your template, so every clip matches your page.
Burned in, post-ready
Captions are rendered into the video — no separate subtitle file to upload.
