Made for real work
A clear path from recording to finished work.
BriefVox turns your video into a ready-to-post captioned MP4. Choose a bold style, keep the captions in the safe zone and reuse the transcript for SRT, DOCX or AI Notes.
How BriefVox captions your video
Upload a file or paste a supported link, let BriefVox create the transcript, pick a style, then render the captioned MP4. Rendering a new style reuses the transcript instead of starting over.
Caption styles for creators
Choose from Bold Impact, Green Chip, Heavy Hitter, Karaoke Blue, Word Build, Dark Chip, Spoken Focus, Neon Pulse, Pop Color, Clean Impact, Comic Lift and Typewriter, plus 12 landscape looks. Every style can be adjusted before export.
Private by default
Source audio and video are auto-deleted after 3 days. Captioned renders are temporary, and the transcript stays available for edits and exports.
