Cut the boring bits

Every feature,
on your own PC.
One video, every format
Export the same video as 9:16, 4:5, 1:1 or 16:9. Fill the frame and choose what stays in shot, or fit it on a blurred background.
Captions in any language
Speak any of 17 languages and it's detected for you. With Pro, translate the captions into English, Spanish, Hindi, Portuguese and more: burned in, as two-language captions, or one subtitle file per language.
Add a music track
Drop in your own music, set the volume, trim it and fade it in and out. It dips by itself whenever someone speaks, so the voice always comes through.
Switch languages mid-video
Talk in Hindi, then English, then back again, and each part is captioned in its own language and script, instead of everything being forced into the first one.
Knows who's speaking
Speaker detection labels every voice in the transcript and starts a fresh caption when the speaker changes. Name them once, and give each one their own caption colour.
Your brand on every video
Add your logo, name tags and on-screen text, place them where you want them, and they're burned into the export with the captions.
Edit every word
Fix a name or a misheard word right in the transcript, and the captions follow. Missed a line? Add a caption in any gap. Save it as a project and every edit autosaves.
Vertical-safe placement
Phone videos get bigger captions, placed clear of the like, comment and share buttons. Audio files get a clean background video.
55+ caption styles, and growing
Word-by-word animated captions for TikTok, Reels and Shorts, plus hook titles for the first seconds. New styles arrive in updates. See every style on real footage.
Export and share
An MP4 with the captions burned in, SRT and VTT for YouTube and players, and a TXT transcript. With Pro, the Share step writes your caption and hashtags and opens the platform's upload page.
Private by design
Speech recognition, editing and export all run on your PC, so it works in airplane mode and your footage never leaves it. Safe for client work, lessons and anything confidential.
