Why vibi
Stop treating sound as one block. Work it stem by stem.
Other mobile editors only touch sound as a single track. vibi splits each clip into voice, background, and per-speaker stems — keep, mute, or swap exactly what you choose.

Features
From shooting to publishing, in one hand.
No complex PC tools — it all happens on mobile. Stem separation is the spine; captions, dubbing, and AI-chat edits flow from there.
Main
Region-based stem separation
Drag a region on the timeline and split that part's voice, background, and per-speaker audio. Not the whole video — only what you need, stem by stem.
Companion
Auto captions + translation
Turn speech into captions, translated into multiple languages at once. Adjust font and position right on screen.
Companion
AI multi-language dubbing
Preserve the original voice's character while re-synthesizing it naturally in another language. Produce multiple language versions of one clip in parallel.
AI
Edit by chat
“Keep only the voice in the selected region” — natural-language commands trigger editing tools. No more digging through menus.
