Vertical 1080×1920 clips with captions, ready for Shorts, Reels and TikTok.
Everything a clip needs
Follows the speaker
Face tracking keeps the person centred in the vertical frame, panning smoothly when they move.
Word-by-word captions
Each word lights up as it's spoken. Bold, Clean or Neon — or switch captions off.
Built for every script
Devanagari, Bengali, Tamil, Arabic and Urdu right-to-left, Thai, Chinese and more — shaped correctly.
Hook scores
Every clip gets a 1–10 score for how likely it is to stop the scroll. Best first.
Quick editor
Trim to the word, change the title and caption style, or speed it up from 0.25× to 2×.
Translated captions
Speak Hindi, caption in English — or any of 50+ languages (Artist and Pro).
