AI Reels & Shorts Maker
Make vertical Reels and Shorts with AI
Short-form video wins attention — but making it is slow. Nox AI generates vertical 9:16 video from a prompt, reframes your landscape clips for Reels and Shorts, burns in auto-captions for muted feeds, and lets you drop a music track on top. Assemble a finished, ready-to-post MP4 in minutes.
Built for 9:16
Generate native vertical video, or AI-reframe any 16:9 clip to 9:16 for Reels and Shorts.
Auto-captions
Burn styled subtitles into your video automatically — most social video is watched on mute.
One-click assembly
Combine video, background music and captions into a single finished MP4.

Does it add captions?
Yes. Auto-captions transcribe your video and burn styled subtitles straight onto the clip.
Can I add music?
You can generate a track with AI or upload your own, then mix it in with the Assemble Ad tool.
