Create Instagram Reels with AI — Captions, Safe Zones, and Reel-Ready Export
Instagram Reels require 9:16 vertical video, ideally 15–90 seconds, with captions placed inside safe zones to avoid being covered by the username, audio tag, and action buttons on the right edge. Shortify applies all of these constraints automatically.
Describe your idea — a product teaser, a quick how-to, a trending topic reaction — and Shortify generates the script, adds AI voiceover, overlays captions in the Reels safe zone, and composites background visuals. The result is a polished Reel ready for upload.
How It Works
- Enter your idea. A sentence or two is plenty — Shortify builds the full script.
- Pick a style. Brainrot, storytime, explainer, or character dialogue — each shapes the tone and visual treatment.
- Customize captions and visuals. Choose fonts, colors, and background. Safe zones are handled for you.
- Preview and export. Watch the Reel, then download a 9:16 MP4 optimized for Instagram.
Instagram Reels Platform Constraints
- Aspect ratio: 9:16 vertical (1080 × 1920 px)
- Recommended length: 15–90 seconds (shorter Reels tend to loop more)
- Safe zones: Captions positioned to avoid the username bar, audio attribution, and right-side icons
- Caption placement: Center-screen within safe margins, customizable style
- Format: MP4 (H.264) for compatibility with Instagram uploads
Shortify is the fastest way to go from a rough idea to a published Instagram Reel — with captions, safe zones, and export settings handled automatically.
