Two Ways to Go Vertical — Pick What Fits Your Workflow

Create New

Start From a Prompt

Have an idea but no footage? Type it out and Steve AI generates a brand-new vertical video with script, visuals, voiceover, and captions, all sized for 9:16 from the start. No reformatting needed because it's built vertical.

Convert Existing

Reframe What You Have

Already shot in landscape or square? Upload it and Steve AI automatically reframes to 9:16, keeping the subject centered and in focus whether that's a face, a product, or on-screen text.

Generate Vertical Videos from a Prompt

Skip the blank timeline. Type your idea and Steve AI builds a complete 9:16 video with visuals, captions, music, and voiceover, sized and formatted for mobile screens from the very first frame.

Convert Any Video to Vertical in One Click

Already have a horizontal or square video? Drop it into Steve AI and reframe it to 9:16 instantly. Our AI detects the key subjects like faces, action, text and keeps it in frame, so nothing important gets cropped out. No manual dragging, no guesswork.

AI That Knows What to Keep in Frame

Manual cropping means hours of dragging, zooming, and second-guessing and still cutting someone's head off mid-sentence. Steve AI's smart reframing detects the focal point of every scene, a speaker's face, a product demo, on-screen text and automatically keeps it centered as the frame shifts from landscape to portrait.

Works on talking-head videos, product demos, gameplay footage, and text-heavy content alike. Switch between 9:16, 1:1, and 16:9 without re-editing your video from scratch.

No Idea Is Too Big
