In short
A YouTube Shorts maker AI creates short vertical videos ready for the Shorts feed without manual editing. Vidup takes your script, blog post, or product URL, generates an AI voiceover, burns in captions timed to the audio, pulls matched stock footage, and adds a music bed, then exports a 9:16 short built for YouTube. Because it also exports 1:1 and 16:9 in the same pass, the same idea becomes a Reel, a TikTok, and a long-form clip, all on a flat plan with no credits.
Creators and channels who want to post daily Shorts without editing each one by hand.
Built for 9:16
Vidup composes for vertical from the start, captions and footage framed for the Shorts feed rather than cropped from a wide video.
Ship one a day
A blog post or a few lines of script becomes a finished short in one pass, so a daily posting habit stops being a full-time job.
Reuse the same short
Every Short also exports as a Reel, a TikTok, and a 16:9 clip, so one script covers your whole posting schedule.

The questions buyers ask before they pick a video tool, answered straight.
How do I make YouTube Shorts without editing?
Paste your script or a blog post and Vidup returns a finished 9:16 Short. It narrates the copy with an AI voiceover, burns in captions timed to the audio, matches stock footage to each line, and adds music. You upload the file straight to YouTube.
What resolution and aspect ratio should a YouTube Short be?
YouTube Shorts are vertical 9:16 and can run up to three minutes. Vidup composes for 9:16 from the start at 1080p, so captions and footage are framed for the vertical player rather than cropped down from a widescreen edit. The same pass also exports 16:9 for a standard upload.
Can I turn a long YouTube video into Shorts with AI?
Not from the video file itself. Vidup builds from text, so paste the script, the transcript, or the blog post behind the video and it produces a fresh Short with new voiceover, captions, and footage rather than a clipped excerpt of your original.
Do I need a separate tool for Shorts, TikTok, and Reels?
No. Vidup exports 9:16, 1:1, and 16:9 in the same pass, so a Short is also ready for TikTok, Reels, and a standard YouTube upload. One script covers the whole schedule, and you are not paying for a second tool to resize anything.
Are AI generated Shorts allowed on YouTube?
Yes, YouTube allows AI assisted content, and it asks creators to disclose realistic synthetic content in the upload settings. Vidup videos use an AI voiceover over licensed stock footage, not synthetic people or events, but you should always follow YouTube's current disclosure and originality rules.
Can I edit the script or voiceover before the Short exports?
Yes, you control the words going in. Vidup builds the video from the script you paste, so tweak the copy before you generate and the voiceover and captions follow it exactly. What you do not get is a timeline, keyframes, or clip level editing after the fact.
