In short
A TikTok video generator AI produces short vertical videos formatted for the TikTok feed without an editor. Vidup takes a script, blog post, or product URL, writes and voices an AI voiceover, burns in bold synced captions, matches stock footage clip by clip, and adds a music bed, then exports a 9:16 video ready to upload. The same pass also produces Reels and Shorts formats, so one script covers every short-video platform, all on a flat plan with no per-video credits.
Creators and brands who want a steady stream of TikTok posts without editing skills.
Captions that hold attention
Vidup burns in bold, word-timed captions so your video reads clearly on mute, which is how most of TikTok watches.
Idea to post in one pass
A short script or a URL becomes a finished vertical video, no clips to source, no timeline, no manual sync.
One video, every platform
The same TikTok also exports as a Reel and a YouTube Short, so you post everywhere from a single script.

The questions buyers ask before they pick a video tool, answered straight.
How do I make TikTok videos without filming?
Give Vidup a script, a blog post, or a product URL and it builds the video for you. You get an AI voiceover, bold burned in captions, matched stock footage, and music in a 9:16 file ready to upload. No camera, no clips to source, no editing.
What aspect ratio does TikTok use?
TikTok is vertical 9:16, full screen on a phone. Vidup composes for that ratio from the first frame at 1080p, so captions and footage are built for vertical rather than cropped down from a widescreen clip. The same pass also exports 1:1 and 16:9 versions.
How many TikToks can I make on the $19 plan?
Starter at $19 a month (or $15 a month billed yearly) covers about 15 to 20 videos, which is roughly a post every other day. Growth at $39 a month suits daily posting. Nothing is metered per render, so you are not buying credits on top.
Do the captions sync with the voiceover automatically?
Yes. Vidup times the captions to the AI voiceover it generates and burns them into the video, so nothing drifts and there is nothing to sync by hand. That matters on TikTok, where a lot of the audience watches with the sound off.
Can I add my own music or a trending sound?
Vidup includes a licensed background music bed with every video, mixed under the AI voiceover. It does not pull trending sounds from TikTok, since those are licensed inside the app. If you want a trending audio, you can add it on top at upload time in TikTok itself.
Can a brand use this for TikTok without a creator on camera?
Yes. Vidup never puts a person on screen, so the brand voice comes through narration, captions, and footage instead of a presenter. That keeps posting going when nobody on the team wants to be on camera and when hiring a creator is not in the budget.
