An AI TikTok video generator for faceless videos.

An AI TikTok video generator turns an idea into a finished short video without filming or editing. Shortmint writes the script, makes a picture for each scene, adds a voiceover and word-by-word captions, and renders a 1080×1920 MP4 that you upload to TikTok with the caption it wrote.

Straight answer: how it gets onto TikTok

Shortmint posts to YouTube, Instagram and Facebook by itself. It doesn't post to TikTok automatically. For TikTok you download the finished video, press Copy on the TikTok caption, and the TikTok upload page opens with the caption already on your clipboard. It takes under a minute, and you stay in control of the one platform where posting by hand still matters most.

What the TikTok version gets

• The right size. 1080×1920 vertical, 30 to 40 seconds, which TikTok plays full screen.
• A caption written for TikTok. Shorter and more direct than the YouTube description, with an invitation to try the thing in the video and a few hashtags.
• Captions burned in. TikTok viewers often watch muted, so every spoken word is on screen, highlighted as it's said.
• A hook in the first second. Every script opens on an action, not on a greeting or a title card.

Making faceless TikToks that hold attention

The same rules that keep people watching a YouTube Short apply on TikTok. From the BioCurious channel's numbers: videos that gave viewers something to try during the video held them much longer than videos that only told them a fact. The best one was watched for — of its length on average. Shortmint's scripts are built on that: an action first, the result named within ten seconds, one clear explanation and an ending that loops back to the start.

Other platforms from the same video

The caption tool also reshapes the caption for X, LinkedIn, Pinterest and Snapchat Spotlight, each to its own length. The video itself can go to YouTube on a schedule and to Instagram and Facebook Reels without you touching it.
