Original short videos, produced and published on schedule.

Shortmith is a publishing tool run by a single operator. It produces original vertical videos — factual explainers and product clips — and publishes them to YouTube Shorts and TikTok accounts the operator owns. It does not repost anyone else's videos and has no public sign-up.

How it works

01 · PRODUCE
A new video, made for one topic Each video is built from scratch: a script written for it, narration, licensed stock imagery and captions timed to the voice.
02 · REVIEW
Held until it is ready Every video is checked before it goes out. Channels can require the operator to approve each video by hand.
03 · CONNECT
The operator's own accounts The operator links their YouTube and TikTok accounts once, through the platforms' official sign-in (Google OAuth, TikTok Login Kit).
04 · PUBLISH
Posted at the channel's time Videos are uploaded with the official YouTube Data API and TikTok Content Posting API, once a day per channel.
