What kinds of AI videos do well on TikTok?

The AI videos that hold attention borrow a format viewers already know (a livestream, a tutorial, a storytime, a dance trend) and put a recurring, original character in it, with a clear turn in the last beat. Generic AI spectacle stitched from random clips is the weakest bet, and reused material with nothing new added is not eligible for the For You feed[1].

Six formats, with examples we made

Every row below is a video we published, with the one-line idea behind it. Open the prompt page to see the full timed prompt.

Formats from our own posting. Five of the six feature the same recurring character.
FormatWhat happensExample and prompt
Livestream storytimeShe talks to her chat from a phone propped on the table; something goes wrong; she softens at the end.Hate mail, prompt
Tutorial / how-toA beauty-tutorial structure (ingredient, step, close-up, reveal) with a twist.Love potion, prompt
Solo danceOne locked camera, a song as audio reference, a physical gag in the last beat.Look up, prompt
Group danceThree characters, one planned mistake, a caught-in-the-act ending.Pure gold, prompt
Trend recreationA known walk-up, break-away, regroup structure performed by your characters.Own it, prompt
ExplainerA stylised host explains one idea in short scenes with a voice-over.Penny, prompt

Here is the one-line idea behind the hate-mail video. A good line names one situation and the turn:

reads her hate mail live at breakfast and one letter starts screaming at her

More ideas for the talk-to-camera format are in AI livestream video ideas, and the full library is at /prompts.

What made these work, and what did not

Should AI videos have a recurring character?

Yes, for three reasons. Viewers follow characters, not prompts: a name, a face and a catchphrase are what make someone come back. The platform rules lean the same way. YouTube, for example, lists using AI to visualise an original character and narrative as allowed to monetise, and allows a series with the same characters when each episode has its own story, while it refuses videos that put characters in the same situation with the same outcome over and over[4]. And a fixed character makes production cheaper, because the reference image and description are already done; see how to keep an AI character consistent.

How often should you post?

We could not find an official TikTok posting-frequency recommendation in our sourced notes, so this is judgement, not data. Post as often as you can make each video distinct. A new situation for the same character every day beats three near-identical clips a day, both for viewers and for originality rules. Render one take per video and fix the prompt rather than generating spares; spare takes double the bill and rarely beat a better prompt.

People also ask

Are AI dance videos still worth making?
They work best with a twist the viewer did not expect (a mistake, a gag, a caught-in-the-act ending). A plain dance with nothing happening is the most copied format there is.
Do I need to label these on TikTok?
Realistic-looking ones, yes; TikTok requires the label for realistic AI content and encourages it for the rest[2].
Can I use a famous character in my AI TikToks?
We do not. Video models block famous-character looks in our experience, and only a copyright owner can authorise adaptations of a work[5]. Design an original character instead.
What is the best length?
Short enough to hold one clear turn. Most of our published videos are 30 seconds, built from 15-second clips; if you want TikTok's Creator Rewards, its videos must be at least one minute[3].
