What Is a TikTok Story?
TikTok Stories are 24-hour posts that vanish automatically. No manual cleanup required.
24-hour ephemeral content format
Stories disappear after 24 hours. That makes them low-stakes and high-frequency. Ideal for quick promos, limited-time offers, or testing new creative.
Visibility across profile, inbox, and feeds
Per TikTok's Help Center, your Story surfaces on your profile, in your followers' inboxes, and may appear in For You and Following feeds. That's broad reach for a temporary post.
Engagement and reply mechanics
Viewers can react and reply directly. Replies land in your inbox as DMs. Fast feedback, no comment thread to manage.

How to Create an AI-Generated TikTok Story
The creation and upload steps are separate. An AI tool builds the visual. TikTok handles the publish.
Generate AI images or video with a creation tool
Use a dedicated AI creative platform. Feed it a product URL, brand colors, or a text prompt. Get a polished 9:16 visual in seconds. No design skills needed.
Ensure dimensions match 1080 × 1920 (9:16 aspect ratio)
TikTok's standard vertical format is 9:16. The recommended resolution is 1080 × 1920 px, consistent with TikTok's documented video ad specifications. Uploading the wrong ratio means TikTok auto-crops your creative. You lose control of the composition.
Upload to TikTok via Story creation flow
Once your file is ready, follow the step-by-step flow below.

Labeling Your AI-Generated Story: Required Steps
This step is not optional. TikTok enforces it.
Why TikTok requires AI disclosure
TikTok's Community Guidelines require a label on any content with realistic AI-generated images, audio, or video. The requirement applies to Stories, too.
How to apply the creator label
Before posting, toggle the AI-generated content setting on the post settings screen. That applies the creator label to your Story.
When auto-labels apply automatically
TikTok can detect AI content via Content Credentials (C2PA metadata). If your AI tool embeds that metadata, TikTok may label the content automatically. Manual labeling is still the safest default if you're unsure whether your file carries that data.
What happens if you don't label
Unlabeled realistic AI content violates TikTok's Community Guidelines. TikTok can remove the post. Repeated violations affect your account standing. Label every time.
---
What You Can't Do: AI Content Restrictions
Some AI content is banned outright. No label makes it acceptable.
Prohibited: deepfakes, fake crises, and false endorsements
TikTok prohibits AI-generated content that depicts fake crisis or emergency events, creates false endorsements from public figures, uses unlicensed likenesses of private figures or minors, or impersonates real people in misleading ways.
Impact on reach and removal risk
Prohibited AI content gets removed. Misleadingly labeling unaltered content as AI-generated also violates Terms of Service. Both outcomes damage your account standing. Stick to original, clearly labeled creative.

How to Optimize Your AI Story: Size, Format, and Quality
Right specs prevent cropping, rejection, and quality loss.
Recommended dimensions and aspect ratio
1080 × 1920 px at 9:16. TikTok's video ad specifications confirm 9:16 vertical as the standard format. Stories follow the same convention.
File format and size limits
TikTok accepts MP4 and MOV for video Stories. Keep file size under 500 MB to stay within TikTok's documented limits for video content.
When to resize before uploading
If your AI tool exports square or landscape images, resize before uploading. Do it before you open TikTok. Once you're in the Story flow, you lose cropping precision.

Frequently Asked Questions
Do I have to label AI-generated TikTok Stories?
Yes. TikTok's Community Guidelines require a label on any AI-generated content with realistic images, audio, or video. Toggle the AI-generated content setting before posting. Skipping it can result in content removal or account penalties.
What size should an AI-generated TikTok Story be?
Use 1080 × 1920 px at a 9:16 aspect ratio. That matches TikTok's standard vertical format. Export as MP4 or MOV and keep the file under 500 MB.
Can I use AI-generated images of real people in TikTok Stories?
Not without restrictions. TikTok prohibits deepfakes, false endorsements by public figures, and unlicensed likenesses of private figures or minors. Violating these rules results in content removal, regardless of whether you applied the AI label.
Does Coinis publish directly to TikTok?
Not yet. Direct TikTok publishing is on the Coinis roadmap. Today, Coinis generates and resizes your Story creative, then you upload it manually to TikTok's Story flow. Coinis publishes directly to Facebook and Instagram.
