Does TikTok use AI? What picks the feed, and the rules for AI videos
Two questions hide in this one: whether a machine decides who sees your video, and what happens when the video itself was made with AI. TikTok answers both on its own help pages, checked on 21 October 2026, and this guide puts the answers in the order a creator needs them.
Yes. TikTok uses recommender systems to choose what each person sees: they treat a viewer's interactions as signals, predict how likely that viewer is to be interested in each eligible video, and rank by the prediction. The main inputs are user interactions, content information and user information, and TikTok says their weight can change over time.
TikTok also builds generative AI into the app and labels AI-generated content. For creators that means three rules from the same help pages: realistic AI images, audio or video must be labelled; turning the label on does not affect distribution unless the post breaks the Community Guidelines; and Creator Rewards pays only for original content you made yourself.

How does TikTok’s AI decide what you see?
On a new account, TikTok may ask for interest categories such as pets or travel. Skip that and the feed starts with recent posts that are popular with others, shaped by location and language settings. From the first swipe on, every like, share, comment, full watch and skip becomes a signal.
Each recommender picks from a large pool of eligible videos and orders them by predicted interest. Some also borrow from people with overlapping tastes, and TikTok's help page gives a worked example of it.
The example from TikTok’s help page on how it recommends content, drawn as a grid. Two viewers share three likes, so the system may predict the rest of one viewer’s likes for the other. It is one way a video reaches people who do not follow the account that posted it.
Two more rules from the same page shape a feed. TikTok tries to diversify it with creators a viewer has not seen, so some videos will look unrelated to their interests, and it typically does not recommend a video the viewer has already watched. The controls for steering or resetting your own feed are in the guide to the TikTok FYP.
What does the For You prediction read from your video?
What TikTok lists as shaping the For You feed
Factor
What TikTok names
What a creator controls
User interactions
Likes, shares, comments, watching in full or skipping, accounts of followers you follow back
Whether the opening earns the next second, and whether the video is worth sending
Content information
Sounds, hashtags, number of views, the country it was posted in
The sound and the tags; the rest follows from the first two rows
User information
Device settings, language, location, time zone and day, device type
Nothing directly; it is the viewer’s side
For most users, TikTok says, interactions weigh more than the other two, and they may include time spent watching. Follower count is not on the For You list; TikTok names it for the LIVE feed and for account suggestions. That is why a new account with no followers can still reach strangers, and why the first seconds matter more than the profile. The platform comparison sets this list beside what Instagram and YouTube publish.
Search is the exception. For search results TikTok weighs content information most, including how well the video matches the words typed, which is the case for putting the searched phrase in the caption and on screen covered on the TikTok SEO page.
Do you have to label AI-generated videos on TikTok?
TikTok defines AI-generated content as images, video or audio generated or modified by AI, from a cartoon style to a realistic face. Whether a label is required depends on what the AI did.
TikTok’s labelling rules for AI-generated content
What the post contains
Label
Realistic AI-generated images, audio or video
Required by the Community Guidelines
Content completely generated or significantly edited by AI, such as a person shown saying or doing something they did not, or a face swap
Encouraged; required as well if it looks real
AI used only for minor corrections or enhancements
Not counted as significantly edited
Made only with TikTok’s own AI effects
TikTok labels it automatically
Uploaded with C2PA Content Credentials attached
TikTok may label it automatically; the label cannot be removed
To label a video yourself, tap Add post, record or upload, tap Next, then turn on the AI-generated content setting under More options. The post shows “creator labeled as AI-generated”. A caption line or a hashtag sticker also counts as disclosure. Putting the label on footage that was not altered breaks TikTok's Terms of Service.
Does an AI label reduce views on TikTok?
Not according to TikTok. Its help page says that turning on the AI-generated content setting “won't affect the distribution of your video as long as it doesn't violate our Community Guidelines.” The risk runs the other way: realistic AI content posted without a label may be removed.
Some AI content is not allowed even with a label: fake authoritative sources or crisis events, public figures shown being bullied, endorsing or being endorsed, the likeness of anyone under 18, and the likeness of an adult private figure used without permission. A post with any of these has no reach to protect.
Can AI-generated TikToks make money?
TikTok's Creator Rewards page does not mention AI at all. What it sets is an originality test: content “designed, filmed, and produced by you”, at least one minute long, that shows your expertise, talent or creativity. It then lists what does not count as original, and several items describe common AI channel formats: looping videos, single or multiple photos, text-overlay-only content, and compilations of material from other sources without new ideas.
So the honest answer is that TikTok has not said how it treats AI-assisted videos under the program. A video you script, record and edit, with AI used along the way, fits the published test the same way any video does. A slideshow of generated images with a voice-over sits close to two named exclusions. The Creator Rewards guide covers the rest of the eligibility list and the earnings calculator.
Which AI tools are built into TikTok?
TikTok's help center describes these features as AI-powered. Two are limited to adults, and TikTok says AI Cast may not be available to everyone.
AI Alive turns a photo into a short video from a text prompt, for Stories. TikTok says a video takes about a minute to generate and drafts expire after 7 days.
AI Image generates and edits images in a chat, for people 18 and over. A posted image carries a link that shows an AI-written summary of the prompts used.
AI Cast generates or remixes videos starring you and friends who have authorised their own “AI Self”, also 18 and over, and not available to everyone.
Filter Keywords on the viewer side can use AI to hide synonyms and variations of a word you have filtered out.
All four make or sort content inside TikTok. None tells you, before posting, whether the opening of your own video will hold a stranger, which is the job the recommender judges you on.
Where Go Viral fits
Go Viral is an AI video analyzer that reads your clip before it is posted, not a video generator and not connected to your TikTok account. It returns a hook score for the first three seconds, a view forecast given as a range, and a retention heat map that marks where viewers are likely to leave. Those map onto the first row of the table above: the interactions TikTok weighs most are decided by whether people keep watching.
TikTok and AI questions
Is the TikTok algorithm AI?
▼
TikTok calls it a set of recommender systems. Each one ranks eligible videos by its prediction of how likely a viewer is to be interested, learned from that viewer’s likes, shares, comments, full watches and skips. TikTok keeps the word AI for features such as AI Alive and AI Image, and for the option that filters similar keywords.
How do I turn on the AI-generated label on TikTok?
▼
Before posting a video: tap Add post, record or upload, tap Next, open More options and turn on the AI-generated content setting. For a photo, the same setting is under Post settings. The post then reads “creator labeled as AI-generated”.
Can TikTok tell if a video was made with AI?
▼
In some cases. TikTok says it may label a post automatically when the creator used TikTok’s own AI effects, or when the upload carries Content Credentials, the C2PA metadata some AI tools attach. An automatic label cannot be removed. For everything else TikTok asks the creator to label and lets viewers report unlabelled posts.
Will TikTok remove my AI video?
▼
Only if it breaks the rules. TikTok says it may remove unlabelled realistic AI content, and it does not allow some AI content even with a label: fake authoritative sources or crisis events, public figures shown being bullied or endorsing something, the likeness of anyone under 18, and adult private figures used without permission.
Know what the recommender will see first
Import the clip, read the hook score for the first three seconds and the heat map for the middle, and post the cut more people are likely to finish.
