AI UGC videos are TikTok posts made with AI in the phone-shot, first-person style of user-generated content, so a brand can test many hooks without hiring a creator for each one. Relay (relaystudio.ai) makes them for your brand as slideshows and videos, then sends each post you approve to your own TikTok inbox on its day. Plans start at $49 a month ($25 for the first month) as of October 2026, and on the Scale plan ($249 a month) some of your approved drafts can go to Relay’s network of 50,000 creators, who post them from their own accounts.
Key takeaways
- AI UGC is a testing tool: the Starter plan makes 40 posts a month and sends 20 of them to your TikTok, about $1.23 per post made.
- Relay makes slideshows (TikTok photo posts) and videos built on formats getting views in your niche, written in your brand’s voice.
- Nothing goes out unless you approve it, or switch on Autopilot to approve for you. When you post a draft with realistic AI imagery in TikTok, you turn on its AI-generated content setting.
- On the Scale plan, creators can post your approved drafts from their own accounts, within the same 150 posts a month.
- Relay’s managed service makes hundreds of UGC ads from its creator network at about $5 a creative.
Why do brands use UGC-style posts on TikTok?
Because TikTok’s own ad guidance says to. Its creative best practices recommend “a DIY or not overly polished style” so ads fit in with the user-generated content around them, and suggest featuring people such as “creators, employees, or customers.”
TikTok’s data points the same way. Its analysis found creator ads drove a 70% higher click-through rate than non-creator ads at the same CPM, and ads posted to a creator’s account had a 59% higher engagement rate and a 16% higher six-second view-through rate than those that weren’t (TikTok for Business, November 2025, based on TikTok internal data from 2024 and 2025). Those numbers come from ads, not organic posts, but the lesson carries over: posts that look like a person made them fit the feed.
The problem is supply. Briefing creators one at a time is slow, and you pay before you know which angle works. AI UGC handles the testing side, so the money you spend on people goes to angles that have already earned views.
How do you test AI UGC angles on TikTok with Relay?
Make many versions at a low cost per post, post them, and let views show which hooks work. Here is how that works in Relay:
- Paste your website or App Store link. Relay learns what you sell, who it is for and how you sound, then asks a few one-tap questions. There is no brief to write, and it works for apps as well as ecommerce brands.
- Approve a spread of hooks, not one idea twenty times. Relay makes a month of slideshows and videos built on formats getting views in your niche. Swipe right on 4 or 5 different angles: a problem-first hook, a list (“3 signs you need…”), a before and after, a myth, a strong opinion. Edit the words before you approve if you want to test a specific opening line.
- Connect your TikTok once. Relay spreads your approved posts across the month and sends each one to your TikTok inbox on its day, where you add any finishing touches and tap Post. On Starter, 20 posts a month is enough to run 5 angles four times each.
- Read views after a week. Every post’s views sit in one place, so you can compare hooks side by side as the numbers come in.
- Double down on the winner. When a post does well, Relay makes new takes of it. The winning angle is the one worth handing to creators or turning into ads.
AI UGC, creator UGC or UGC ads: which do you need?
Each one does a different job, and they work well in sequence: test angles with AI, then put people behind the winners. AI UGC vs creator UGC goes deeper on when each one wins.
| You want to… | Use | Relay option |
|---|---|---|
| Find which hooks and formats work at a low cost per post | AI UGC on your own account | Starter or Growth plan |
| Have creators post your approved drafts from their own accounts | Creator UGC | Scale plan with the creator network |
| Feed paid campaigns with fresh UGC ads | UGC ads made at volume | Managed UGC ads |
Do AI UGC videos need a label on TikTok?
Often, yes. TikTok’s Community Guidelines require clear disclosure of content that uses AI or significant edits to show realistic-looking people or scenes, and TikTok says turning on its AI-generated content setting won’t affect how widely your video is shown as long as it follows the Community Guidelines (TikTok Creator Academy).
Relay does not turn on TikTok’s AI-generated content label or the content disclosure for you. When you post the draft in TikTok, turn on the AI-generated content setting if the post uses realistic AI imagery, and the content disclosure toggle where it applies. You also choose there who can see it, whether comments are on and whether duet and stitch are allowed.
Creator posts carry their own disclosure duty. The FTC tells influencers to “disclose when you have any financial, employment, personal, or family relationship with a brand” (FTC, Disclosures 101). The full platform rules are in TikTok’s rules for AI-generated content.
How much does AI UGC cost with Relay?
As of October 2026:
| Plan | First month | Then | Posts made / month | Sent to your TikTok / month |
|---|---|---|---|---|
| Starter | $25 | $49/mo | 40 | 20 |
| Growth | $45 | $99/mo | 120 | 60 |
| Scale (creator network included once paid, not on the trial) | $149 | $249/mo | 300 | Up to 150, shared with the creator network |
On Starter, $49 for 40 posts works out to about $1.23 per post made, or $2.45 for each of the 20 sent. Growth includes up to 3 people and Scale up to 5. Annual billing gives 2 months free. Checkout is $0 today on a 1-day trial (card required) that becomes your paid first month unless you cancel before it ends. See pricing for the details.
UGC ads made by Relay’s team come through the managed service at about $5 a creative. It makes the ad creative, while your media buyer or agency runs the ad account. It offers a free 15-minute call, and 5 UGC ads are on Relay.
Who is behind Relay?
Relay has generated over one billion views. It is part of Kinetic, which has launched 10 apps since March 2025 with organic TikTok as its main growth driver.
When is an AI ad tool a better fit than Relay?
If you want an ad tool rather than an organic TikTok pipeline, one of these will suit you better (each checked on the vendor’s own site, October 2026):
| If you need… | Better choice | Why |
|---|---|---|
| A scripted spokesperson ad with an AI actor | Arcads | A library of 1,000+ AI actors, ready-made ad presets built for performance marketers and translation into more than 30 languages |
| AI avatar ads plus a library of proven formats | MakeUGC | Write your script, pick an avatar, generate video, with 1000+ AI actors, 50+ languages and hundreds of high-performing videos filtered by niche |
| Ad variations launched straight into ad accounts | Creatify | Turns a URL into video ads and connects to your ad accounts so you can push ads live |
| Instagram Reels, YouTube Shorts or LinkedIn as well as TikTok | Fastlane | Publishes to all four, offers 1,000+ AI UGC characters and has a free plan |
A few limits to know before you start. Relay’s self-serve product works with TikTok only. The creator network is included only on Scale ($249 a month), so creator posts are not a small-budget option. Self-serve plans do not manage ad spend: the managed service makes UGC ad creative, and a media buyer or agency runs the account. And Relay does not guarantee views on any plan.
