The year-end sales promotion has entered the sprint stage. While the vast majority of cross-border sellers are still troubled by the high costs of shooting materials and influencer marketing, an auto parts seller from China has quietly used a "non-human" content model to deliver a textbook-level sales combo.
A Christmas projection lamp priced at less than $14 sold 35,700 units in 7 days, with single product sales exceeding $500,000, and behind this explosive growth, the main account has less than 4,000 followers.
This brand, which makes people envious, is the Chineseauto parts Tuke brand—JOYTUTUS.

Understanding TikTok's "New Involution" Through a Case Study
Many sellers have questions: Why do seemingly inconspicuous accounts suddenly rush to the top of the category?
In fact, if we break down this case, we will find a cruel reality: on TikTok, the real cost has shifted from "placement" and "supply" to "the content itself".
Today on TikTok, advertising costs and influencer commissions are similarly expensive for everyone. The real gap is who can produce high-quality content faster and more consistently.
If someone can produce content at extremely low cost, with high frequency and high quality, then in the same track, he almost naturally has the advantage of dimensionality reduction attack.

So why can AI win?
Actually, it's caused by emotional value and aesthetic gap.
The core of JOYTUTUS's success lies in two points: emotional value and content efficiency.
AI videos build dreamy and warm holiday scenes at extremely low cost, projecting gorgeous lights onto the living room, courtyard, and exterior walls of houses, so that users can immediately see "what their home will look like after installation".
This kind of "what you see is what you get" scene directly satisfies all the imagination of European and American users for the holiday atmosphere, and also maximizes their emotional value.
But when followers rush in, problems also arise: using AI as well, why can others sell explosively, but it's getting harder for themselves to break out?
In fact, there are several common pitfalls hidden here:
One is aesthetic differences. Our domestic preference for products tends to favor strong contrast and information stacking, while in the eyes of European and American users, this kind of content generally appears flashy and cheap, making the content lack "texture".
Another is platform risk. Template videos that are roughly batch-generated in a short period of time and are highly homogeneous are easily identified by TikTok as low-quality or spam content, and thus directly restricted in traffic.
So the final result is: on the surface, everyone is playing with AI, but the only ones who truly benefit are those who can produce "high-quality + high-fit" content.

Key to Breaking the Deadlock: From "Blind Effort" to "Precise Attack"
If you don't want to be dragged down by content internal friction, but want to continuously produce short videos that meet overseas aesthetics and can convert, you can't do without AI tools that truly "understand Tuke".
In the industry, there are actually some good tools developed based on cutting-edge models, such as CreatOK.ai, etc. Their value is not just "saving time", but more about "doing it right".
1. Say Goodbye to "AI Plastic Feel", Align with Overseas Aesthetics
Traditional AI content is often criticized for weird lighting, fake characters, poor texture, and unrealistic atmosphere.
However, CreatOK.ai has changed this—sellers only need to upload a product image and simply enter the product selling points, and they can generate natural, delicate dynamic images and lighting effects.
On the one hand, such images hardly show obvious AI traces; on the other hand, in terms of composition, color use, and rhythm, they are more in line with the viewing habits of mainstream European and American users, and the overall video texture is no less than that of professional human teams.
More importantly, it can automatically adjust styles and presentation methods for different countries and markets. For example: the US market focuses on simplicity and directness, emphasizing results; the European market pays more attention to detail and texture.
The CreatOK.ai tool can output different versions for different sites, achieving precise matching of content and market.

2. Deconstructing Viral Content for You, No More Blind Imitation
The success of JOYTUTUS is not "just randomly shooting a few videos and going viral", but is based on a whole set of reproducible viral logic.
The pain point of ordinary sellers is: seeing other people's videos get millions of views, but can't tell what's good about them, only "vaguely feel it's good", then imitate blindly, and naturally the effect is hard to replicate.
But with CreatOK.ai, it's different. It is developed by the Echotik team based on the Sora 2 model and supports structured deconstruction of viral videos.
You only need to drop in a competitor's video link, and the tool can quickly analyze for you:
- How the hook in the first 3 seconds is designed (visuals, copy, emotional points)
- The storyboard rhythm and general shot structure of the entire video
- The style, rhythm, and coordination of the BGM with the visuals
On this basis, sellers can consciously transfer these "methodologies" to their own products, rather than simply copying, thus achieving "absorbing the logic, not just copying the shell".

Make Good Use of AI, Don't Get Bogged Down in Internal Friction During This Year-End Promotion
AI tools are bringing the cost and threshold of content production to the lowest point.
For cross-border sellers sprinting for the year-end promotion, this is actually a rare window of efficiency.
Especially at this time node of the year-end promotion, time is the biggest opportunity cost:
Rather than exhausting energy in repeatedly revising scripts, struggling with visual styles, and trying various shooting schemes, it is better to hand over mechanical and repetitive work as much as possible to AI tools (CreatOK.ai) to complete.
Sellers should really focus their energy on three things:
1. Discover the real selling points and differentiated scenarios of the product.
2. Find the emotional points and aesthetic preferences that users in the target market care about.
3. Use AI to quickly test different routes and precipitate the data into your own content methodology.
Tuke has never been about who works harder, but about who knows how to leverage better.
Make good use of this "east wind" of AI, free up time and manpower from inefficient content internal friction, and invest more in product selection, strategy, and user research, so that you have a chance to achieve real exponential growth in this year-end promotion.
