E-commerce copywriting is the "assembly-line work" of the writing world: it prioritizes conversion over literary flair, and relevance over uniqueness. Product detail pages have their own sales pitch formulas; Xiaohongshu has its "sisters, listen to me" vibe; live streams have their "3-2-1, link up!" cadence. Each platform has its own grammar, requiring a full rewrite for every new listing, with demand multiplying several times over during major promotions. This highly standardized + massively repetitive type of writing is precisely the labor that AI should take over. Xi Yu is a specialized machine designed for this assembly line, and its origins are interesting: under Meitu—the company behind Meitu Xiuxiu, which dominates e-commerce "images"—Xi Yu takes on e-commerce "text," completing the full set of e-commerce content production with both legs standing firm.
What is Xi Yu?
Xi Yu (xiling.meitu.com) is an AI marketing copywriting tool under Meitu, verticalized for e-commerce and marketing scenarios: product detail copy, promotional event copy, Xiaohongshu seeding posts, live stream scripts, and title optimization. Every genre of writing that e-commerce operators deal with daily has been turned into a "fill-in-the-blanks, click-to-generate" templated assembly line. The target user profile is precise: e-commerce operators, Xiaohongshu bloggers, live streaming teams, and small-to-medium merchants without dedicated copywriters.
Core Features
Product Detail Copy
Primary scenario: Input the product name, core selling points, and target audience to generate structurally complete detail page copy—the standard narrative skeleton of an e-commerce detail page automatically takes shape: selling point extraction, scenario-based descriptions, pain points and solutions, functional details, and differentiation emphasis.
Supports platform-specific styling: The atmospheric vibe of Taobao, the parameter-heavy style of JD.com, the concise directness of Pinduoduo—the repetitive labor of "saying it in plain language for each platform for the same product" is compressed into switching a single option.
Promotional Event Copy
The demand for copy during major promotions explodes in pulses (during Double 11, one operator might need to produce dozens of sets of promotional materials). Xi Yu’s promotional templates are designed precisely for this peak: theme copy, limited-time offer scripts, countdown urgency prompts, and "clear yet enticing" expressions of discount rules—turning the late-night copywriting overtime before a big sale into batch template generation plus manual quality control.
Xiaohongshu Seeding Copy
Xiaohongshu’s writing style is somewhat esoteric: it requires authenticity over ad-speak, colloquialism, emoji rhythm, and the immersive feel of "organic word-of-mouth." This platform grammar is pre-built into templates: image-text notes, unboxing experiences, review insights, and hashtag suggestions are produced with one click. For brand accounts and bloggers who need to post seeding content daily, this is a capacity-building feature.
Live Streaming Sales Scripts
Live streaming is an abyss of spoken-word copy: opening greetings, product pitches, urgency prompts for orders, and interaction guides—Xi Yu’s generated script templates give hosts a "something to read" foundation, acting as a lifeline for new hosts and a draft-enhancement tool for experienced ones.
Title and Keyword Optimization
The engineering of search traffic entry points: balancing keyword placement with attractiveness in product titles, the basic skill of platform search exposure, with AI generating multiple options for A/B testing.
Comparison with Similar Tools
vs. General AI (ChatGPT/Kimi): Large models are not weak at writing copy, but each time you have to organize prompts and describe platform styles yourself. Xi Yu has pre-built the "stylistic grammar" of various e-commerce platforms into buttons—for operators who don’t know how to prompt-engineer AI, templates are efficiency. For experienced users who can write good prompts, general models + self-built template libraries are also a viable alternative route.
vs. Biling AI/GIISO: General-purpose writing tools have broader templates (workplace, academic, media); Xi Yu onlydeep cultivation (deeply cultivates) the single line of e-commerce marketing, and its vertical focus is its differentiator—if your main business is e-commerce, choose vertical; if needs are diverse, choose general-purpose.
vs. Alimama’s AI Copy: Taobao’s official tool is more deeply bound to platform data and the advertising ecosystem, giving Taobao merchants a home-field advantage; Xi Yu is platform-neutral, making it smoother for merchants operating across multiple platforms (Taobao + Douyin + Xiaohongshu).
vs. Meitu Ecosystem Siblings: Meitu Design Studio handles product images, Xi Yu handles copy—Meitu provides the "image-text dual workstation" for e-commerce content production, offering synergy benefits for users within its ecosystem.
Who Should Use Xi Yu?
E-commerce Operators: The daily copy production line for detail pages, events, and titles; an AI-drafted + manually injected real-selling-points assembly line that directly doubles capacity—the core audience.
Xiaohongshu Brand Accounts and Bloggers: High-frequency update pressure for seeding content, with platform-specific template supply matching their needs perfectly.
Live Streaming Teams: Batch demand for script preparation, serving as an ammunition depot for hosts and floor controllers.
Small-to-Medium Merchants and Individual Sellers: Small businesses that can’t afford to hire copywriters; one-click generation is the lowest-cost solution of "something is better than nothing"—the copywriting needs of this demographic shouldn’t be solved by human labor in the first place.
Usage Boundaries
The ceiling of AI copy is "competent generic expression": your product’s real selling points, data, and user feedback must be manually injected; otherwise, the output will be "correct nonsense" that applies to any similar product—conversion relies on specifics, and specifics rely on you.
Platforms are tighteningreview (review) of AI-mass-produced content (especially Xiaohongshu limiting reach for ad-speak and homogenized notes); the bonus period for pure template production is closing—AI provides the draft, humans provide the soul; this division of labor holds true for e-commerce copy as well.
Content with strong brand tone (brand stories, emotional marketing) remains the territory of human copywriters; clarify the tool’s positioning: it takes over the assembly line, not the creative department.
Pricing
Offers a free usage quota, with paid plans unlocking more generation counts and advanced features; refer to the official website for specifics. Compared to the unit price of an outsourced copywriter or half a day’s work of an operator, merchants with continuous needs hardly need to calculate whether this is worth it.
Whether Xi Yu deserves a spot in your toolset costs only five minutes to test: plug in the key points of a product you’re currently selling, generate a version of detail page copy and one Xiaohongshu note—if its output reaches the level of "editable for immediate use," you’ve found a new home for your weekly copywriting hours.
