When the wave of AI image generation crashed over the industry, one of the most anxious sectors was stock photo platforms. Businesses like Qianku, Baotu, and SheTu, which built their empires on "selling images," watched helplessly as users began using AI to "create" their own visuals. However, these stock platforms actually hold two cards that pure AI companies do not: first, a massive library of clearly copyrighted training and compositional assets (the primary commercial concern with AI-generated images is precisely copyright); second, a pool of design-focused users who have already developed a habit of paying for services. By grafting AI capabilities onto these two advantages, defense transforms into offense.
Infinite Canvas is the card Qianku plays: rather than becoming "China’s Midjourney," it positions itself as an "AI-powered stock platform"—integrating generation, assets, templates, and design tools into a single hub to serve those who "don’t want art pieces, but need a poster delivered by Wednesday afternoon."
What is Infinite Canvas?
Infinite Canvas (58pic.com/aigc) is an AI image creation platform under Qianku, a long-standing domestic provider of licensed stock assets. It integrates AI text-to-image and image-to-image generation, AI design assistance (posters, covers, layout), intelligent background removal, and other capabilities, while syncing with Qianku’s library of licensed images, vectors, and PNG assets. The target user profile is clear: self-media operators, e-commerce sellers, and corporate planning/admin staff—people with high-frequency image needs, lacking professional design skills, and prioritizing copyright safety.
Core Features
AI Text-to-Image
Generate directly from Chinese descriptions, with preset styles covering realistic, illustration, anime, traditional Chinese style, poster aesthetics, and other common commercial directions. Optimized Chinese semantics mean users no longer endure the torture of "translating to English then tweaking prompts," a standard advantage for domestic platforms targeting mass users.
Its generation tone aligns with its positioning: it does not pursue the artistic impact of Midjourney, but rather the commercial practicality of being "just right for a WeChat Official Account cover or e-commerce main image"—stable styles, clear subjects, and reasonable whitespace. These "design asset" attributes are more important to the target users than artistic flair.
Image-to-Image and Style Transfer
Reference-image-driven generation, photo-to-illustration conversion, and inpainting—high-frequency workflows for content operations (creating multi-platform variants from a single asset, converting real-person photos to illustrations to avoid portrait rights issues) all have dedicated entry points.
AI Design Assistance: The Chemistry with the Asset Library
This is the core layer that distinguishes Infinite Canvas from pure generation tools:
Template + AI Poster/Cover Pipeline: Select a template, fill in text, and use AI for color palette and layout fine-tuning to produce publish-ready results in minutes—a "guaranteed output" path for design novices.
Intelligent Asset Retrieval: During the design process, AI recommends licensed assets from Qianku (icons, decorative elements, backgrounds) based on needs. AI-generated images and licensed assets can be mixed within the same canvas—"generation fills the gap where assets fall short, while assets stabilize the output of generation." This complementarity is exactly the product’s intent.
Intelligent Background Removal and Batch Capabilities
One-click background removal for transparent outputs. Batch generation and processing cater to e-commerce scenarios with multiple SKUs—toolbox-style peripheral capabilities that complete the feature set, allowing users to avoid opening separate websites for individual functions.
Comparison with Similar Products
vs Jimeng/Tongyi Wanxiang: Large-tech AI generation platforms have stronger model quality, iteration speed, and community buzz. For pure "generate a good image" needs, prioritize them. Infinite Canvas’s differentiation lies in "what happens after generation"—the finished-product pipeline of templates, assets, and layout, plus the integration of copyright resources.
vs Canva/Chuangkit: Online design platforms have more mature template ecosystems and editing experiences (Canva especially), with AI capabilities rapidly catching up. Infinite Canvas’s local advantage is its backing by Qianku’s asset library. The three are in highly homogeneous competition; actual choice often depends on: which platform’s membership you already hold, and which platform’s template style suits your taste.
vs Midjourney/SD: Professional generation tools crush competitors in quality ceiling and controllability. However, English prompts, subscription models, network barriers, and the "break in the chain where you still have to do your own layout after generation" are all deterrents for this target user group. The two categories serve almost non-overlapping audiences.
vs Buying Assets Directly: The traditional path—searching, downloading, and assembling yourself. The difference with AI is that "what you can’t find, you can create." The long-tail blind spots of asset libraries are filled by generation capabilities, which is the logical closed loop for stock platforms doing AI.
Who Should Use Infinite Canvas?
Self-Media and New Media Operators: The weekly pressure of WeChat Official Account covers, Xiaohongshu illustrations, and event banners makes the template + AI generation combination a "fast and decent" mass-production solution—the platform’s core user base.
E-commerce Sellers: Main image processing, detail page illustrations, and promotional posters. Background removal + batch processing + templates in one stream. Copyright safety is particularly critical for stores (asset infringement complaints are a real risk in e-commerce).
Corporate Admin and Planning Staff: Internal posters, notification illustrations, and PPT assets—classic scenarios where outsourcing design isn’t worth it, but you don’t know how to use Photoshop yourself.
Existing Qianku Members: For users with existing membership benefits, the AI feature is a convenient addition. Prioritize maximizing the ecosystem you’ve already paid for.
Limitations
Generation quality lags behind top-tier professional tools. Its positioning is "commercially sufficient" rather than "artistically stunning," so scenarios requiring high image quality need more professional toolchains.
The dual identity of "asset platform + AI tool" brings a mixed user experience: numerous feature entry points, and intertwined membership systems and billing methods (generation credits, asset downloads, template rights). New users need to spend some time clarifying what they are actually buying.
Commercial copyright must be verified item by item: The licensing scope for AI-generated content, assets, and templates varies across different membership tiers—a common flaw among all asset platforms. Spending ten minutes reading the terms clearly before commercial use is far cheaper than dealing with disputes afterward.
Pricing
Offers free trial credits. Generation counts, asset downloads, and premium templates are billed via recharge or membership systems; Qianku memberships include partial benefits. Refer to the official website for specifics.
Infinite Canvas is essentially a pragmatic choice: if you want "a ready-to-use finished image" rather than "an impressive generated image," this one-stop format of assets + generation + templates will likely fit your workflow better than pure generation tools. Use the free credits to run a test based on your real output needs (say, that article you need to publish next week)—whether it earns a spot in your usual toolset will be clear within half an hour.
