How it works

Upload a product image, enter selling points, audience, price and use cases, then select a platform and content type. Batch mode processes 2–20 products, with common settings that can be overridden per item.

Platform-specific content

The same product produces a title, body and hashtags for Xiaohongshu, but a hook, script and conversion prompt for Douyin. The structures match each platform’s content format instead of reusing the same copy with minor wording changes.

Design decision: constrain unsupported claims

During development, the model sometimes invented product details, battery specifications, safety certifications or customer testimonials. Such claims can damage a manufacturer’s credibility.

Explicit prompt constraints prohibit inventing missing specifications or unverified safety promises. Filming guidance involving children must use compositions that do not show their faces.

Administration and permissions

Two password tiers distinguish regular administrators from super administrators; only the latter can lock accounts, reset keys or delete users. User details show credit balances, generation statistics and recent records. Credits are charged by content type and refunded automatically on failure.
