Eva

This is a Chinese-language content creation system built for social media creators working on platforms like Xiaohongshu, Douyin, and Weshipin. It's not a simple content generator. Instead, it walks you through the actual production chain: clarifying messy ideas, identifying your audience, validating headlines against real viral patterns, and only then writing scripts. The commercial brief parser is interesting because it extracts brand constraints into a separate card before touching any content, preventing that common problem where brand requirements leak into headlines that sound like ads. It also extracts and stores your voice patterns and persona memories so outputs can match how you actually write. The routing is verbose but deliberate, with hard gates that prevent jumping straight to draft creation without validated inputs.
