About 思畅 AI
Sichang AI is a private AI creation space for Chinese-language creators, operated by Predicate LLC. It covers five creation lines—AI chat, roleplay, image generation, video, and audio—all sharing one account and one credit balance. According to the official website, chat lets you freely switch among a dozen-plus Chinese-language models; roleplay supports importing character cards and building custom personas and lorebooks; image generation covers photorealistic, anime, and photo-editing fusion styles; video supports text-to-video, image-to-video, reference-image-to-video, extension, and editing; and audio can produce finished clips with multi-character dialogue, emotion, and soundtrack. Conversations are stored under your account; the official site states they are not used to train any model, not sold to advertisers, and not used for content profiling, and you can export all your data or delete your account and all content with one click. No client installation is needed—just open it in a browser; phones, tablets, and computers share the same account with real-time sync. Developers can call the chat, image, and video models via API; text chat is compatible with OpenAI and Anthropic interfaces and can be plugged into agents such as Claude Code.
