Free AI chatbot developed by StepFun...
Step AI takes a multimodal all-rounder approach among Chinese AI chatbots. Image recognition handles landmarks, car models, and animal species with precision, while document parsing processes contracts, reports, and academic papers. The AI Creative Board launched in 2025 is a highlight — users can generate apps from text descriptions without coding. StepFun also open-sourced the Step-Video-T2V video generation model and Step-Audio voice model, showing full-stack multimodal ambitions. The product is entirely free, with less commercialization pressure than peers. Best suited for personal users needing a multimodal AI assistant, and entrepreneurs/product managers wanting to validate ideas with zero-code app generation.
Step AI (formerly Yuwen) is a free AI chatbot developed by StepFun, featuring strong multimodal capabilities. It supports multi-turn dialogue, image recognition, document parsing, web content extraction, internet search, and multilingual translation. In 2025, it added the AI Creative Board for no-code app generation from text descriptions, with web and mobile apps supporting real-time sync.
