躍問 (Yuewen)
StepFun's free Chinese chat assistant on the Step model series
Part of this entry was LLM-drafted and is being polished.
Yuewen (躍問) is StepFun (階躍星辰)'s consumer chat product. StepFun is a notable mainland LLM startup with a research focus on multimodal — Yuewen reflects that with strong image / document parsing, OCR-grade table reading, and reasonable Chinese writing. The web app and Android / iOS apps are free, no waitlist, no VPN.
Editor's verdict
Yuewen punches above its weight on multimodal — give it a screenshot of a Chinese government PDF or a complex table, it parses cleanly. Pure-text reasoning is mid-tier (StepFun keeps the strong stuff in their API tier). Useful as a free supplement when you need to dump images / files at a Chinese-first model; not a daily-driver replacement for GLM or DeepSeek.
