China's Top AI Chatbots in 2026: Kimi vs Doubao vs Qwen vs Ernie vs ChatGLM — Pick in 3 Minutes

Picture this: you need to write a Xiaohongshu post tonight, translate a long English email into natural Chinese, turn a pile of messy Excel rows into a clean table, or just check whether your new medicine can be taken with coffee. You open your browser, type "AI chatbot", and five Chinese products show up — Kimi, Doubao, Qwen, Ernie Bot, Zhipu ChatGLM. They all look similar. Which one do you actually open? This guide gets you to the right answer in about three minutes.

The one-line summary up front

Short version: they all chat for free, they're all polite, and they'll get the basics right. The differences only show up on longer, harder, or more specific tasks. Below, one short section per assistant — what it is, what it's actually good at, what it costs, and where it falls short.

Kimi — the long-document reader

Kimi is built by Moonshot AI, and its signature trick is handling very long text. Upload a 200-page PDF, a whole novel, or a folder of meeting notes, and it will summarise, quote, and answer questions across all of it. This is what people mean by "long-context" — just think of it as "can read a whole book at once". Best for: students with long papers, lawyers reviewing contracts, anyone drowning in PDFs. The free tier covers normal use; membership starts around ¥49/month, with the exact tiers on the official site. Weak spot: for quick everyday chat it is not noticeably friendlier than the others, and AI image generation is not its focus.

Doubao (豆包) — the friendly everyday one from ByteDance

Doubao is ByteDance's assistant, and it feels like it: fast, casual, and tightly linked to Douyin and Jianying (CapCut's Chinese cousin). It's the best pick if you want to chat, brainstorm a caption, or generate an image without switching apps. The free tier is genuinely generous. In mid-2026 ByteDance launched a paid "Pro" tier starting around ¥68/month for people who burn through the expert-mode quota — most casual users never need it. Weak spot: serious long-document work and deep reasoning are not its headline strengths.

Qwen (通义千问) — the office worker

Qwen is Alibaba's model. In everyday chat it is solid, but its edge is office work: document drafting, table cleanup, meeting transcription notes, and it connects with Alibaba's cloud and DingTalk. If your pain point is "turn this raw transcript into minutes" or "fix this spreadsheet", Qwen's office tools are purpose-built for that. The chat side stays free; the heavier office-assistant membership starts around ¥19/month. Weak spot: as a pure fun-chat companion it feels a bit more corporate than Doubao.

Ernie Bot (文心一言) — the one that browses Baidu for you

Ernie is Baidu's assistant. Its signature move is search: ask it something current or factual, and it pulls from Baidu results and shows you the sources, which is handy for "is this news true" or "what's the latest on X". Since 2025 Baidu has kept Ernie completely free — yes, it even refunded earlier paid members — so price is not a reason to avoid it. Weak spot: compared to Kimi on long PDFs and Qwen on office tooling, it is more of a generalist, and its custom-agent ecosystem is smaller.

Zhipu ChatGLM (智谱清言) — the brainy one from Tsinghua

Zhipu spun out of Tsinghua University. Its ChatGLM model leans on hard reasoning: math, code, logic puzzles, and tricky multi-step questions. It is also the home of AutoGLM, the phone-using agent that taps your screen to book a train or fill a form — genuinely impressive when it works. A free tier exists; paid VIP starts around ¥79/month. Weak spot: for pure casual writing it is less polished than Doubao, and the fancy phone-agent features are still hit-or-miss.

Two honorable mentions

Tencent Yuanbao keeps the WeChat/QQ social graph in mind and is fully free; DeepSeek is famous for open-source-style deep reasoning at zero cost, and many people keep it as a second opinion. Both deserve a spot on your phone's home screen.

The 30-second comparison table

Which one should you actually open?

• Writing a Chinese social post (Xiaohongshu, WeChat): Doubao — it is tuned for casual, emoji-friendly Chinese
• Translating an English email: any of them work; Ernie or Qwen are solid, and Kimi handles long threads best
• Office documents, spreadsheets, meeting minutes: Qwen
• Reading a 100-page PDF or thesis: Kimi
• Free choice for students on a budget: Ernie (fully free) or Doubao's free tier
• Hard math, code, logic: Zhipu ChatGLM (or DeepSeek as a free second opinion)
