Choosing an AI assistant in China in 2026 is different from choosing one in the global market. International tools (ChatGPT, Claude) need VPN access and are less optimized for Chinese language. Chinese tools (DeepSeek, Kimi, 豆包, 通义千问) are free, locally accessible, and natively understand Chinese.
The smart strategy in China is a two-tool approach: one Chinese chatbot for daily Chinese tasks, one international chatbot for English and specialized tasks.
