Best AI Chatbots: 14 AI Assistants Compared
ChatGPT, Claude, Gemini, DeepSeek, Kimi and more side by side — what each is good at, how generous the free tier is, and whether it works from mainland China.
How to choose
- Check availability first: most Western assistants do not support mainland China, so heavy daily use there favours Chinese services.
- Pick by task: long documents → Kimi or Claude; reasoning and code → DeepSeek or ChatGPT; quick questions and voice → Doubao.
- Cross-check important answers with a second assistant — where they disagree is where you need to verify.
