In recent years, many AI tools have emerged worldwide beyond ChatGPT and DeepSeek.
When choosing a tool mainly for text generation, ChatGPT is often the most reliable starting point.
It excels at producing high-quality, natural writing, summaries, and business ideas—making it highly versatile for everyday business use.
For China-related information, market research, and analysis, DeepSeek is an essential AI tool.
It excels at Chinese content generation, data organization, as well as task-specific data collection and code generation, making it a valuable assistant for business in the Chinese market.
Moreover, DeepSeek integrates with search engines like Baidu, enhancing its convenience for daily operations in China.
Here, we compare the features and performance of each AI tool’s free plan.

It’s not about choosing just one tool. A practical approach is to narrow it down to two tools, such as ChatGPT and DeepSeek, and use them according to purpose.
However, introducing too many AI tools indiscriminately can increase management overhead and operational complexity, reducing efficiency.
From the perspective of account control and information security, it’s best to limit business AI tools to the minimum necessary.
Generative AI tools have become indispensable in daily business, supporting efficiency, research, and planning.
ChatGPT excels at natural language generation and offers reliable performance across a wide range of tasks.
DeepSeek, on the other hand, specializes in China-related research, analysis, and Chinese-language data organization, making it essential for business in China.
Using both ChatGPT and DeepSeek effectively can enhance information accuracy and overall work efficiency.
