Doubao (ByteDance) – a social AI companion for young people
Scenario logic: Relying on the ByteDance ecosystem, it focuses on entertaining interactions.
UGC content generation: Abundant short video scripts and WeChat Moments copywriting templates;
emotional companionship: chat tone closer to Generation Z internet slang;
lightweight design: simple interface, suitable for fragmented use.
Limitations: Limited support for academic tasks and low adaptability to professional scenarios.
Kimi (Dark Side of the Moon) – a disruptor in long text processing
Technical breakthrough: Supports ultra-long context analysis of 200,000 words (industry average is about 20,000 words)
Academic research: Can parse an entire paper with one click and extract the framework;
Legal documents: 40% improvement in the efficiency of comparing contract terms and extracting risk points;
Literary creation: Optimizes the coherence of the plot of a novel.
Yuewen – a cognitive enhancement tool for decision support
Design concept: Strengthen thinking guidance rather than directly output answers, suitable for high-level cognitive scenarios
Multi-perspective analysis: Automatically generate SWOT analysis and simulate the positions of stakeholders (e.g. simulate the views of multiple parties in a policy debate);
Decision tree construction: Assist users in breaking down complex problems and generate an evaluation framework for options;
Cognitive bias detection: Identify logical fallacies in user questions, such as confirmation bias and the sunk cost trap.
Typical users: corporate strategy analysts, policy researchers and other professionals who require systematic thinking.

User scenario matching map
Based on 2,000 user research data, the optimal choices for different user groups are clearly differentiated:
1.Academic researchers
first choice: Kimi
When processing a 100-page paper, Kimi’s accuracy in extracting research gaps is 78%, far higher than ChatGPT’s 52%; the time required to generate a literature review is shortened by 65%.
2.Workplace efficiency enhancer
preferred: DeepSeek
Test results show that it has a 93% accuracy rate in suggesting Excel formulas, and the processing time is 4 times faster than manual operation;
supports comparison of multiple versions of SOP document generation.
3.Content creator
recommended combination of two tools: WenXinYiYan + DouBao
WenXinYiYan completes hot topic tracking and first draft writing (accesses data from Baijiahao’s hot list);
DouBao optimizes it into a short video script (including automatic insertion of popular memes).
4.Decision-makers
prefer: Yuewen
can generate six competitive scenarios before a strategy meeting;
crisis management simulations support quantitative analysis of public opinion sentiment.
Comprehensive experience evaluation dimensions
The CEI index (Comprehensive Experience Index, with 16 weighted indicators) was constructed to evaluate the following:
- International users prefer: ChatGPT
In non-Chinese scenarios, its code generation and interdisciplinary knowledge integration capabilities still lead competing products by 27%;
However, due to network restrictions, the domestic user experience fluctuates by 43%.
- The optimal solution for Chinese users: Wenxin Yiyan
Chinese CEI score of 8.9/10:
98% accuracy in livelihood services such as real-time bus inquiries and interpretation of medical insurance policies;
the ability to read and understand ancient Chinese texts exceeds the average level of Chinese masters.
- The king of the long text field: Kimi
When processing a 500,000-word file digitization project, its information structuring efficiency is 11 times higher than traditional NLP tools;
The missed detection rate in legal contract reviews is only 0.7%, which is better than that of a professional team of lawyers (2.1%).
Evolutionary trends and suggestions for future options
Current AI dialogue tools are showing three polarizing developments:
general-purpose base type (e.g., ChatGPT): continuously expanding the boundaries of knowledge and evolving towards an operating system-level platform;
vertical expert type (e.g., DeepSeek): deeply cultivating niche fields and deeply embedding with enterprise workflows;
Cognitive collaboration (e.g. Yuewen): reconstruct human decision-making models and provide a thinking enhancement interface.
Select strategy recommendations:
Individual users: use a combination according to the 80/20 principle (80% of needs with one main product + 20% special needs call professional tools);
enterprise users: need to assess data compliance (e.g. domestic models are preferred in the financial industry), API call costs (DeepSeek unit token cost is 37% lower than ChatGPT).
The final choice should not be based on the pursuit of “absolute optimization,” but rather on finding a balance among the three factors of functionality, ease of use, and compliance. It is recommended that tool audits be conducted on a regular basis, and the match between emerging scenario requirements and tool capabilities be assessed on a quarterly basis.
