Recently, a relevant institution released the results of an end-to-end practical evaluation of office AI agents. The assessment covered three major dimensions—document processing, material writing, and data analysis—comprising a total of 13 secondary tasks, and evaluated eight mainstream domestic office AI agent products. The evaluation focused on the completeness of office deliverables and comprehensively assessed the participating products across five core capabilities. The results show that Doubao Work ranked first on the overall list with 85.33 points, followed by Kimi Work and WorkBuddy in second and third places, respectively. Leading products scored closely, reflecting fierce competition, while scores across the industry varied widely, showing a clear gradient overall. By category, Doubao Work led in the document processing dimension, whereas Kimi Work led in data analysis and material writing—each product demonstrating its own strengths. Notably, the data analysis dimension had the lowest average score and the most pronounced capability divergence. Data analysis and material writing are poised to become the key focus areas for office AI agent optimization and industry competition in the next stage.
