90.6% of AI Users Manually Edit Output, 13.0% See Increased Overtime | Survey on Business AI Usage Released

Knit Co., Ltd. (Headquarters: Shibuya, Tokyo; CEO: Takao Akizawa), operator of the online outsourcing service 'HELP YOU,' has released a survey on 'AI Usage in Business Scenes' targeting 600 business professionals aged 25–59. The survey highlights a gap between expectations of efficiency and the reality on the ground (March 2026, N=600).

### Key Survey Findings - AI usage in business remains at 46.2%. - 90.6% of AI users manually refine the outputs. - 13.0% of users experienced increased overtime after introducing AI. - 91.3% feel the importance of 'human-centric value.'

### Survey Results Detail #### Adoption Rate Only 46.2% of respondents use AI for work, while 53.8% do not. However, 13.5% are heavy users who spend more than an hour a day with AI, showing a clear polarization between non-users and daily users.

#### Top Tools ChatGPT is overwhelmingly the most popular tool at 40.4%, followed by Gemini (24.6%) and Copilot (19.9%). This suggests that standard tools for business are becoming established.

#### Usage Areas The most common uses were 'Email/Document Creation' (48.0%), 'Adjusting Tone/Suggesting Paraphrases' (41.2%), and 'Meeting Minutes/Summarization' (30.7%). AI is primarily used as a tool for 'drafting' rather than completing tasks.

#### The Efficiency Gap While 49.5% felt AI reduced their working hours, 13.0% saw an increase in overtime. The top reason for increased overtime (66.7%) was 'the need to refine AI output to a usable business standard,' followed by 'the newly generated process of verifying accuracy' (41.7%). AI is creating new tasks like 'check and correction' while reducing others.
