Tasks AI is doing
The job stops short.
Fewer than 3% of tasks
No task
Share of the workers who do the task. The red block is the band above 50% and up to 70%. The study does not say how the other tasks spread out below 50%. This is how far into the job, not which task fills the chat. Bick, Blandin, Deming, and Schumacher, St. Louis Fed.
What fills the chat
These are not bars. Each one has its own denominator.
- About 40% of work-related messages on consumer ChatGPT are writing. About two thirds of all writing requests, work and non-work together, ask it to rework text the user supplied. Chatterji et al., How People Use ChatGPT, NBER w34255.
- Almost a quarter of Microsoft 365 Copilot Chat prompts, in one week of February 2026, were editing text. Looking up information and refining content were almost 60% of prompts that same week. Counts et al., AI in the Enterprise.
- 35% of Claude.ai conversations in the week of February 5 to 12, 2026, were computer and math tasks. The logs are Anthropic's. Anthropic, Economic Index.
- 37%, 32%, 32% In March of 2026, 37% of US workers said they had used AI at work to search for information, 32% to write, and 32% to generate ideas. The Census question has no time window. The same person can be in more than one, so the three shares do not add. US Census Bureau, Household Trends and Outlook Pulse Survey.

Among employees who already use AI at work, Gallup's reading is different again: writing and editing 51%, search or research 49%, general help 39%, in May of 2026. That base is users, not all workers, so it is not on the ruler. Use cases.
