01 / What people ask AI to do
Conversations extend beyond paid work.
In the May 2026 Claude chat and Cowork sample, 43.36% of classified conversations were work-related, 40.20% personal and 16.45% coursework. These are conversation shares from one provider, not population adoption rates.
Purpose of Claude conversations
Global chat and Cowork sample, May 2026; 0–100%.
Exact values and populations
| Measure / group | Share | Observation period | Population |
|---|---|---|---|
| Work | 43.36% | May2026 | Global sampled Claude chat/Cowork conversations in calendar May2026 |
| Personal | 40.2% | May2026 | Global sampled Claude chat/Cowork conversations in calendar May2026 |

02 / The resulting artefacts
Answers, documents and guidance are common outputs.
The output analysis covers 10 April–10 June 2026. Explanations or answers, documents or reports, and guidance are selected categories, not the complete output distribution.
Three common outputs
Chat and Cowork, 10 April–10 June 2026; 0–100%.
Exact values and populations
| Measure / group | Share | Observation period | Population |
|---|---|---|---|
| Explanations / answers | 17% | 10Apr–10Jun2026 | Sampled Claude chat/Cowork conversations |
| Documents / reports | 15% | 10Apr–10Jun2026 | Sampled Claude chat/Cowork conversations |
| Guidance | 11% | 10Apr–10Jun2026 | Sampled Claude chat/Cowork conversations |
03 / Outputs within each purpose
The same output can serve different purposes.
Documents and reports appear in 20% of work conversations, 21% of coursework conversations and 6% of personal conversations. Each row has its own conversation base; the three values are not parts of one total.
The same output, different purposes
Share producing a document/report within each purpose category; 0–100%.
Exact values and populations
| Measure / group | Share | Observation period | Population |
|---|---|---|---|
| Work conversations | 20% | 10Apr–10Jun2026 | Conversations within the indicated purpose category |
| Coursework conversations | 21% | 10Apr–10Jun2026 | Conversations within the indicated purpose category |
| Personal conversations | 6% | 10Apr–10Jun2026 | Conversations within the indicated purpose category |
Outputs are not outcomes: a generated document does not establish its accuracy, adoption or value. Conversation shares also differ from the share of people using AI.
Anthropic Economic Index: Cadences, 26 June 2026. Automated, privacy-preserving classification; consumer Free/Pro/Max chat and Cowork. These panels exclude Claude Code and API traffic. The report and monthly dataset use different observation windows.
04 / Science & research
Research changes task by task.
A separate Anthropic study follows research workflows. Analysis and writing account for the largest session shares; gathering data and generating hypotheses account for less.
Session shares, not adoption rates. This consumer sample describes use within Claude, not the share of scientists using AI, time saved or better research. Ideation may be hidden inside other tasks.
Research activity by task
Weighted shares of core-research sessions · 2 August–30 September 2026
Every bar uses the same 0–100% scale. Interfaces have separate session bases.
