Sort mail.

Sort mail. is a detailed work activity in O*NET — a concrete unit of work shared across 16 occupations and seen in 18 occupation-specific tasks. It rolls up into the broader work activity Sort materials or products. in Processing Information .

Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.

AI exposure

Of the 18 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 9 (50%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).

The Anthropic Economic Index observes real AI use on 2 of these tasks, with a mean mapped-usage share of 0.003% per task.

Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.
