What they do

These assistants draft replies, triage incoming messages by priority, and can auto-categorize or route email based on content — reducing time spent on repetitive correspondence.

How they work

They typically learn from a user's past writing style and prior replies to similar messages, so drafts increasingly match the user's own tone rather than reading as generic.

Where they fit

Most valuable for high-volume, routine correspondence; anything sensitive, high-stakes, or relationship-critical still warrants a human-authored reply.
