How AI email assistants work
The assistant connects to your mailbox and feeds the thread, your instruction, and often past emails into a large language model. The model generates a draft in the requested tone, which you review and edit before sending. Tools that manage your inbox add classification and rules on top, tagging and sorting messages as they arrive.
