What can an AI email assistant actually do?

It drafts replies and new messages from a short prompt, summarizes long threads, writes cold outreach and follow-ups, and can auto-sort or prioritize your inbox. You stay in control by reviewing each draft before it sends.

How is it different from Gmail's built-in Smart Reply?

Smart Reply offers a few canned short phrases, while an AI email assistant writes full, context-aware messages in your own tone and can handle outreach, summaries, and inbox triage. It also learns your style from past emails rather than picking from fixed suggestions.

Is it safe to give an email assistant access to my inbox?

These tools request broad mailbox access, so check whether the provider trains on your emails, stores message content, and offers encryption or a no-retention option. For sensitive accounts, prefer assistants with clear data policies and read exactly what OAuth scopes you grant.

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.
