✓ Pros

• Ghostwriter — Unlike generic AI writers that produce corporate-sounding text, Ghostwriter trains on your actual sent emails. It learns your vocabulary, sentence structure, sign-offs, and even your tendency to use (or avoid) exclamation points. After a week of use, drafts are consistently close enough to your natural writing that most need only minor edits
• Natural language search — "What did Sarah say about the Q3 budget last month?" returns the exact email. No boolean operators, no advanced search syntax. This alone saves significant time for anyone with a large email archive
• AI thread summaries — Long email chains get automatically condensed to key decisions, action items, and outstanding questions. Summaries update in real time as new replies arrive
