## Overview

Chiefy, previously launched as Duet Mail, positions itself as an AI chief of staff for your inbox. It connects to Gmail, Google Workspace or Microsoft Outlook and immediately starts sorting incoming mail into smart categories, so you can see at a glance what needs action, what is merely informational and what can wait. Promotional messages, newsletters and statements are filtered away from the things that actually require you.

Its drafting engine is the core of the product. Chiefy learns how you write and then produces replies that match your tone, knows your calendar availability and draws on memory of past conversations so the draft is context-aware. Instead of staring at a blank reply box, you review, tweak if needed and send in seconds. It also generates instant summaries of long threads and attachments, extracting key points, decisions and action items.

An embedded AI assistant takes this further: you can ask it in natural language to find a specific invoice, locate emails from a given sender or find a slot for a meeting, and it searches your mailbox and calendar to answer. Smart reminders surface follow-ups automatically so nothing slips through. The product emphasizes security, using OAuth 2.0, field-level encryption before storage, least-privilege API access and Google's annual CASA security assessment.
