Duet Mail

The writer watches how you actually compose mail and builds drafts that sound like you, not like a generic assistant. You can take a draft as is, tweak a line or rewrite the whole thing before it sends. This is the feature that carries the product, because the value only shows up if the output reads as your own writing.

Any long chain can be reduced to a short read of the main points and decisions. Attachments are covered too, so a packed PDF doesn't force a full read before you can respond. It's the fastest way to catch up on a thread you were copied into late.

Duet Mail sorts incoming mail into categories and pushes the messages that matter to the top. The point isn't tidiness for its own sake; it's that you open the inbox and see what needs you first, rather than working top to bottom through whatever arrived last.

A chat-style assistant sits beside your inbox. You can ask it to find an email, draft a reply, organize a set of messages or answer a question about something buried in your mail. It searches your email and connected calendar, so questions like "when am I free" get a grounded answer.

The assistant watches for messages you sent that got no reply and for tasks tied to a thread, then brings them back when they matter. Nothing here is exotic, but a quiet follow-up you forgot is exactly the email that costs a deal, so the feature earns its place.

Connecting a calendar lets you schedule and manage events from inside the inbox. It also feeds context into drafts, so when you propose a meeting the assistant can lean on the times you're actually free instead of leaving the slot vague.

Duet Mail runs on both Gmail (including Google Workspace) and Microsoft Outlook, and it works inside the inbox rather than in a separate tab. For a mixed team this matters: people don't have to change providers to use the same assistant.
