Quilt and Superhuman Mail

Superhuman Mail is an email client with AI features. Quilt is a personal agent that also covers messages, calendar and meeting notes. They overlap most in email.

What we say about Superhuman Mail comes from its own public pages, linked at the bottom, gathered on 2026-10-11. Products change. If something here is out of date, write to hello@joinquilt.app and we will fix it.

TopicQuiltSuperhuman Mail
What it isA personal AI agent for your mail, messages, calendar and meeting notes. You talk to it as Q. Invite-only.An email client with AI features. The company behind it, formerly Grammarly, renamed itself Superhuman. Its suite also includes Grammarly, Coda and Superhuman Go.1
Where it runsA Windows desktop app and an iPhone app. Q is on all three of its screens: Q, Inbox and Calendar. How it worksA Mac desktop app, a Chrome extension, iPhone and iPad, and Android.2
What it connects toGmail and Outlook email and calendars, plus Slack and WhatsApp chats, kept together in one Inbox and one Calendar.Gmail and Outlook accounts, with Google and Outlook calendars shown together. The Mail MCP server, on the Business plan and above, lets AI tools such as Claude and ChatGPT search, draft and send email and manage events.36
Where your data is processed and storedYour calendar, meeting notes and Q's memory are stored on your devices, with an index of your mail. When Hey Q uses a cloud model, the request goes from your device straight to Anthropic, using your own Claude key. Email text never goes to Quilt's own AI. Privacy Max turns off all cloud help, including Hey Q. Exactly what goes whereWith Ask AI on, Mail stores your emails through a third-party vendor that its help center describes as SOC 2 compliant. Ask AI queries and responses are stored. Instant Reply and Auto Summarize ones are kept for 90 days.45
Training on your dataQuilt never trains on your data. During the alpha, Q uses your own Claude key, so Anthropic's terms for API keys apply to requests made with it. Quilt's servers are not in that path. DetailsIts help center says neither Mail nor any vendor trains on your data. When you use the Mail MCP server with an outside AI tool, that tool provider's own policies apply to the data it receives.456
Acting for youA cloud model only suggests steps. Q can draft and propose, and cannot send, pay, post or delete. You press send. Inbox changes show a preview, apply when you tap, and can be undone.Auto Drafts write a reply for you to edit and send. Through the Mail MCP server, an outside AI tool can search, draft and send email. Superhuman says the send tool can send emails instantly and advises turning on confirmation in your AI app. Whether it asks first is a setting in that AI app, not in Superhuman Mail.67
Meeting notesYes, on Windows. Q listens on your computer and nothing joins the call. It asks before each meeting, and gives you summary, decisions and to-dos afterward. How it worksWe did not find a meeting notes feature in the AI feature list of Superhuman Mail.5
AvailabilityInvite-only for now, on Windows and iPhone. Free during the alpha.Paid plans for each team member, called Starter and Business, plus an Enterprise plan you arrange with its sales team. Ask AI, Auto Drafts and the Mail MCP need the Business plan or above.468

Where Superhuman Mail fits well

  • Your team shares conversations and comments on email.
  • You use a Mac or an Android phone. Quilt does not run on them yet.

Where Quilt fits well

  • You want one agent across mail, chat, calendar and meeting notes.
  • You want your calendar, meeting notes and Q's memory kept on your own devices.
  • You want every send or change to wait for your OK.

What Quilt cannot do yet. It is new, invite-only and runs on Windows and iPhone only, with no Mac, Android or web app. It has no team or shared-inbox features and it connects to fewer outside services than most products on these pages. During the alpha, bring your own Claude key.
