About Asteroids — AI email assistant
Asteroids is an AI email assistant that works right inside Gmail. It sorts your inbox, writes replies that sound like you, and follows up so nothing slips.
WHAT IT DOES
• Smart bundles — mail is sorted into bundles you control (Customers, Sales, Teammates, Notifications, Newsletters…) with their own plain-English rules, and labelled in Gmail.
• Drafts in your voice — Asteroids learns how you write from your sent mail and drafts replies you can edit and send.
• Goals — tell a bundle what you want ("get a demo booked", "answer billing questions from our docs") and Asteroids works toward it, including calendar invites once the other person confirms a time.
• Knowledge docs — attach pricing sheets, FAQs or policies to a bundle so replies cite the right facts.
• Unsubscribe suggestions — see the mailing lists you never read and leave them in one click (you click the sender's own unsubscribe link; Asteroids never does it for you).
• Daily briefing — a short summary email from your own account to you: what needs a reply and what Asteroids handled.
• Activity with undo — every action Asteroids takes is listed, with one-click undo where possible.
YOU STAY IN CONTROL
Every bundle starts in draft-only mode: Asteroids never sends, forwards or deletes anything until you switch that bundle to Auto. Trashed mail stays recoverable for 30 days and is never taken from threads you replied to or starred.
HOW TO START
1. Install the extension and open Gmail.
2. Click "Sign in to Asteroids" next to the Google apps button and approve access.
3. Click "Asteroids" in Gmail to open your dashboard.
