How it works
Three steps to a quiet inbox.
No new app to learn — Nimbus sits on top of the email you already use.
1
Connect your inbox
Securely link Gmail or Outlook in two clicks. Nimbus reads only what it needs and never sees your password.
2
Nimbus gets to work
It triages every thread, summarizes the long ones, and drafts replies in your voice — quietly, in the background.
3
You skim and send
Open to a calm, ranked inbox. Approve a draft with one tap, tweak a word, or let the auto-handled noise stay gone.
Why Nimbus
Email, finally on your side.
Everything Nimbus does runs quietly in the background, so the work is done before you even open the tab.
Drafts in your voice
Nimbus learns how you write and prepares replies you can send in a tap — or rewrite in a sentence.
Draft ready
Smart summaries
A 40-message thread collapses into a two-line digest. Catch up in seconds, not scrolls.
Private by design
Your mail is encrypted end-to-end. Models run on your data — never on someone else's training set.
Follow-up autopilot
Nimbus watches the threads that went quiet and nudges you before a ball gets dropped.
Works where you do
Connects to Gmail and Outlook in two clicks. Your folders, labels, and signatures stay exactly where they are.

Trusted by early teams
Early users are getting their evenings back.
“I closed my inbox at 6pm for the first time in two years. Nimbus triaged 300 messages overnight and the eight that actually needed me were waiting at the top, already drafted.”
“Drafts that actually sound like me. I just skim, tweak a word, and send.”
“It quietly killed three Slack channels worth of follow-ups. I didn't even notice.”
“Our support queue used to bleed into the weekend. Now Nimbus handles the routine replies and flags the rest. Saturdays are mine again.”
“The morning digest is the only email I read before coffee now. Everything else can wait — and Nimbus already knows that.”
Questions
Everything you might be wondering.
We're opening the private beta in waves, with public launch targeted for September 1, 2026. Waitlist members get in first — the countdown on this page tracks it live.
Yes. Mail is encrypted in transit and at rest, models run on your data alone (never a shared training set), and we store only what the waitlist needs. The Security page has the full details.
Pricing isn't final, but everyone who joins from the waitlist locks in founder pricing for life — a meaningful discount over the eventual public plans.
Gmail and Outlook at launch, with Fastmail, Proton Mail, and iCloud Mail close behind. Connecting takes two clicks and keeps your existing folders and labels untouched.
Every signup gets a referral link. Invite three friends who join and you jump 1,000 places — keep inviting and you keep climbing. Your live position is on your confirmation card.
Anytime. Reply to any email from us, or reach out to support, and we'll remove your record completely — no questions asked.
