01
Folders you define, in plain English
Tell Zerrow what belongs in each folder — receipts from Stripe, cold sales pitches, calendar invites from clients. The AI handles the rest. No filter rules, no regex.
Mission directive · eliminate inbox clutter
An inbox that sorts itself.
Zerrow reads every new email and files it into the folders you actually use — newsletters, invoices, cold pitches, calendar invites. The only thing left in your inbox is what deserves your attention.

Features
Built for people who'd rather not live in their inbox.
Every part of Zerrow is calibrated to one objective: keep the inbox at zero without making you babysit it.
02
Real-time sorting as mail arrives
Zerrow listens to Gmail's push events. New mail is read, summarized, and moved within seconds — long before you open the app.
03
One-sentence AI summaries
Every email gets a single-line summary so you can scan the day in a minute. Open only the ones that need a real reply.
04
Learns from your moves
Drag an email into a different folder and Zerrow updates that folder's profile. The next misclassification of the same kind doesn't happen.
05
Reanalyze on demand
Added a new folder? Reanalyze any email and Zerrow reroutes it against your latest rules — no full re-sync required.
06
Suggested replies, when you want them
Zerrow drafts a concise, on-tone reply for any thread. You stay in control — review, edit, and send from the same view.
How it works
Three steps to inbox zero. Then it keeps itself there.
Sign on, describe your folders, hand over the controls. Zerrow takes it from there.
01
Connect Gmail
Sign in with Google. Zerrow connects to your existing Gmail account using OAuth — no password, no migration.
02
Describe your folders
Create a folder and write a one-line rule in plain English. Zerrow learns the rest from a handful of examples.
03
Open a clean inbox
Newsletters land in Newsletters. Receipts land in Receipts. Your inbox shows what's left — the email that actually wants you.
FAQ
Questions, answered.
Everything you need to know before you hand Zerrow the keys to your inbox.
Does Zerrow store my emails?
Zerrow syncs message metadata and content so it can classify and summarize. Everything is scoped to your account, and you can disconnect Gmail at any time from Settings.
Will it move emails in Gmail itself?
Yes — when Zerrow files an email into a folder, it applies the matching Gmail label so your phone, web, and other clients stay in sync.
What if it gets it wrong?
Move the email to the correct folder and Zerrow learns from it. The next time a similar email arrives, it routes correctly. You can also hit Reanalyze on any single message.
Which mail providers are supported?
Gmail and Google Workspace today. Other providers may come later.
