Email triage questions, answered
What is Cerno AI?
Cerno AI, also written Cerno or Cerno Email, is an AI email assistant for business inbox triage available at cerno.email. It reads every message that arrives, sorts it into a category, writes a one-line summary, scores how urgent it is, and drafts a reply you can send in a couple of taps.
What is email triage?
Email triage is the process of quickly sorting incoming mail by importance so you answer what matters first. Cerno AI does the sorting for you, grouping messages into categories such as clients, transactions and promotions, and flagging the ones that need a reply.
How does an AI email assistant work?
Every message that arrives is read by the assistant, summarized in one or two lines, assigned a category and a priority, and placed in the right folder. You get a short digest instead of a wall of unread mail, plus suggested replies you can send in a couple of taps.
Is Cerno AI secure?
Your mail is stored in an encrypted database and only you can read it. Sign-in supports passkeys, an authenticator app and one-time recovery codes, and you can delete your account and all associated data at any time from Settings.
Does it work with Gmail and Outlook?
Yes. You get a personal Cerno AI forwarding address, and you point a Gmail, Outlook or custom-domain rule at it. Anything you forward is triaged automatically, so you can start with a single label before moving your whole inbox across.
