That works out to about 20,800 emails a year Cerno AI would read, sort and summarize for you.
Where the numbers come from
The estimate assumes a five-day working week (260 days a year) and that an AI triage assistant saves about 1.6 minutes per message it sorts, summarizes or drafts, the same assumption used on the homepage. Move the sliders and the figures recalculate instantly.
These are planning numbers, not a promise. Real results depend on how many messages need a reply, how long your threads run, and how much you rely on the assistant's drafts. If an exact figure matters to you, try the free trial on a single forwarded label and measure your own time for a week.
Calculator questions
Where do these numbers come from?
You tell us how many emails arrive per day and how long each one takes you. The time Cerno AI saves is estimated at about 1.6 minutes per message it sorts, summarizes or drafts for you, the same assumption used on the homepage.
Is this a guarantee?
No. It is a planning estimate based on typical usage, not a promise of a specific result. Your actual inbox and habits will differ, which is why every input is adjustable.
How does Cerno AI actually save the time?
Mail you forward to your Cerno AI address is read on arrival, sorted into categories, scored for priority and summarized in a line or two, so you no longer open every message to decide what matters. Suggested replies let you send an answer in a couple of taps.
What if I use Outlook or a custom domain?
Cerno AI works by forwarding, so it does not matter whether your mail lives in Gmail, Outlook or a custom domain. You point a rule at your Cerno AI address and can start with a single label before moving anything else.
