What people ask, answered plainly.

The metadata of your mail: the sender's name, email and domain; the date and time received; how many people it was sent to; who you write to, from the To and Cc of mail you send, never its Bcc; which addresses you send from; existing labels on the message; whether it's a reply or a thread; whether a mailing offers a one-click unsubscribe, and whether Gmail confirmed its sender signed that offer; how many messages your mailbox and its labels hold, never how many are unread, and how far back it goes.

Never the subject line of any message; the body of any message; attachments of any kind; anything you've drafted but not sent; anything in Drive, Calendar, Meet, or Contacts; anything we'd use to train a model.

Brood decides what to propose by rules and counts you can read, and never sends your data to a model, its own or anyone else's. If you point an assistant of your own at what Brood has learned, that is your assistant, reading your record, because you asked.

Yes, and with a personal Gmail account. Brood is made with work mail in mind, which is where the noise has consequences.

If this is a work account, its administrator may have to allow Brood first. If so, Google says so on its own page, and nothing is connected.

A filter does what it was told, for as long as it exists. Brood writes Gmail filters too, but it decides which ones from who actually writes to you and how often, proposes each before it files anything, and keeps them current as senders come and go.

It also does what a filter cannot: it brings back a reply in a conversation you wrote in, and a customer who has been away a while, and it puts back anything from a sender you have said must always reach you, if a filter filed it anyway.

Brood is running, and not yet open to everyone. Google reviews an app like it before it opens to the public, and the review can take months, so there is no date to promise.

Brood starts with the inbox. Next, what it learns will reach a command line and the AI assistant you already use. Then the calendar. After that, whichever channel the people using it say is loudest.

Every new mailbox starts with a free audit: Brood reads the last 30 days once, shows you what it found and what it would file, and changes nothing.

Filing that mail, and keeping it filed as new mail arrives, is Pro: $9 a month for one mailbox billed once a year, or $12 a month billed monthly, and $5 a month for each mailbox after the first. Prices are before sales tax, which is added where it is owed.

The first time you start Pro without a code, it begins with a trial of 30 days on one mailbox. We ask for your billing address, to work out tax, and not for a card.

At www.noisybrood.com/privacy/, which you can read before signing up, as can anyone.

In short, Brood reads the metadata of your mail and never the subject line of any message; the body of any message; attachments of any kind; anything you've drafted but not sent; anything in Drive, Calendar, Meet, or Contacts; anything we'd use to train a model.
