Mail AI

Mail AI is a unified inbox inside Kaer. Connect a mailbox and it appears alongside any others in a single three-pane view: the account and folder tree on the left, the message list in the middle, and the reading pane on the right. On top of that sits AI triage, which works out what actually needs you, summarises the rest, and drafts replies that wait for your sign-off. One inbox habit, every account.

The layout

The three panes behave the way a desktop mail client does. The left pane lists every connected account with its folders, so you can scope the view to one mailbox or read across all of them. The middle pane is the message list for whatever you selected. The right pane shows the open message in full.

The fourth piece is the Today view. It is not a folder — it is a triaged slice of recent mail, ordered by what needs attention. Most people start the morning there: it surfaces the messages that need a decision or a reply, and lets everything else wait quietly where it was filed.

What triage does

Triage makes three passes over incoming mail:

1. Prioritises. Each message is assessed for whether it needs action, is worth reading, or can simply wait. The Today view is built from this ordering.
2. Summarises. Longer messages and threads get a short summary, so you can decide whether to open them without reading the whole thing.
3. Drafts. For messages that need a reply, the agent prepares one. The draft sits waiting — nothing goes out until you approve it.

That last point is the contract worth internalising: by default, the agent never sends mail without your approval. You read the draft, edit it if you like, and approve the send yourself.

Connecting a mailbox

Gmail connects through Google sign-in: choose the account, approve access, and the mailbox syncs into the tree. Each connected mailbox is a paid add-on, billed per mailbox, and available on any paid plan. Connection status and disconnection live at Mail → Settings.

Rules per mailbox

Each mailbox can carry its own rules and automations, managed from Mail → Settings. A rule is a standing instruction: file newsletters on arrival, flag anything from a named client, always draft a holding reply for support requests. Rules are scoped to their mailbox, so a personal account and a shared support inbox can behave completely differently without interfering with each other.

A worked morning

Here is a typical start of day with two connected mailboxes:

Today   14 new messages across 2 mailboxes.
        3 need attention:

        1. [email protected] — contract question. Summary + draft reply ready.
        2. [email protected] — payment failed. Flagged; no draft, needs your call.
        3. [email protected] — refund request. Draft ready, per your mailbox rule.

        11 filed: 6 newsletters, 3 receipts, 2 CCs — summarised, nothing needed.

You tweak the contract reply, approve both drafts, and handle the payment yourself. A few minutes in the inbox, and nothing was sent that you did not sign off.

Limits and edge notes

• Triage needs mail to work on. A newly connected mailbox may look sparse in Today until its first full sync completes.
• Drafts are suggestions, not sends. If one misses the mark, edit it or discard it — approval is always the gate.
• If a mailbox's grant lapses (for example, access revoked from your Google account), sync stops until you reconnect from Mail → Settings.

Good to know

• Is Mail included in my plan? It is a per-mailbox add-on on any paid plan — see Billing and Usage.
• Can the agent ever send on its own? Not by default. Mail sends are approval-gated the same way other external actions are — see Privacy and Safety.
• Where do the settings live? Mail → Settings, covering connections, rules, and per-mailbox behaviour.
