A full mail client and calendar, built in

Not an integration that reads your inbox: an actual client, with the assistant already inside it.

Most assistants read email through a connector, which means they see messages and nothing else: not the thread state, not the drafts, not what you archived without replying.

Heyno ships a real mail client and a real calendar so the assistant works with the same information you do.

Why a client and not a connector

A connector gives an assistant a keyhole view: recent messages, maybe a search. It cannot see that you left three threads unread on purpose, or that the draft you started yesterday already says half of what it is about to suggest.

Owning the client removes that gap, and it removes the sync lag that makes connector-based assistants confidently out of date.

A client sees thread state, drafts, and what you deliberately ignored.
A connector sees a keyhole view and a sync delay.

Triage that is actually triage

Triage means deciding what does not need you. The assistant separates what genuinely requires a decision from what needs an acknowledgement from what needs nothing, and it explains the split rather than silently filing things away.

Triage is deciding what does not need you, and saying why.

To M. Ellis

Morning Mark. The revised scope adds the second riser, which is about a day.

Friday is still possible if the inspection passes Thursday morning. If it slips we are looking at Monday. I have held 11:00 Friday for sign-off either way.

To K. Osei

Thanks for the enquiry. Two units at this spec falls outside the standard rate card, so I have not put a number on it here.

Sending it to you for a price rather than guessing.

escalated · needs a price from you

To Brightwater Supply

Invoice 40218 shows £4,180. Our delivery note for the same order shows £3,940. The difference is the pallet charge, which was waived on the call of 2 July.

Attaching both. Happy to settle the agreed figure today.

Conflict

Payroll cut-off moved to Wednesday, which collided with the two routed site visits.

Payroll is marked immovable, so the second visit shifted to Thursday afternoon, the only slot that still cleared travel time from the depot.

resolved without asking

Scheduled against travel time, buffers, and the one commitment that could not move.

Drafting in your voice

Voice is learned from what you have actually sent: length, greeting, how direct you are, whether you use the person’s first name. A draft that does not sound like you costs more to fix than to write.

Tone is derived from sent mail, per correspondent.

The calendar as a constraint system

A calendar is not a list of events, it is a set of constraints. Travel time, buffers, working hours, other people’s availability, and the one commitment that must not move all bound what can be scheduled.

The assistant schedules against those constraints and refuses to create a conflict quietly.

What it never does alone

Sending is an action that leaves the building. Drafts are produced freely; sending follows the workspace approval policy, and the policy is visible to the person approving.
