AI Chief of Staff

The executive assistant that reads every email — and proves what it saved you.

Across six companies. In your voice. Always on. Fully transparent.

Use the arrows below, or click a section above.

Get to know you · Onboarding

It already knows you

Day one it reads 60 days across every mailbox. It doesn't make you configure anything — it shows you what it noticed and asks permission. ~5 minutes of quick cards.

Automatic calibration · human-gated · per-company
I've read your last 60 days. 47 newsletters last month — you opened 2.
What I'll do
File them to ACoS Newsletters — one line in your evening digest, never deleted.
Get to know you · Voice

It learns your voice

It studied your sent mail — greetings, length, sign-off, tone — and built a voice profile. Drafts sound like you. You review and send; it never sends for you.

Voice profile from sent mail · propose-only drafting
Draft · in your voice

Hi Sam — thanks for the quick turn. The $700K–$1.5M range works; let's lock the platform call for Thursday. Best, Pierre

Matches your usual brevity + Thursday preference. Sits in Drafts — you send.
Do the work · Triage

It triages every email the moment it lands

Live, 24/7 — not a weekly summary. As each email arrives it's read, judged against your rules, and sorted in place — instantly.

  • As it arrives → labeled into a section + importance, in seconds
  • Predefined rules fire first; AI judgment handles the rest
  • Newsletters/promos file themselves on arrival
  • The few that truly need you rise to the top

98% handled automatically. You see only the 2%.

Do the work · Inbox

Your inbox, sorted in place

Three colored sections, applied right in Outlook as mail arrives: ① To you, ② Action needed, ③ FYI. See at a glance what's truly yours. Nothing deleted.

Do the work · Filing & cleanup

It clears the backlog — with your tap

Thousands of old emails? It groups them and asks once per group: file, adjust, or skip. Nothing moves without your approval, and nothing is ever deleted.

Do the work · Drafting

The reply is already written

For mail that deserves a response, the draft is waiting in your Drafts — in your voice, with the thread's context. You glance, tweak a word, send. It never sends for you.

Re: Operator-buyer — "the range works; Thursday for the platform call."

Re: Telematics meeting — "Tuesday works; send the deck beforehand?"

Prepared, never sent. You stay in control of every send.
Do the work · To-dos

One to-do list, kept for you

It pulls to-dos from your email, your chats, and the loops you'd forget — that quote with no reply in 12 days — into one ranked list, overdue first, with due dates. Surfaced in a morning briefing and on a Focus tab.

Do the work · Always on

An always-on agent you just talk to

It lives in your Teams chat. Ask it anything — "draft a reply to Sarah," "what's waiting on me," "file everything from this sender." And it's proactive: it reaches out first.

  • Breaks through instantly for a VIP, even off-hours
  • Goes quiet during meetings — reads your real free/busy — except VIP contacts
  • Nudges you with the morning briefing and the evening digest

You're free now — flagging immediately.
You, 2:00pm (in a meeting)
A normal-urgent email arrives → held quietly for the digest. No buzz.
Do the work · Digest

End of day, in one note

At 5:30 it sends one brief: everything it did, and the handful of things that still need you. Not a wall of links — a note from your chief of staff.

Scannable end-of-day digest
End-of-day digest — Monday

I handled 488 emails for you · 8 need your eyes · 5 waiting on a reply.

🔴 Needs you (8) · 📁 Handled automatically — 471 filed, 364 tagged. Reversible.
Keeps learning · Rules

It suggests rules — like a senior EA

When it spots a pattern, it offers to make it a rule: "I keep seeing mail from this sender you never reply to — auto-file it from now on?" One tap. Reversible. It batches, never nags.

Six companies. Then the next executive.

Built for six tenants from day one — every record scoped per principal and per company, never shared. Adding the next executive is onboarding, not a rebuild.

The one line

"An executive assistant that reads every email across all your companies, learns how you work, handles 98% of it transparently, drafts the rest in your voice, protects your attention — and proves, in hours and dollars, what it saved you."
