Kumia is a persona of you, the CEO. It reads what you can't get to and does the routine the way you would.
There is nothing new to learn. It lives in the chats your company already uses, and you talk to it the way you'd talk to a chief of staff. Nothing goes out without you.
It can tell you what was waiting on you overnight, answer the board's question with the real number, chase the hiring plan Priya promised, or reply to Hartono the way you did last time.
Use case 1
What was waiting on me overnight?
Kumia reads the chats while you sleep. In the morning it separates the few things only you can decide from the routine it has already drafted.

Revenue by pipeline this month?
Ask in plain words, during the meeting. Kumia takes the figures from your systems and shows where each one came from.

Use case 3
Did Priya send the hiring plan?
Kumia remembers what people promised you, and when. It finds the thread and what changed since, and drafts the reminder in your words.

Use case 4
Reply to Hartono the way I would.
Kumia drafts from your past positions and the rules you wrote in your persona. You read it, change a word, and send it as yourself.
Reply to Hartono the way I would.
Dewi decides; Arif only recommends. Their volume is up 30% this year, which is why they're asking now. Your persona says "never move on terms in the first reply; trade something smaller instead."
your past replies · Mar 14, Jul 2persona · "terms" ruleRework · Hartono accountHow it stays yours
Three settings decide what Kumia may hear, how it writes, and how much it may do without asking.
It lives in your chats.
WhatsApp, Zalo, Rework and Base today, Lark next. You choose which groups and one-to-one chats it may hear, and the smaller set where it may write. Nothing is heard until you choose.
Lark
It is a persona of you.
You write down how you decide, what you never say, how short your yes is. Every draft starts from those words. When you correct a draft, it remembers why.

How I decide. Fast on reversible things, slow on people and terms. If a question can be answered with a number, answer with the number first.
Terms. Never move on payment terms in the first reply. Trade something smaller: a discount for early payment, a delivery date, a pilot.
How I write. Short. First name, no "Dear". One ask per message. "Let me know" is fine; "please kindly" is not. Never exclamation marks.
What I never do in a chat. Promise a hire. Discuss salaries. Commit a date for Product. Agree to a price in a group.
Who decides. Hartono: Dewi decides, Arif recommends. Board: Amara speaks for the lead investor.
It asks before it acts.
It starts in Manual and asks before every message. When you trust it with the routine, you widen what it may do on its own. It never deletes anything, never changes who can see what, and never moves a private message into a group.

What the other side sees
The same day, from the other side. Every message Kumia sends in your name carries "via Kumia", so nobody is misled about who typed.
Daniel asked at 06:48, before you were up. Kumia drafted the answer from your last three orders with him. At 07:12 you approved it from your morning list. Daniel sees a normal message from you, marked "via Kumia".
You asked Kumia whether Priya had sent the plan. It wrote this reminder, including the Finance approval it had seen in Rework two days earlier. You read it and pressed Send. Priya answered in eight minutes.
Arif asked for net-60 on Wednesday evening. Kumia drafted this reply from the position you took in March and July. You changed one word and sent it as yourself. Dewi, who decides, accepted within half an hour.
Amara asked late Wednesday night. Kumia did not draft a reply, because board decisions are yours. It put her question first on your morning list, with the background. You typed the answer yourself.
