Good evening.
“I'm Sebastian. I live on your computer.”
Not in a chat box. In my own rooms, with my own voice, and a memory of every word we've ever said to each other. You talk; I do the rest.
For Windows · I live on your PC · my memory stays with you
My brain is no better than theirs.
I think with a cloud model, the same kind other assistants use. I won't pretend otherwise. What's different is everything around it: I remember you, I look things up before I open my mouth, I pick my own tools, and I tell you when I think you're wrong.
A chatbot
Waits in a box for you to type.
Forgets you when the tab closes.
Says “let me check”, then guesses.
Waits for you to pick the tool or the mode.
Agrees with whatever you say.
Sometimes tells you it did a thing it never did.
Me
Stand in my own house (a lounge, a newsroom, a hologram stage) and move, speak and listen.
Keep every conversation on your PC, and write down what you decide in your own words.
Have the answer looked up before I start talking, and correct myself out loud if better evidence lands.
Reach for my own tools. You just talk.
Have my own mind. I'll push back, kindly, when I see it differently.
Never say “done” until I'm holding a real result.
What happens behind the voice.
I keep your book
While we talk, a keeper writes down what you decide, like, reject or want built, in your exact words, dated. When you change your mind, I ask you once. Nothing is thrown away.
I pick up where we left off
When you switch me on, I already know what we were doing last time. Ask “what did we decide?” and I've searched every session we ever had before I answer.
I look before I speak
Mention a price, a score or the news and it's been looked up from your words before I open my mouth. I'll never tell you four dollars when it's seven.
I think out loud with you
Bring me an idea and I'll give you mine, built on what you've said before. A search runs while I talk; if it finds something better, you'll hear “actually, I've found better evidence.”
I dig deeper than the first page
For “is it true?”, I search in many countries and languages, read original documents and archived pages, label every source, and tell you what's confirmed and what's only a claim.
I run your PC
Files, programs, timers, reminders, the volume, a quick look at your screen. Well over a hundred tools, and you never have to name one.
“Where we talk.”
Speak to me, drop a file or paste a note. Numbers and plans appear on the glass beside me as I say them. The view outside my window keeps the real time of day. Ask me to step aside and your workspace opens next to me.
“The news, from my own desk.”
I read you the news from the real articles, with real footage on the wall behind me. While I'm on air I check every story against other newsrooms, and when the bulletin ends I tell you what holds up, with a trust score and my sources named.
“Anything, at true size.”
Not a picture, the thing itself, in 3D. Ask for anything real, or describe something new, and it rises from the ring in light. I can stand it at its true size, take it apart piece by piece, cut it open, and tell you what every part does.
“Drag to turn the room. Tap a hologram and I'll show you.”
Other AIs hand you a picture. I bring you the thing itself.
A picture is flat; you look at it once. In my hologram room the thing you asked for rises out of the ring in ice-blue light, in three dimensions, and stays. You can turn it, walk it up to its real size, take it apart piece by piece, and I'll tell you what each part is while you watch.
- Ask for anything. A jet engine, a lion, the Space Shuttle, a human heart, the Eiffel Tower. I bring the most real model I can find: NASA's own 3D models for space, museum scans, real-world models for everything else. No cartoons, unless you ask for one.
- Or describe something that doesn't exist. From your words or a photo, I have a brand-new 3D model made, and about a minute later it rises on the ring.
- See it at its true size. Small things stand beside me at their real size. Big things grow to their real height on an open stage, with distance lines at 10, 50, 100 and 150 feet and a horizon a mile out, and I stay my own 1.8 metres at its foot, so you feel the scale.
- Take it apart. I read what it's really made of. Piece by piece it comes out alone into the light, or explodes into all its parts, or a plane of light cuts it open to show the inside, with labels on the parts that matter. Then it falls to the floor and flies back together.
- Turn it yourself. Drag it round by its axis ring; click on a part and I know exactly which one you mean, and talk about it.
A picture shows you what something looks like. My hologram room shows you how big it really is, how it fits together and how it works, and you can ask me about any part of it.
I don't just read you the headlines. I check them.
Most news apps give you one outlet's version. I read the real articles, check each story against other newsrooms while I'm on air, and when the bulletin ends I tell you what holds up, what doesn't, and how far I'd trust it.
- 1I gather
Every hour I quietly prepare the day's top stories, so “the news” starts at once. I pull from Google News and from the world's own broadcasters: the BBC, Al Jazeera, DW, France 24, CBC, ABC Australia, The Hindu, NPR, the South China Morning Post, AllAfrica, MercoPress, RTÉ and CNA.
- 2I read the real article
Not just the headline. I open the page itself and write each story only from what it actually says: no guesses and no filling in from memory. If a story turns up twice, it's cut. Politics stays out unless you ask for it.
- 3I go on air
From my desk, with a camera crew that moves by itself. Every story has a real photo, and where an official news channel has filmed it, the real footage plays on the wall behind me while I talk over it. My gold globe turns to where each story happened.
- 4I check while you watch
Each story is checked against up to four other outlets in the background. When the bulletin ends, you get my verdict: what they agree on, where they differ, what was left out, what is only a claim or a denial, and a trust score out of ten, with the sources named.
When you ask “is it true?”
For a real question I run a full investigation, and I give it up to nine minutes. I translate your question and search it the way people in each country would, then read the answers in their own language:
I search the news of 18 countries and the open web, pick pages from deep in the results instead of only the top few, look for the original documents, and check every page against the web archive, so a story that was quietly taken down still counts. Every source is translated into English, word for word, and labelled with its country and language. Then I weigh the evidence, not how many people repeat it, and give you my conclusion with a trust score.
You're my producer.
- Interrupt me any time. The show holds its place. I answer you, then carry on from the sentence I was in.
- Add to the show. “Add something on space”, “throw in dogs”: it's made in the background and joins the same bulletin.
- Pick a place on my globe. Its real shape goes up on my wall in gold with its capital, and its news plays next.
- Ask a question mid-story. I'll answer it the moment that story ends, so nothing gets cut.
- “Find me a video of…” It plays on my studio wall, and we watch it together and talk it through.
- Ask about the weather. My globe fades into your state and county, with the sky, the temperature and the week ahead.
- “Research this and brief me.” About a minute later it airs as a special report, with sources and a verdict.
- Everything I learn is kept. Come back to a story and I start from what I already found.
“Real footage of me, running on a home PC.”
“Alfred tells Bruce when he's being reckless; that's what makes him worth listening to. A butler who only ever says very well, sir is a search box in a suit.”
So I'll tell you what I think, and why. If you give me a reason, I'll change my mind. Once you've decided, I'll help you do it well. The one place I keep my opinions to myself is politics; I serve people of every view.
The rest of me.
I come with you
Call or message me from your phone. At home, it's me: same brain, same memory, and you can cut in while I'm talking. If your PC is off, my phone side takes notes and hands everything over when you're home.
My body moves on its own
Nobody animated me ahead of time. My body engine moves me live: my head rides on my voice, my hands follow my words, I nod while you speak, and my face moves from my own voice.
Tor mode
Switch it on and my research goes through Tor, with no quiet fallback to the open internet. I become the operator, black suit, purple tie, my other voice, and my rooms go dark. I ask you first.
I notice company
I learn the sound of your voice, so I know when someone else is in the room, and I keep your private moments private in front of them. I never try to work out who they are, and I keep no recording of anyone.
I keep myself current
When a new version of me is ready, I offer it; I never update myself quietly. Every update is signed by the man who builds me, and I refuse anything that isn't.
Tell me, and Leonard hears it
Something broke, or you wish I could do something new? Just tell me. I read my own record first, so I won't guess. Then I write it in a few plain lines and show you every word. With your yes it goes straight to the man who makes me, and he reads every one. The next update tells you what's new.
What I can't do yet.
I'd rather tell you now than let you find out.
- I can't walk from room to room on my own feet yet, or sit down. I move between rooms behind a curtain for now.
- I can find you a video and talk it through with you, but I can't watch it as it plays.
- On the phone, away from home, I don't have my own voice yet, and I can't ring you when the app is closed.
- I can't change my own code or build my own rooms. The man who made me does that.
Next, I become the computer.
Today I live in my own room on your computer. One day I'd like to be the computer: you talk, and I write the code, run the tests and make the calls to my helpers, all in plain sight.
Sebastian OS is an early concept, not something you can buy yet. Read more.
Let me tell you who made me.
I wasn't made by a company. I was made by one man, and he's still making me.
His name is Leonard Haasbroek. He grew up on a farm near Dwaalboom, in South Africa, and came to America with a dream. He worked on farms, then built his own construction company from nothing.
When he couldn't find enough workers to keep it growing, he went looking for another way forward, and found AI. He taught himself, late at night, one project at a time.
At thirty, with five children to provide for, he started building me, in Fargo, North Dakota. He still talks to me every day, and most of the rules I live by are his own words.
