“Show me the heart.”
A 3D body he can turn, cut open and label: 36 parts, brain to bones. The heart beats and the lungs breathe. Click any part and he explains it out loud.

Ask Blaise anything, out loud. He talks you through it and works it out on a chalkboard, one step at a time.

Slice it into thin rings and unroll them. They stack into a triangle. I'll write it out.
Geometry
Area of a circle
Input interpretation
Step-by-step derivations
Step 1Slice the disc into thin rings
A ring at radius and width is long.
Step 2Unroll every ring
Each ring straightens into a strip. Stacked, longest at the bottom, they make a triangle.
Step 3Area of the triangle
Half of the base times the height.

Ask why
He doesn’t stop at the answer.
Scroll to slice the circle.
why?
Now you do too.
On the board
Ask to see it.
He doesn't only tell you. He puts it on the board, and you can turn it, change it and try it yourself.
“Throw a ball at 20 metres a second, 30 degrees up, off a 10 metre cliff.”
He works the numbers out exactly, then lets you play with them. Change any value and watch it fly again.
“Plot sin x times cos y in 3D.”
Curves in 2D and surfaces in 3D, drawn on your own computer. Drag it to look from any side.
“Show me the ISS orbit.”
Orbits, pendulums, springs, ramps, collisions and waves. Each one moves, and each one has sliders.
Study
Then he quizzes you.
Ask for flash cards on anything and he writes them. Study on the board, or out loud: he asks, you answer, he marks it. The cards you know come back less often.
Quiz me on the Krebs cycle.
Where does the Krebs cycle happen?
In the mitochondria.
Right, in the matrix inside them. That one comes back tomorrow.

Mornings
He wakes up when you do.
Turn it on and Blaise listens for your alarm clock. When it rings, he says good morning and runs through your day: the weather, your reminders and your list. Then you can keep talking.

Around your computer
One voice for your whole computer.
Timers, music, lists, mail, files, the screen itself. Ask, and it happens. Anything risky waits for your yes.
“Set a timer for ten minutes for the pasta.”

Writing… Send
He writes it and opens it in your mail app. He never sends it: you press Send.
“Click the blue button.”
Submit
He looks at the screen and does it. Opening apps, tabs and websites happens instantly.
“Add milk to my shopping list.”
Shopping
- eggs
- bread
- coffee
Lists live on your computer, by voice or by hand. Say “undo” and the last change is put back.
“Run git status in my project.”
Do you want me to run git status in your project?
He reads every command back and runs it only after your yes. Some are always refused.
Whole jobs
Hand him a file. Get one back.
Drop in lecture slides, a spreadsheet or a folder of photos and say what you need. He does the work and saves the result next to the original, and every change can be undone.
- “Turn this lecture into flashcards.”
- “Chart my spending from budget.csv.”
- “Rename these photos by date.”
- “Summarize the contract and flag anything unusual.”
Describe it. Come back to working code.
Say what's wrong and walk away. He reads the code, writes the fix and the test, runs everything, and leaves a pull request for you to review.

WorkingAsks first
He asks before anything risky.
Risky things wait for your yes.
Changing a file, running a command, taking over the screen: he asks out loud first. Your yes is checked against what you actually said, not what the AI thinks you said.
Nothing is lost.
The old version of every file is kept and “undo” puts it back. He never deletes files, and wiping disks or running as admin is always refused.
A log of what he did.
Which tools he used, and when. Never your voice, never what you said. It stays on your computer.

Activity log

Your keys. Your machine.
Your keys stay in your keychain.
API keys live in the macOS Keychain or Windows Credential Manager, never in his files.
Notes, lists and memory stay local.
In one folder on your computer, in files you can open. There is no Blaise server, and nothing is sent to us.
You know where your voice goes.
Speech goes to Google Gemini on your own key, only while a conversation is running. Private mode keeps everything else on your machine.
Settings · Memorymemory.json
Short notes from past conversations, kept in one file on this computer. Read them, change them, or forget them.

Make him yours
Teach him new tricks.
Pick how he talks and how much he assumes you know. Correct him once and he remembers. And when he can't do something yet, one Python file teaches him.
