Ex libris

Latin for from the library of.

For more than five hundred years, readers have pasted a small print inside the cover of their books. It carried a name, and it said one thing: this knowledge is mine.

The shift

Then knowledge learned to think.

AI can now reason, remember, use tools, make plans and take actions. It is becoming less like a tool we use now and then, and more like an intelligence we work with every day.

Somewhere else

But it doesn't live with you.

We reach it through products and accounts, while the models, the memory and the infrastructure behind it are controlled somewhere else.

Who will own the intelligence that knows you, works with you, and acts on your behalf?

Ex Libris

So we are bringing it home.

An intelligence that belongs to you. It lives on your own device, understands your world, reasons about your goals, uses tools, takes action, and grows with you.

Why now

For years, we imagined AGI as one giant system. Something is happening before it arrives.

  1. 01Models are small enough to run on our own devices.
  2. 02Agents can use tools and complete work.
  3. 03Machines can reason over more of what we give them.
  4. →For the first time, the pieces exist for intelligence to become personal.

The library of you

You are already a library.

Everything you learn and create over the years forms a personal library. Until now, no intelligence could carry it with you, understand it, and use it to help you act.

It grows with you

Every project adds context. Every decision adds knowledge. Every experience makes it more useful the next time you need it.

Your plate

Every library begins with a name.

Write yours, and this page makes your first bookplate, painted from your name. It is made in your browser and never leaves your device.

We believe this kind of intelligence should be something anyone can own.
