Stratumus
Coming late 2026

Your computers, working together as one private AI.

Stratumus turns the Macs and PCs you already own into a private AI system. What you ask, write and upload never leaves your devices.

Set-up is plug and play. Advanced controls are there when you want them.

From question to answer without leaving your home.

Every request takes the same four steps, and every step runs on hardware you own.

  1. You ask

    Ask a question or hand over a task from any device in your home.

  2. Stratumus picks the model and the machine

    It checks what your request needs and what each of your computers can handle right now, then chooses the best match.

  3. One of your computers does the work

    A Mac or a PC in your home runs the model. The request never touches a server that isn't yours.

  4. The answer comes back to you

    The reply returns to the device you asked from. It isn't copied elsewhere or used to train anyone's models.

Pick how it thinks. Stratumus picks where.

Most of the time you can leave it alone. When you do want to choose, there are two settings. Try them.

Speed: your laptop runs a lightweight model, so replies start quickly.

What you ask stays with you.

Stratumus runs on your computers, not ours. Your questions, files and answers never pass through a server we control.

Everything runs on your own devices.

We do not train models on your data.

No ads.

Automatic by default. Manual when you want it.

Most people never open this. If you do, you can decide which model handles which kind of task, and which computer runs it.

Why run AI at home.

Your data stays yours

Cloud AI works by sending what you write to someone else's computer. Stratumus doesn't, so there is nothing on a server to leak, sell or mine.

You already own the hardware

The computers you have sit idle most of the day. Stratumus puts them to work, so you aren't paying a provider for every request.

You decide what runs

Pick the models. Pick the devices. Turn it off. No outside company decides what your AI can do or when it stops working.
