Companion
Nobody else reads the messages. Not us, not a model vendor.
Companion is an app you talk to in Hebrew about how things are going. It runs on a server its owner pays for, so nothing said in it ever leaves that machine.
Where it runsOn one server, the owner's own. Not on a laptop, and not on ours.
Who is this for?
Anyone who wants an assistant to talk to and does not want a copy of the conversation sitting on some company's servers. Until now the choice was a product that keeps your words, or nothing.
What the numbers mean
Checks that run on every change, so fixing one thing cannot quietly break another.
The data was restructured eight times without losing what was already inside it.
If the machine dies, it comes back exactly the way it went up the first time.
How it actually works
Companion was built for one person, and there is exactly one copy of it running in the world. You talk to it, it answers in Hebrew by voice or in writing, and it remembers what you told it last week. You can hand it a document and ask questions about it.
The difference is where Companion lives. The part that thinks, the memory, the files and the chat window all sit on that one machine. There is no account with anyone, and no copy of the conversation on a server somewhere else.
Some things a language model must not be left to judge on its own. So we put a fixed list of rules in front of it. Those rules read every message first, and when a message matches one of them the app does the same thing every single time, without asking the model what it thinks.
Installing it is one command on a blank server. It locks the server down, creates its own passwords, starts everything, and then restores the whole system from a backup to prove the backup actually works. Most projects promise to test their backups later. This one does it before you have used it once.
The setup guide names every choice a human has to make and every choice the installer makes for you, one line each. That is the difference between software you own and software you are renting from whoever installed it.
If your data is the kind you cannot hand to an outside company, Companion is proof you can still have the app, on a machine you own.
