The little box at home
Picture the box that brings the internet into your house. Next to it sits a second box, about the same size. You plug it in once and then you forget about it, like the fuse box under the stairs. It quietly minds what comes in and what goes out.
That box is real, and it is called Semek. In its own words, Semek is your AI buddy, a friendly little box that sits next to your router. In every browser in your home it spots photos, videos and text made by AI, and it labels them, blurs them or turns them away. All the intelligence lives inside the box itself, in your home, instead of in somebody else's cloud.
You decide what it turns away and what it lets through. It is your box, and the settings are yours.
That is half of what the box does, and it already works. The other half, the one about what leaves, comes further down.
Semek is a working prototype by Aaltra, a Belgian technology company, together with Freehold. A prototype is a first working version rather than a finished product you can buy in a shop. What it does today is the start of the list and not the whole of it. More gets added as time goes on, and adding more is part of the job described further down this page.
Today it is a box in a house. That is where this starts and not where it stops. The same thing can run on the phone in your pocket, for all the hours you are not at home. It can run in a factory or an office, where a business has exactly the same two questions about what it lets in and what it lets out. A family, somebody on the move and a company all want the same thing here. What changes is the size of the box, not the job.
The two directions
Think of the box as a door with somebody standing at it, and that somebody works for you.
Coming in. The internet sends you an enormous amount of rubbish. Most of it is not dangerous, it is just a waste of your time, and you have to wade through it to reach the few things worth having. The box pushes the good things to the front. It looks at where something came from and whether a machine made it. And it follows your rules, not the rules of whoever sent it.
Going out. Right now, when a company wants to know something about you, you hand over your information. Once you have handed it over, you have no idea where it goes next. Freehold turns that around. The company sends its question to your box. Your box works out the answer, in your house, and sends back only the answer. Your information stays put.
You set the dial for both directions, and one of the settings is off. Off is allowed, and it always will be.
Both directions are the same job seen twice: making sure that what reaches you is worth your time, and that what leaves you buys you something back.
The sealed note
An insurance company does not need your medical records. It needs to know one thing, say whether you are fit to drive right now. A shop does not need a list of everything you have ever bought. It needs to know whether this jacket is your size. In both cases the answer is a tiny piece of the whole, and that tiny piece is all they actually need.
The answer does not travel on its own. It travels inside something like a sealed note. The note says who worked the answer out, what the answer is, who is allowed to read it, what they may use it for, and when it stops counting.
A driving licence works much the same way. It proves you can drive without you having to sit the test again in front of everyone who asks. The difference is that a new note gets written every single time, instead of one card lasting ten years.
Lots of boxes together
One box in one house is handy. A few million of them, all speaking the same language, is something much bigger.
Think about plug sockets. Everybody agreed on one shape of socket. Well, almost everybody, and mostly only inside their own borders, which is why a holiday still means a bag of adapters. But within one country it held, and that turned out to be enough. After that anyone could make a kettle, a lamp or a games console and know it would fit the wall. Agreeing on the shape is the hard part. It always is.
The people who ran the electricity network never made a single kettle. They ran the network, and that was the job.
Freehold works the same way. Aaltra makes the boxes. Freehold runs the network that all the boxes hang on, and lets other people build things for it.
Running it means two jobs. The first is keeping every box up to date, so that the software inside yours does not go stale while the world moves on. The second is making the network worth more as time goes by, by adding useful things it can do and by letting other people add theirs. A box that can do more for you this year than it could last year is worth having. One that stands still is not.
Not just any program is allowed to run on your box. Every one of them has to be checked first and put on a list. If it is not on the list, it runs nowhere.
Whoever decides what goes on that list has a lot of power over everybody else. That is too much power for one company to hold, so Freehold does not hold it alone. A separate organisation decides, with its own board, rules anyone can read, and a way to complain if you are turned down.
The huge AI models outside
Somewhere out there are the giant AI systems, the ones that need a warehouse full of computers to run. Your box is not one of those and never will be.
Freehold keeps your box up to date on purpose, so that it can go on working alongside those giants instead of falling behind them. What comes down that line is software: new things the box can do, and new checks for it to run. Your files never go up it. It does mean Freehold is a company you have to keep trusting, in the same way you already trust whoever updates your phone. Most questions it simply answers itself, at home, in a moment. Every so often a question is genuinely hard, and one of the giants is better at it.
When that happens, the box is the doorman. It decides what to send out, and it sends as little as it possibly can. It sends the paragraph that needs reading, and it holds back your name, the rest of the file, and what you asked yesterday.
Here is the part that matters. The box is allowed to use a giant. It must never need one in order to think. If it needed one, everything would end up out there again, and we would be back where we started.
Three misunderstandings
It does not sell your data. Data cannot really be sold. A copy costs nothing to make and looks exactly like the original, so there is never a shortage, and without a shortage there is never a proper price. An answer is a different thing. It is made for one person, about one question, at one moment.
It does not read through your files. Your files stay put on every setting, including the setting where you let nothing through at all. What gets shared is one short answer, never the material it was worked out from.
It does not pay you for your data. What you get back is a better deal: the offer that actually suits you, better terms, or a warning about your own car, your own boiler or your own health. That last one cannot be sold on to anybody else.
The name and the patent
Freehold is an old English word for land you own outright. The opposite is land you are only allowed to use, for as long as you keep paying the person who really owns it. Almost every website today works the second way. You get to use it, and you pay with information about yourself, which is the one thing you never get back.
A farmer who owns a field sells the crop. They do not sell the field, and they do not let the buyers come and dig it up.
The way all of this works is the subject of a European patent application, number 26202295.7, under the title Improved authentication for processing requests, filed on 1 September 2026. Freehold Works is the company that builds and runs the network. A separate foundation watches over how it gets used.
