Build worlds from nothing.
Yamis turns your computer into your own artificial intelligence. It finds out which model works best on your hardware, sets it up and gives you agents that code, edit files and complete tasks for you – no subscription, and your data never leaves your home.
Free · Windows, macOS and Linux · Browser, Android app and command line
Mimir checks your computer – processor, memory, graphics card – and tests with real tasks what it can do.
You decide how much power the AI may use. Yamis picks the right one from freely usable models and sets everything up.
Talk to Yamis in the browser, in the app or on the command line. The agents work step by step – and ask you before every change.
Yamis reads your project, writes and reviews code, runs tests and explains what it did – right in your project folder.
Checking updates, setting up services, finding problems: Yamis looks after your servers – every change only after your yes.
Design 3D objects for printing, analyse PDFs, understand voice messages. Just say what you need – Yamis works out how.
Plan, act, verify – on their own, but never without your yes. Dangerous commands are blocked, every step stays traceable.
Browser, Android app, command line, editor and terminal – all talk to the same Yamis and the same conversations.
No ads, no tracking, no selling of your data. Your model runs on your computer – not in a corporation’s data centre.
In a tandem, several people work with Yamis in the same command-line session – everyone sees what the others type and what Yamis does.
Tell Yamis once what matters to you – a language, a style, a rule. It keeps it in mind for every task that follows and forgets it when you say so.
Drag or paste screenshots and images into the command line – Yamis looks at them and carries on with the work.
Spec sheets say little about whether a model really works on your machine. Yamis measures it – with real programming tasks.
The name brings two figures together. Ymir is the primordial giant of Norse myth: born in the void between fire and ice, his body became the world. Raw strength from which something great arises.
His digital counterpart is a companion who is uncannily clever, always there and a loyal friend. Yamis is both – the power of your own computer and a digital best friend who helps you.
That is why the sign in the rune ring, why ice and ember: your hardware becomes your own AI world.
Our programs are named after figures from Norse tradition. Not as decoration: the old story tells quite precisely how they relate to one another.
Where the ice of Niflheim met the embers of Muspelheim, Ymir arose, the first giant. The gods shaped the world from his body – the earth from his flesh, the sea from his blood, the sky from his skull. At its centre lies Midgard, the world of humans.
The dwarves first stirred in Ymir’s flesh, Snorri’s Edda tells us, and the gods gave them understanding and human shape. They live in earth and rock and are the great smiths of the sagas. One of them is Sindri – so he, like every dwarf, comes from Ymir.
The nisse does not come from the Edda but from Scandinavian folklore: a small house spirit who watches over house and farm as long as he is treated well. He lives where people live – in Midgard, the world made from Ymir.
The world made from Ymir is held together by the world tree Yggdrasil. One of its roots reaches to the frost giants, Ymir’s descendants – and beneath it lies Mímir’s well, where wisdom and understanding are hidden. Odin gave an eye to drink from it: knowledge that rests deep in the world and can be fetched by those who give something in return.
That is how the programs fit together too. Yamis is the strength everything comes from. Code takes shape in Sindri, the forge. Nisse keeps watch over the terminal in your home. The app takes Yamis out with you, and your own model draws its knowledge from Mimir’s well.
They all talk to the same Yamis and the same conversations. Anything still being built says so.
The core
Named after Ymir, the primordial giant from whom the world was made.
The server, with the chat in your browser and the agents that plan, act and verify. All the other programs talk to it.
In use
The forge of the gods
Named after the dwarf smith. In Snorri’s Edda the master is called Eitri; many retellings call him Sindri. With his brother Brokkr at the bellows he forged the golden boar Gullinbursti, the ring Draupnir and Thor’s hammer Mjölnir.
A development environment for PHP – with Yamis right beside it: questions about the code, suggestions as you type, and changes you see as a comparison first.
In use
Click the workshop and Sindri forges on.
The keeper of the terminal
Named after the nisse, the house spirit who watches over house and farm.
A terminal and SSH program for the desktop; it comes with the Yamis CLI. An image on the clipboard lands in the terminal as a file – handy for showing Yamis a screenshot.
In use
The well of wisdom
Named after Mímir, keeper of the well of wisdom beneath a root of the world tree Yggdrasil. Odin gave an eye to drink from it and later still sought counsel from Mímir’s head. In the same way you give Mimir a share of your computer – and keep the knowledge at home.
A desktop program for Windows, Linux and macOS. It measures your computer, lets you decide how much power the AI may use, and recommends the model that runs best on it.
Being built
Measuring, setting limits and recommending already work; downloading and setting up the model come next. A first preview is available for testers under Downloads.
Programs used to have a heart: a figure you recognised, a small movement you missed when it was gone. Today most of them look the same – correct, but lifeless.
We want to bring the two back together. Each of our programs has a character, and it moves only where it has something to say. Above all while you wait: waiting is part of working with AI – so it should at least be a small experience, not an empty spinner.
The ember core in the send button breathes while Yamis works on the answer – and only then.
When a program, a test or a build runs, Sindri’s eyes glow. When Yamis is working, his hammer strikes and sparks fly.
When the terminal has nothing to do, the nisse lets his cap droop and his lantern glows. For long commands he reaches for his pickaxe, saw or noodle pot.
If you have asked your operating system for less motion, the figures stay still – on this page too.
Yamis was not born in a corporation but at a desk. A single developer built it in his spare time – on his own hardware, with his own money – and uses it every day: for programming, for his servers, for his own apps.
The drive: AI should belong to everyone, not just to a few with huge data centres who decide what is good and what is not. It should be private, and simple.
Today Yamis works with freely available models that others have trained. The dream is to train our own models – as good as the big ones and still small enough for your computer at home. That takes a lot of computing power: a dedicated AI server with several powerful graphics cards, around 30,000 euros today. It is a goal, not a plan with a fixed date.
How Yamis will be funded in the long run is still open. Right now there is a single developer who pays the costs himself – the future will show what comes of it. One thing is certain, though: Yamis will not be stuffed with ads. The goal is a fair system that sustains itself.
Ideas, questions or want to join in? Write to yamis.agent@gmail.com.
An address on our own mail server is planned – right now the cost is not yet worth it for the project.
Yamis is already in daily use. The version for everyone – with the Mimir program that measures your computer and sets up the right model – is being built right now. We are opening step by step, and everyone who joins helps shape it: just open a ticket in Yamis with your wish.
We invite people in small groups. Sign up – your access details will arrive by email.
