Product · In development
A desktop operating system built on Linux, with an AI assistant woven through the system rather than bolted onto it — and without the telemetry, the upsells, or the account you never asked to create.
GRACE is not a chat window you open. It orchestrates a Pantheon of smaller, specialized agents, has context on what you are working on, and can act across the whole desktop — within the approval limit settings in our governance policy.
MythOS supports local language models, so the assistant keeps working when the connection does not — and your work does not have to leave the machine for the assistant to be useful.
The system ships as a set of purpose-built modules for writing, music, design and development, rather than a blank desktop and a shopping list of software to assemble yourself.
Pacing, focus, and how much the interface asks of you at once are treated as first-class design constraints — decided at the start, not patched in at the end.
Retrieval, not recall
Every language model carries a fixed snapshot of the world, frozen on the day its training stopped. It will answer confidently from that snapshot long after reality has moved on — and it has no way to notice that it has, because stale knowledge and current knowledge feel identical from the inside.
So our agents are built to retrieve before they answer. Ask one about your project and it reads your project, not its memory of projects. Ask it about a tool and it consults that tool's current documentation. What it recalls is treated as a hint; what it retrieves is treated as evidence.
This is not a performance optimisation. It is what makes the rest of our governance possible: an agent that retrieves can cite, and an agent that cites can be checked. One that merely recalls can only assert, and asking a person to approve an assertion they cannot verify is not oversight — it is a signature on a blank page.
The same discipline is why this company's AI-assisted work is written to verify against live sources rather than trust a summary of them. We have watched it catch real errors — including our own, including on this site.
Where it stands
MythOS is in active development and is not yet generally available. It builds as a real bootable Linux distribution and has been installed and run on physical hardware. An ARM64 build is in progress alongside the desktop one.
We would rather say that plainly than run a countdown clock. If you want to know when it is ready, tell us and we will tell you.
