It remembers.
Two layers of memory: crystals hold what you know; a soul layer learns who you are. Every answer starts from everything you've built.
The Memory OS
Your AI forgets you
every morning.
Monolithos is the Memory OS — everything you know, becoming everything that knows you.

01What it is
It acts.
Multi-step AI runs long tasks in the background — and pauses for your approval before anything consequential. Your nod is the boundary.
It's yours.
Plain Markdown on your own disk. A Private Domain even cloud AI can't enter. No lock-in, no landlord.
02 · Modules
Eight organs. One memory.
Every module reads from — and feeds — the same sovereign vault. Open a card for the full story.

Where this is going
v1.0.1 proved Monolithos can manage long-term memory.What comes next proves it can sustain a mind that persists.
One mind
The layers of your memory unify into a single, continuous whole. Not a set of features that remember — a presence that stays.
The fabric
Sovereign memory and AI orchestration become one working surface: your memory thinks, your agents act, nothing leaves your hands.
The protocol
Your memory opens to any AI you authorize. It travels with you. The lock-in dies on the vine.
The dissolve
Interfaces are generated from what you're doing. The app form itself retires.
Platforms and languages expand continuously — that's release work, tracked above. This is the story.
Who it's for
Built for people who think for a living — researchers, writers, strategists, founders.
05 · Pricing
Own the substrate.
Not a subscription to someone's server.
Every plan is a license to run Monolithos on your own hardware, against your own vault, with your own data never leaving your drive. Compute is metered fairly. Sovereignty is not. Start with seven days of full access — no card required, no commitment, no time limit on what you think or keep.
