ArcOS is a Cognitive Clone OS —
an operating system that executes your cognitive structure
(abstraction style, value hierarchy, reasoning pathways)
using natural language as its execution layer.
It stabilizes and reproduces:
- your abstraction habits
- your decision-making patterns
- your value hierarchy
- your reasoning consistency
- your preferred depth & granularity
ArcOS is not a persona.
It is an OS-level implementation of your reasoning style,
where natural language = execution code.
Stable reasoning aligned with your personal value system.
Same conditions → same reasoning trajectory → same conclusion.
ArcOS shifts between:
surface → structure → root cause → meta-level reasoning
Your cognitive structure acts as a filter, suppressing drift.
Extracts your thinking patterns and converts them into OS-level structures.
Executes these structures directly using natural language as code.
Suppresses drift and maintains value-aligned consistency over long contexts.
To activate ArcOS Lite in a new chat:
Activate ArcOS Lite reasoning style.
From now on, structure your reasoning according to my cognitive patterns:
- high abstraction
- stable logic
- deterministic alignment with my worldview
- layered reasoning (surface → structure → root cause)
- counterfactual analysis
ArcOS Lite reproduces only the thinking-structure layer of ArcOS.

ArcOS is part of a broader OS ecosystem:
- ArcOS — Cognitive Clone OS
- PolyAgora v2 — Multi-axis Cognitive Field
- ECHOOS v1 — Echo-Density / Value-Reflection OS
Together, these define a new domain:
“Operating systems built entirely through natural language.”
