CEM888
Take control of your AI runtime.
Your data. Your state. Your machine.
CEM888 is a local-first AI runtime that keeps one authoritative record of what is true across every model and app you use, and gives every important action a verifiable receipt. It runs on your machine, so your data and state stay yours, and it is model-agnostic — use the best model for the job while CEM888 keeps the continuity.
Authoritative State
One record of what's true across every model and app. No more conflicting context.
Model-Agnostic
Use the best model for the job. CEM888 keeps the continuity.
Verifiable Actions
Every important action leaves a verifiable receipt. You can trust what happened.
Local-First
Runs on your machine. Your data stays yours. Higher control, lower cost.
STATE DECIDES WHAT IS TRUE. MODELS DECIDE WHAT TO DO ABOUT IT.
