CEX
Memory Tools Skills Policies

01 / The idea

Intelligence is the start.
Experience gives it a history.

Bring your own intelligence. CEX gives it somewhere to build on what came before: remembered context, lessons from past work, reusable skills, and goals that carry into tomorrow. Your next session has a history to draw on.

That is what we mean by an AGI harness: the persistent system around your model, with memory, tools, and room to act under your control. The harness provides continuity; the model supplies the intelligence.

02 / The system

Experience worth keeping.
A system to carry it forward.

Remember the work. Reuse what helped. Keep moving toward what matters.

01 Persists

A history to build on.

Keep useful context and lessons from past work. Bring them back when they matter, so your intelligence can draw on experience as you work together.

02

Give ideas a way to act.

Search, browse, read, write, and build. Connect intelligence to real work with the access you approve.

03

Let useful experience become a skill.

Keep a method that worked as a reusable skill. Give the next task a starting point from the last.

04

Give it something to work toward.

Keep goals, progress, and next steps beyond a single conversation. Return to the work without rebuilding the brief.

05

Room to act. Boundaries you set.

Choose what CEX may do and when it must ask. Keep its permissions and your rules visible as the work grows.

06

A place for the work to grow.

Keep files, previews, edits, and project conversation together. Build on a project over time, not just a single answer.

03 / Your intelligence

Change the model.
Keep the experience.

Your model can change without taking your history with it. Run a local model or connect a provider while keeping saved memory, skills, goals, and project state in CEX.

  • 01 Local models through the runtime you control
  • 02 Provider models with your own credentials
  • 03 Shared memory, skills, and project history around either
