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.
Free, local AGI harness
CEX is a free, local AGI harness for the model you choose. Give it memory, tools, and the continuity to accumulate experience, learn from past work, and grow with you.
Free to use · Local by design · Proprietary
01 / The idea
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
Remember the work. Reuse what helped. Keep moving toward what matters.
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.
Search, browse, read, write, and build. Connect intelligence to real work with the access you approve.
Keep a method that worked as a reusable skill. Give the next task a starting point from the last.
Keep goals, progress, and next steps beyond a single conversation. Return to the work without rebuilding the brief.
Choose what CEX may do and when it must ask. Keep its permissions and your rules visible as the work grows.
Keep files, previews, edits, and project conversation together. Build on a project over time, not just a single answer.
03 / Your intelligence
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.
Your harness, workspaces, and saved memory live on your machine. Outside models and services receive the content you send to them.
Use CEX for personal or commercial work at no charge. Your model or provider may have its own costs. Your work stays yours; CEX remains proprietary.
Start with the essentials. Open advanced controls only when you need them.
