AI Memory That Never Fades
Your AI assistant forgets everything every session. CxMS fixes that.
No developer should ever have to re-explain their project to an AI.
Battle-tested across 155+ production sessions. Every feature on this page is running in production today, including enterprise deployments. 1,000+ clones of the open-source framework.
The Problem
Every AI coding session starts from zero. Your AI does not remember yesterday's decisions, last week's architecture choices, or why you made that tradeoff three months ago. You re-explain the same context over and over. Enterprise teams lose thousands of hours per year to AI amnesia.
How It Works
You Work With AI
Make decisions, write code, discuss architecture. Business as usual.
CxMS Remembers
Sessions, decisions, context — searchable, persistent, private. All on your machine.
Next Session Picks Up
Your AI knows exactly where you left off. No re-explaining. No lost context.
Features
BM25 Full-Text Search
Find any decision, discussion, or code change from any session. FTS5 with AND, OR, phrase matching, proximity search.
Context Monitoring
Real-time tracking of how much context your AI has used. Automated session state capture before context compaction.
Compaction Recovery
When your AI context window fills up, CxMS saves everything before it is lost. Resume seamlessly in a new session.
Session Lifecycle Hooks
5 lifecycle hooks (SessionStart, PreToolUse, PostToolUse, PreCompact, SessionEnd) that customize AI behavior without touching the model.
Zero Cloud Dependency
Everything stays on your machine. No data sent anywhere. SQLite-backed, zero external dependencies.
Multi-Tool Export
One config generates profiles for Claude Code, Cursor, Copilot, and more. Switch tools without losing your workflow.

FAQ
Does CxMS send my data anywhere?
No. Everything stays on your machine. SQLite database, local files, zero network calls. We never see your data.
Does it work with Cursor/Copilot/other tools?
CxMS works with any AI coding assistant that can read files. The Profile Manager exports configs for Claude Code, Cursor, Copilot, and others.
How is this different from Mem0?
Mem0 sends your data to their cloud servers. CxMS is local-first, patent-protected, and extends to hardware safety (SASM). Same problem, fundamentally different approach.
What happens if I stop paying?
You keep the Core features forever. Pro features deactivate but your data stays — it is your data on your machine.
