Your AI forgot everything again.
Every session. Every project. Every time. You re-explain the same architecture, repeat the same rules, watch it make the same mistakes you corrected yesterday.
CxMS Pro is persistent AI memory that actually persists.
Works with Claude Code, Cursor, Windsurf, GitHub Copilot, Cline, Continue.dev, Zed, Amazon Q
Sound familiar?
“All the damn time I am annoyed I have to re-tell my LLM a piece of info I have already told it.”
— Developer, Hacker News
“My AI feels like it's far gone in dementia.”
— ChatGPT Plus subscriber
“Explaining your project's core logic for the fifth time in a day.”
— DEV Community
Developer trust in AI accuracy dropped from 43% to 33% in one year. Cursor built a memory feature and removed it. Copilot expires your memories after 28 days.
What changes with CxMS Pro
Not a chat history. Not a vector database. A structured memory system with audit trails, authority enforcement, and governance built in.
Your corrections actually stick
Tell the AI once. It learns permanently. Corrections persist across sessions, across compaction events, across model updates. You teach it once. It remembers forever.
See what your AI actually knows
Other tools store memory in a black box. CxMS Pro stores it in files you can read, edit, and control. If the AI is wrong, you fix it. If you want it to forget, you delete it.
Stop paying for the same tokens twice
Without persistent memory, every session re-loads the same context. CxMS Pro reduced startup context from 29% to 3% of the context window. More room for actual work.
Every decision leaves a trail
When the EU AI Act takes full effect August 2, 2026, you'll need auditable AI decision records. CxMS Pro generates these natively. Not a bolt-on. It's how the system works.
How it works
Install
Run node install.mjs in your project. The installer auto-detects your AI assistant, selects the right context profile, and configures everything. Two minutes.
Work normally
CxMS Pro runs in the background. It learns from your conversations, extracts preferences and decisions, detects contradictions, and consolidates knowledge over time.
It gets smarter
Every session builds on the last. Corrections promote to core knowledge. Stale data decays. Contradictions surface for resolution. The longer you use it, the sharper it gets.
Not another memory plugin
Memory architecture modeled on how human cognition works. Not a flat list. Not a vector search. A confidence-weighted, contradiction-aware memory system with 16 patents pending.
Confidence Tiers
Memories earn trust over time. New learnings start as Recent and promote to Core through repeated confirmation. Your AI knows what it's certain about and what's still unverified.
Emotional Weighting
Corrections stick harder than trivia. Safety-critical information resists decay. The system doesn't treat all memories equally, because they aren't equal.
Contradiction Detection
When two memories conflict, CxMS preserves both and flags the conflict. No silent overwrites. No lost context. The AI knows when it has conflicting information and tells you.
Automated Consolidation
Raw session data merges into patterns, patterns promote to confirmed knowledge, stale data decays gracefully. The longer you use it, the more refined the memory becomes.
Where CxMS Pro fits in the stack
CxMS Pro AI is scaffolding for your existing AI coding CLI. It works through the host CLI's hook system (PreToolUse, PostToolUse on Claude Code; equivalents on others). Hooks fire synchronously before sensitive write actions, blocking the agent if it hasn't verified its claims against source-of-truth files in the current session. Context gets injected at session start. Memory persists in plain markdown files you control.
That's the strongest memory scaffolding possible from outside the agent loop. But the loop itself still belongs to the host CLI. The agent can still ignore retrieved context in its reasoning. The gate blocks specific actions, not the underlying agent step.
For most users, that's enough. The bulk of what makes AI coding assistants forget things is missing context, not active disregard. CxMS Pro AI fixes the context part and gates the write part.
For users who want memory consultation enforced (not just suggested), the next layer is CxMS Agent. OpenCxMS's own coding agent, running its own loop, where the gate becomes enforcement instead of scaffolding.
Same Cortex memory engine. Same KMAP refinement. Same plain-markdown files. Different layer of intervention. CxMS Agent is in development. Read the architecture →
