Experience Layer for AI
Current AI agents lack persistent memory, making them ineffective for tasks requiring personal or organizational context. The solution is a third layer—experience—that captures, processes, and consolidates an agent's interactions over time. CortexDB provides this experience layer through a five-stage memory cycle and five layered data model, enabling intelligent, auditable, and trustworthy AI agents.
- ▪AI agents today have no persistent memory, limiting their usefulness in personalized or organizational contexts.
- ▪CortexDB introduces a memory cycle—Capture, Extract, Reconcile, Forget, Consolidate—to create a dynamic experience layer for AI.
- ▪The system organizes memory into five layers: Events, Episodes, Facts, Beliefs, and Understanding, enabling traceable, probabilistic reasoning.
- ▪CortexDB achieves state-of-the-art results on two major AI memory benchmarks: LongMemEval-S and LoCoMo.
- ▪Unlike most AI memory systems, CortexDB supports evidence-based beliefs and can answer 'why do you think that?' via a dedicated API endpoint.

Opening excerpt (first ~120 words) tap to expand
The missing third layerToday's AI agents are amnesiacs. Open ChatGPT, tell it your name, log out, come back tomorrow — it has no idea who you are. For a chatbot that's annoying. For an agent — one that books travel, manages a customer pipeline, debugs production systems — it's broken.People have tried to paper over this by stuffing more text into the prompt. The prompt is a clipboard, not a memory. You can't enforce "delete this customer's data" on a clipboard. You can't audit who saw what. You can't answer why do you think the deal is at risk? from a clipboard.A real AI agent needs three layers, stacked together:Layer 1IntelligenceThe LLM: reasoning, language, planning.
