The memory layer that decides what's worth remembering
Cortex by SKYNETLAB is an innovative hosted semantic memory platform designed to enhance AI systems' ability to remember and reason over data. It connects seamlessly over MCP, allowing AI models like Claude to access a structured, high-quality memory layer that filters redundant information, tracks contradictions, and attributes sources to facts. The setup is remarkably quick, taking just two minutes, and it works effortlessly with any MCP client, making it accessible for a broad range of AI applications. Built with an EU infrastructure and a patent-pending engine, Cortex emphasizes data integrity, transparency, and efficiency, making it ideal for organizations seeking a robust memory solution for their AI tools. Its focus on quality control—rejecting roughly 80% of writes as redundant—ensures that only valuable, non-duplicate information is retained, fostering accurate and reliable AI responses.
