Friday

Friday is an open-source, self-hosted cognitive memory layer that enables AI coding assistants like Cursor, Claude, and GitHub Copilot to persist architecture decisions, schemas, and preferences across sessions. It uses a multi-tier storage engine including semantic memory, vector search, and a knowledge graph, exposed via the Model Context Protocol (MCP) to improve AI assistant context retrieval and reduce token overhead. It includes a live knowledge graph visualization called Neural Studio and supports integration with multiple AI coding tools.
