# Aristra AI > Aristra is the universal memory layer for AI. It builds cognitive, relational memory across ChatGPT, Claude, Gemini, and any MCP-compatible agent — so your AI actually remembers how you think, not just what you've typed. Aristra Labs is building the infrastructure for persistent AI memory. Unlike vector search or basic fact storage, Aristra uses relational reasoning and a decay algorithm to maintain a living context graph that gets sharper over time. It works across every major AI platform via the Model Context Protocol (MCP). ## Core Pages - [Home](https://aristralabs.com): Product overview, features, and how Aristra works - [About](https://aristralabs.com/about): Company background, founding story, and mission - [Join the Beta](https://aristralabs.com/beta): Sign up for early access to Aristra ## Blog - [Blog](https://aristralabs.com/blog): Latest articles on AI memory, cognitive computing, and product updates - [RSS Feed](https://aristralabs.com/blog/rss.xml): Subscribe to new posts ## Key Concepts - [Context Graph](https://aristralabs.com): Aristra maps relationships between ideas, decisions, and context — not just keyword similarity - [Decay Algorithm](https://aristralabs.com): Old irrelevant memories fade while important context surfaces automatically - [MCP Bridge](https://aristralabs.com): Connect any MCP-compatible agent to your memory layer with a single config block ## Integrations - Works with: ChatGPT, Claude, Gemini, Slack, WhatsApp, Browser Extension, REST API - Protocol: Model Context Protocol (MCP) — zero-code integration for any compatible client - MCP Endpoint: mcp.aristra.ai ## Company - Company: Aristra Labs, Inc.
