Originally launched as an AI second-brain bookmark manager, Supermemory has evolved into an infrastructure engine providing persistent memory and continual learning for AI agents. It extracts and updates context from documents, chats, and URLs into a vector-graph database, dynamically injecting relevant memories into model prompts via API, MCP, or native integrations.

What it's for

  • Provide persistent context and continuous memory across AI agent sessions
  • Connect AI assistants like Claude Desktop, Cursor, and ChatGPT via Model Context Protocol (MCP)
  • Index and retrieve knowledge from complex documents, raw data, and web URLs for LLMs
  • Self-host an air-gapped vector-graph memory layer for enterprise AI workflows

Features

  • Vector-graph database architecture that maps interconnected memories over time
  • Learner-1 model that continuously extracts, merges, and updates context
  • Real-time token injection into agent context windows
  • Model Context Protocol (MCP) support and direct plugins for Cursor, Claude, and ChatGPT
  • Advanced document parsing with OCR and diagram extraction for PDFs
  • Deployable via cloud API, self-hosted Docker, VPC, or local environments
  • Enterprise compliance including SOC 2, HIPAA, and GDPR alignment

Pricing

Freemium. Free tier available; paid Pro, Max, Scale, and Enterprise plans offered.
