What is Vectorize?

Vectorize is an open-source agent memory system designed to enable AI agents to remember user interactions and improve their performance over time. Built with an MIT license and available on GitHub, it addresses the limitations of traditional memory systems by not only storing facts but also learning from mistakes and synthesizing knowledge. Its core capabilities include per-user persistent memory, cross-session context retention, fast memory recall under 100ms, and compatibility with any large language model (LLM). Vectorize’s reflection layer automatically detects patterns and builds judgment, allowing agents to evolve and handle complex tasks collaboratively. It fits developers and teams building intelligent agents that require continuous learning, multi-agent coordination, and long-term user context retention.
