Hindsight 1.0 + Memlake

Hindsight 1.0 + Memlake is an open source agent memory system that learns from mistakes and experience over time.

Hindsight 1.0 + Memlake is an open source agent memory layer that lets agents learn from mistakes and user corrections rather than just storing static facts. A reflection layer synthesizes individual facts into consolidated knowledge, building curated mental models for common situations. It provides persistent context that survives session boundaries with parallel search returning relevant memories in under 100ms. It works as a model-agnostic layer supporting Python, TypeScript, or Go, over MCP or plain HTTP, and integrates with coding agents like Claude Code, Cursor CLI, and Copilot CLI. Users can self-host the MIT licensed software using Docker, use Hindsight Cloud with pay-as-you-go token usage billing, or deploy Hindsight Enterprise in a private cloud.
