- Cross-session persistence
- Fast memory recall
- Works with any LLM
In-Depth Review: What is Vectorize?
Hindsight is an open-source agent memory system that goes beyond retrieval. It learns from mistakes, detects patterns automatically, and builds judgment over time. With per-user memory, cross-session persistence, and fast recall under 100ms, it works with any LLM. Achieved 94.6% on LongMemEval, #1 on BEAM. Install via one command with MCP agents.
Core Features
Per-user memory
Every user gets persistent context. Preferences, history, and decisions stay separate.
Cross-session persistence
Context survives session boundaries. Pick up where you left off, weeks later.
Fast memory recall
Parallel search returns the most relevant memories in under 100ms.
Works with any LLM
Model-agnostic memory layer. Swap LLMs without losing what your agent learned.
Learns from mistakes
When a tool call fails or a user corrects your agent, that becomes an experience. Next time, your agent knows what went wrong.
Detects patterns automatically
The reflection layer synthesizes individual facts into consolidated knowledge. Patterns emerge from data, not from manual tagging.
Builds judgment over time
Your agent doesn't just get more data. It gets better judgment. Curated mental models guide common situations.
Shared context across agents
Agent A learns a user preference. Agent B applies it automatically.
Memory that improves itself
The reflection layer consolidates raw observations into reusable knowledge.
MCP server built in
Your agent gets remember, recall, and reflect tools automatically via the MCP server.

Pros and Cons
Pros
- Open source & MIT licensedFree to self-host with no restrictions, full access to source code.
- Fast memory recallParallel search returns relevant memories in under 100ms.
- Learns from experiencesAgents improve over time by learning from mistakes and user corrections.
- Model-agnosticWorks with any LLM; swap models without losing learned memory.
- Easy integration with MCPOne command setup with MCP-compatible agents like Claude Code or Cursor.
Cons
- Self-hosted requires DockerDeployment depends on Docker, which may not suit all environments.
- Cloud pricing variablePay-as-you-go token usage can become expensive at high scale.
