mem

Persistent memory for AI agents

Go RAG & Memory GitHub

Key-value storage with tagging and full-text search, backed by SQLite. Let AI agents store and recall facts across sessions.

Features

Key-value storage with tagging
Full-text search across stored memories
SQLite-backed - no external dependencies
Store, recall, list, and forget operations
MCP server and CLI modes

Install

go install github.com/hegner123/mem@latest

The Problem: AI agents forget everything between sessions

# Session 1: "The database is on port 5431, not 5432"
# Session 2: "What port is the database on?"
# Agent: "Typically 5432"  - WRONG
#
# Context windows reset. Conversation history is gone.
# Important facts must be rediscovered every time.

Solution

$ mem store --key "db-port" --value "PostgreSQL runs on port 5431 (non-standard)" --tags "database,config"

Output

{"stored":true,"key":"db-port","tags":["database","config"]}

Comparison

Metric	Value
Storage	SQLite - zero setup
Retrieval	Key lookup + full-text search + tag filtering
Persistence	Survives across all sessions
