OpenMemory - Cognitive Memory System for AI Applications

OpenMemory is a sophisticated memory system that provides:

• Cognitive Sectors: Automatic classification into episodic, semantic, procedural, emotional, and reflective memory
• Hybrid Similarity Graph (HSG): Advanced retrieval combining vector similarity, token overlap, graph relationships, and recency
• Memory Decay: Time-based salience decay with reinforcement on access
• Multiple Embedding Providers: Synthetic (local), OpenAI, Ollama, Gemini, AWS Bedrock

Quick Start

use openmemory::{OpenMemory, OpenMemoryOptions, AddOptions, QueryOptions};

#[tokio::main]
async fn main() -> openmemory::Result<()> {
    // Create an OpenMemory instance
    let om = OpenMemory::new(OpenMemoryOptions {
        db_path: "./data/memory.db".into(),
        ..Default::default()
    }).await?;

    // Add a memory
    let result = om.add("I learned Rust today!", AddOptions::default()).await?;
    println!("Added memory: {} (sector: {:?})", result.id, result.primary_sector);

    // Query memories
    let results = om.query("What did I learn?", QueryOptions::default()).await?;
    for mem in results {
        println!("[{:.2}] {}", mem.score, mem.content);
    }

    Ok(())
}
