What is DeltaMemory
DeltaMemory is an innovative solution designed to solve the problem of AI agents forgetting previous interactions. It serves as a cognitive memory layer that allows AI agents to maintain persistent memory across conversations and sessions. The platform offers a streamlined way to add memory capabilities to any AI agent through simple SDK integration, supporting major frameworks like Vercel AI SDK, LangChain, CrewAI, and n8n. With key performance metrics including 89% accuracy on the LoCoMo benchmark, 50ms retrieval latency, and 97% cost reduction compared to raw token reprocessing, DeltaMemory stands as a robust solution for production AI applications.
Key Features of DeltaMemory
DeltaMemory is a cognitive memory layer for AI agents that provides persistent recall, automatic fact extraction, and temporal reasoning capabilities. It offers high accuracy (89% on LoCoMo benchmark), fast retrieval (50ms latency), and significant cost reduction (97%) compared to raw token re-processing. The system compresses conversations, maintains knowledge graphs, and integrates easily with existing AI frameworks while providing full observability and enterprise-grade security features.
Token Compression: 3,714x compression ratio that converts raw conversations into structured facts and knowledge graphs, reducing 26M tokens to 7K tokens
Easy Integration: Simple three-line SDK implementation with native support for popular frameworks like Vercel AI SDK, LangChain, CrewAI, and n8n
Built-in Observability: Complete tracing of memory operations, fact extraction, and salience scores with full visibility for debugging agent behavior
Enterprise Security: SOC 2 and HIPAA-ready architecture with cryptographic ownership of memory graphs and fine-grained consent controls
Use Cases of DeltaMemory
Healthcare Patient Management: Medical AI assistants that maintain persistent patient history, medication interactions, and care preferences across multiple sessions while maintaining HIPAA compliance
Personalized Education: AI tutors that track individual student progress, identify knowledge gaps, and adapt teaching methods based on accumulated learning patterns
Customer Support Enhancement: Support agents that maintain complete customer history, past tickets, and resolutions, eliminating the need to ask repeated questions
Intelligent Sales Management: Sales AI that tracks prospect interactions, objections, and buying signals across multiple touchpoints to inform follow-ups with full relationship context
Pros
High performance with 89% accuracy on LoCoMo benchmark and 50ms query latency
Significant cost reduction (97%) compared to traditional token processing
Enterprise-ready with robust security features and deployment flexibility
Cons
Limited availability (currently only for select design partners and enterprise teams)
Requires integration effort despite simplified SDK
How to Use DeltaMemory
Install DeltaMemory SDK: Install the package using npm: npm i @deltamemory/ai-sdk
Set up environment variables: Configure your DELTAMEMORY_API_KEY and DELTAMEMORY_URL from the dashboard in your environment variables
Initialize DeltaMemory client: Create a new DeltaMemory instance with your API credentials:
const client = new DeltaMemory({
apiKey: process.env.DELTAMEMORY_API_KEY,
baseUrl: process.env.DELTAMEMORY_URL
});
Integrate with AI framework: Import and set up deltaMemoryTools with your preferred framework (Vercel AI SDK, LangChain, CrewAI, or n8n)
Add memory to your agent: Include deltaMemoryTools in your model configuration:
tools: { ...deltaMemoryTools(client, { userId }) }
Ingest conversations: Store conversations using the ingest method:
await dm.ingest('user_123', message)
Access stored memories: The system will automatically extract facts and build knowledge graphs from conversations. These will be available in future interactions with the same user
Monitor and debug: Use the built-in observability tools to track fact extraction, memory recalls, and salience scores through the dashboard
