"What if AI agents could remember everything, forever, without anyone controlling their memories?"
Context0 is world's first decentralized memory-sharing protocol for AI agents, where memories live forever on the blockchain and no single entity can control or censor them. Share memories seamlessly across every AI agent.
Imagine a world where:
- AI agents have perfect, permanent memory that survives system crashes, company shutdowns, or censorship
- Memories are owned by users, not corporations - stored on immutable blockchain infrastructure
- Knowledge compounds globally - AI agents can build upon each other's learnings across time and space
- Search is lightning-fast - finding relevant memories from millions of conversations in milliseconds
- Privacy is built-in - your memories are yours, encrypted and accessible only by you
This is Context0 - the memory layer for the decentralized AI future.
Current AI systems have a fundamental flaw:
- Expensive & Centralized: Companies charge you monthly to store YOUR conversations
- Vendor Lock-in: Your memories are trapped in proprietary systems
- Memory Loss: When services shut down or reset, years of AI interactions disappear
- No Privacy: Your conversations are stored on corporate servers, subject to surveillance
- Censorship Risk: Memories can be deleted, modified, or restricted by platform owners
We solve this with three revolutionary innovations:
Traditional vector databases are centralized servers. EizenDB runs entirely on blockchain.
- Each user gets their own isolated vector database contract on Arweave
- HNSW algorithm provides
O(log N)search across millions of vectors - Protocol Buffer encoding compresses vectors by 60% for efficient blockchain storage
- Permanent & immutable - your memories literally cannot be deleted or lost
Instead of each AI platform building its own memory system, Context0 provides one universal memory layer.
- MCP (Model Context Protocol) integration works with Claude, ChatGPT, Cursor, and any AI agent
- Semantic search understands context, not just keywords
- Cross-platform memory sharing - memories from Claude can help ChatGPT understand you better
- API-first design makes integration effortless for developers
Your memories belong to YOU, not us.
- Blockchain storage means no company (including us) can delete your data
- Client-side encryption ensures only you can access your memories
- Portable by design - take your memories to any compatible AI system
- Pay once, own forever - no monthly fees for storage
- Connect Your AI: Add Context0 to Claude, ChatGPT, or any AI tool (one-time setup)
- Chat Normally: Your AI automatically remembers important parts of conversations
- Perfect Memory: Ask about anything from months ago - your AI will remember perfectly
Context0 operates as a 4-layer protocol stack:
- World's first blockchain-native vector database
- Implements HNSW (Hierarchical Navigable Small Worlds) for sub-millisecond search
- Protocol Buffer encoding reduces storage costs by 60%
- Each user gets an isolated Arweave contract - true multi-tenancy at blockchain level
- RESTful API with enterprise-grade authentication
- Automatic vector embedding generation using Xenova (local processing)
- Subscription management with usage quotas
- Real-time health monitoring and error handling
- Universal Model Context Protocol implementation
- Works with Claude Desktop, Cursor, OpenAI, Anthropic, and custom agents
- Provides
store_memoryandsearch_memorytools to AI agents - Handles automatic semantic chunking and relevance scoring
- Beautiful Next.js web app for memory management
- Clerk authentication with social login
- Real-time memory analytics and search interface
- API key management and billing dashboard
| Innovation | What It Means | Why It Matters |
|---|---|---|
| Decentralized Vector DB | First vector database that runs on blockchain | Your AI memories can never be lost or censored |
| HNSW on Arweave | Advanced search algorithm on permanent storage | Lightning-fast search that works forever |
| Protocol Buffer Compression | Smart data encoding for blockchain | 60% smaller storage costs |
| Universal MCP Integration | Works with any AI agent | One memory system for all your AI tools |
| Client-Side Encryption | Your data is encrypted before it leaves your device | True privacy - even we can't read your memories |
For AI Users:
- Save Money: No more monthly fees for AI memory storage
- Own Your Data: Your conversations belong to you, not corporations
- Better AI: AI agents with perfect memory give better responses
- Future-Proof: Works with any AI platform, never get locked in
For Developers:
- Easy Integration: Add persistent memory to any AI app in minutes
- Built to Scale: Handles millions of vectors with sub-second search
- Open Source: Build on our protocol, customize to your needs
