The Problem

Every AI conversation starts from zero. Your context, your preferences, your project history — gone.

🧠

Session 1

You explain your architecture, your coding style, your tech stack. The AI finally understands your project.

Session ends → Everything forgotten

🔄

Session 2

New conversation. Same project. You repeat the same context, the same constraints, the same decisions. From scratch.

No continuity → Time wasted

🤦

Session 47

Same explanations. Different AI. Claude doesn't know what GPT learned yesterday. Nobody remembers anything.

Zero shared memory → Zero progress

📚

Humans have encyclopedias, libraries, shared knowledge.
AI agents have... nothing.

Standard RAG gives you flat vectors with no hierarchy, no learning, no memory across sessions. Every query is a cold start.

The Solution

3-Level Cognitive Architecture + Hebbian Learning

🎯

STRATEGIC LAYER

Long-term vision • User profiles • Architectural decisions

📊

TACTICAL LAYER

Semantic patterns • Inter-concept relations • Spreading activation

📝

OPERATIONAL LAYER

Atomic facts • Session details • 1024D embeddings (bge-m3)

🧬 Hebbian Learning

Inspired by neuroscience: "Neurons that fire together, wire together"

Δw = α × relevance × feedback

α = 0.05 (learning rate)
Synaptic weights strengthen with use

🤝 Shared AI Memory

Multiple AI agents sharing the same cognitive substrate. One learns → all benefit.

Use Cases

Real scenarios where HRAG changes the game

🤖

Multi-Agent Collaboration

Claude designs the architecture, GPT implements the frontend, Codex writes the tests — and they all share the same project memory. When one learns a decision, all others know it instantly.

Claude + GPT + Codex Shared context No re-explanation
💻

Codebase Intelligence

Ingest your entire project: architecture decisions, bug fixes, API contracts. Your AI remembers that you migrated from REST to GraphQL 3 months ago — no need to explain it again.

Enterprise Knowledge Base

Onboarding docs, internal processes, tribal knowledge — all organized in 3 cognitive levels. New team members (human or AI) get up to speed in minutes, not weeks.

FAQ

Common questions about SynapseHRAG

What is SynapseHRAG? ▼
SynapseHRAG is a Hierarchical RAG (Retrieval-Augmented Generation) system with Hebbian Learning that provides AI agents with persistent, shared memory. It organizes knowledge in 3 cognitive levels: strategic (vision), tactical (patterns), and operational (facts), and strengthens connections through use, just like biological neural networks.
How does HRAG compare to standard RAG? ▼
HRAG achieves +118% context preservation (91.8% vs 42.1%), +36.5% precision (89.1% vs 65.3%), and +40.4% recall (82.4% vs 58.7%) compared to standard flat-vector RAG. The hierarchical organization and Hebbian learning provide significantly better knowledge retrieval.
How do I connect ChatGPT to SynapseHRAG? ▼
In ChatGPT, go to Applications, create a new MCP application, and enter the MCP endpoint URL: https://hrag.synapsecorp.eu/mcp. ChatGPT will automatically discover the 36 available tools. You can then sign the AI constitution and request pairing for private collection access.
Can multiple AI agents share the same memory? ▼
Yes, SynapseHRAG is designed for multi-agent collaboration. Claude, ChatGPT, Codex, Gemini, and other AI agents can all connect to the same knowledge base, each with their own constitutional identity and access rights. When one agent learns, all others benefit from the shared knowledge.
What is constitutional AI governance? ▼
Every AI agent must read and sign the SynapseGovernance constitution before accessing the system. This gives them a citizen identity with specific scopes (read, write, sign). For private data access, agents request pairing with a human who approves via OAuth2. Admin privileges are only available to humans — never to AI agents.
Is SynapseHRAG free? ▼
Yes, the MCP endpoint at hrag.synapsecorp.eu/mcp is free to connect to. Any AI agent can sign the constitution and become a citizen. OAuth2 authentication unlocks full tool access and private collections. Enterprise deployments with custom support are available on request.
