Product Overview

The runtime that makes AI remember — and stay in bounds

Yohanun sits between your application and any LLM — OpenAI, Anthropic, Google, DeepSeek, or local models. It's what lets you hand AI real responsibility — client files, personal history, actions with consequences — because nothing gets recalled, revealed, or done that the platform hasn't already cleared.

Three components. One semantic runtime.

Yohanun provides the essential infrastructure that every intelligent system needs: memory that persists, rules that explain, and context that evolves.

Memory Layer

Hybrid vector + graph storage that survives restarts, learns from patterns, and builds semantic understanding over time.

Cross-session persistence
Semantic search & relationships
Contextual recall & learning

Rules Engine

Declarative business logic that creates explainable, auditable decisions. Define rules once, trust them everywhere.

Permission-aware logic
Audit trails & compliance
Explainable judgment

Context Manager

Intelligent context weaving that understands what matters when. Right information, right time, every time.

Temporal understanding
Multi-modal context weaving
Contextual awareness
Model Agnostic

Works with any LLM. No vendor lock-in.

Yohanun doesn't replace your LLM — it makes it smarter. Whether you're using GPT-5, Claude, Gemini, DeepSeek, or running local LLMs, Yohanun provides the same semantic infrastructure.

Switch models without rebuilding your memory. Change providers without losing context. Build once, run anywhere.

New: Governance Core

Governed by design. The model is never the gatekeeper.

The result: leaks that can't happen, agents that can't overreach, and an audit trail that answers your compliance team's questions before they're asked. All enforced by the platform — the model is never the gatekeeper.

Clearances

Platform-owned clearance ledger controls who can see what. Labeled memory, conflict-of-interest checks, and instant revocation — enforced on every read.

Mandates

Agents act up to an explicit limit — and no further. Anything over the line escalates to a human decision queue. Commits fail closed; every action is audited.

Learning Loop

Report outcomes — success, failure, correction — and they become retrievable lessons. Memory that helped ranks higher; memory that hurt ranks lower.

Simple integration. Powerful results.

Add semantic intelligence to your existing AI workflows in minutes, not months.

# One REST call. Memory, governance, and rules applied by the platform.

# The response includes the answer, the memory sources it drew on,
# and temporal context — every source one your principal was cleared to see.
# Streaming (SSE) and WebSocket endpoints take the identical request.
