Your
Second Brain
Lives in Your Infrastructure
Personal knowledge graph and company-wide Living Encyclopedia. Two-level knowledge management for individuals and the enterprise 100% on-premise, zero data leakage.
Two Levels of Knowledge Intelligence
The Second Brain Agent operates at two complementary levels personal cognitive augmentation and collective enterprise memory both powered by the same sovereign AI core.
Personal Knowledge Graph
Each collaborator builds their private knowledge graph notes, insights, documents, decisions enriched autonomously by the LLM with semantic links, without exposing private content to the organization.
- Semantic auto-tagging of personal notes
- Private graph stays local to user
- LLM-powered concept extraction
- Timeline-aware knowledge versioning
Company Living Encyclopedia
The organizational layer aggregates validated knowledge from all contributors into a living, evolving enterprise encyclopedia structured, searchable, and traceable to each contributing expert.
- Collective knowledge aggregation
- Cross-domain concept linking
- Expert attribution & traceability
- Continuous evolution without overwrites
What the Second Brain Can Do
Four core capabilities that transform how your organization captures, links, and evolves knowledge.
Personal knowledge graph
Every note, document, and decision becomes a node in your personal semantic graph queryable, linkable, and versioned.
Company Living Encyclopedia
The organization's collective knowledge, continuously updated and never overwritten always traceable to the expert who contributed it.
LLM-powered auto-linking
The on-premise LLM automatically discovers semantic relationships between concepts, surfacing unexpected connections across domains.
Bi-temporal graph evolution
Every knowledge node carries two time dimensions when the fact was true in the world, and when it was recorded enabling historical replay and time-travel queries.
Personal file upload
Upload any document PDF, Word, CSV, or image directly into your personal knowledge space. Files are semantically indexed, auto-tagged, and linked to graph nodes, stored encrypted on-premise.
Knowledge bridge mapping
Visualize the semantic bridge between your private knowledge nodes and the company encyclopedia. Shared tags and auto-links reveal how your individual insights connect to collective enterprise knowledge.
SME expert corrections
Subject-matter experts formally annotate any knowledge graph entity recording original vs. corrected values, justification, and confidence score. Every correction is attributed, timestamped, and versioned.
GGUF Local Model Export
Export any fine-tuned model to GGUF format for fully air-gapped, on-premise inference via llama.cpp zero public-cloud dependency, zero data leakage.
From Note to Enterprise Knowledge
A continuous four-step loop transforms individual insights into organizational intelligence.
Capture
Collaborators capture notes, decisions, and insights in their private workspace through any connected application or API.
Enrich
The on-premise LLM extracts concepts, detects entities, and auto-links new nodes to the existing personal knowledge graph in real time.
Validate & Elevate
Validated insights are selectively elevated to the company Living Encyclopedia, preserving author attribution and validation timestamps.
Evolve
The bi-temporal graph records when facts change enabling time-travel queries, historical analysis, and knowledge drift detection.
Your Knowledge Never Leaves Your Infrastructure
The Second Brain Agent is deployed entirely on-premise. The LLM, the graph database, and all knowledge nodes reside within your security perimeter. Nothing is sent to external APIs.
- Sovereign LLM (Kimi K3 via ACP)
- Kubernetes-native deployment
- Vault-encrypted knowledge store
- Keycloak RBAC per-node access control
- Zero telemetry to external services
