NENO is a note-taking app that helps you create your personal knowledge graph.

Relatrix is a note taking app where you can save files and write chronologically organized opinion cards (of different types). Group these cards using tags and draw direct links between related ideas across your library, all visualized in an interactive 3D space called Relatrix. Built for privacy, all data remains strictly offline and encrypted.

Persistent memory for AI agents. Extract once, recall forever.

The Personal Knowledge Graph You Didn’t Know You Already Wrote

Vellis — open-source context graph engine for AI agents: typed, local-first memory with explicit schema, validated change, deterministic query, migration, snapshots, replay, and audit. MCP-native. Apache-2.0.

An open-source AI that quietly remembers who you are — in plain markdown you fully own. Works with Claude Code, Codex CLI, opencode, and any other agent that reads AGENTS.md.

LIFENEXUS — A Personal Memory Engine that connects scattered digital traces into a searchable knowledge graph, life timeline, and intelligent insights.

A personal knowledge graph for Claude that survives across sessions, devices, and tools. Neo4j + semantic embeddings, OAuth-secured, single-user-by-default but multi-tenant-ready.

A four-layer knowledge distillation system inspired by Karpathy's take on personal knowledge bases. macOS/Linux/Windows, optional LLM fallback.

Capture-first research notebook (a modern commonplace book / second brain). Drop a topic in one line; Neemee researches it in the background and files it back as a structured, connected brief that gets smarter as it grows.

Import selected Chinese personal-data exports into SQLite, link entity aliases and query simple aggregates with row-level source references.

Nexus is a personal life knowledge graph OS that models people, relationships, assets, events, and places as a unified graph. It enables timeline tracking, smart queries, and AI-powered insights with fine-grained RBAC for secure sharing and collaboration.

Lattice — mobile ontology datastore for AI agent knowledge bases: an encrypted, on-device hierarchical knowledge graph (personal agent memory) with granted, logged access. Rust → WebAssembly in the browser (Web Worker + OPFS). Part of Salt, the end-to-end encrypted AI chat app.
