# Why Lattice AI Exists

**Lattice AI is a local-first Digital Brain that keeps your knowledge durable across any AI model.**

**모델은 바꿔도, 내 지식은 남는 로컬 AI 브레인.**

AI models change quickly. A model you use today may be replaced next month, and
the conversation history, project context, decisions, and sources you built
around it can become scattered across tools. Lattice AI exists so the durable
asset is not the model. The durable asset is your Brain.

## The Problem

Most AI products begin with a model and treat your context as temporary prompt
material. That works for short questions, but it fails for long-running work:

- project decisions disappear into old chats;
- documents and notes are disconnected from conversations;
- switching models often means losing useful context;
- graph or database tools expose implementation details before user value;
- cloud-only products make it hard to inspect, back up, or move your knowledge.

## The Lattice Answer

Lattice AI is a local-first private AI memory layer. It keeps conversations,
documents, decisions, relationships, and project history in a Brain that belongs
to the user. Models can be local, cloud, current, or future. The Brain remains.

The graph is real, but it is not the product identity. Product category is
local-first Digital Brain; core capability is a private AI memory layer; UX
metaphor is the Living Brain. Users start with Brain
Chat, memory, topics, relationships, ownership, backup, and graph exploration.
Advanced admin logs, roles, hooks, workflows, Telegram, Brain Network, Docker,
Postgres, and plugin details stay outside the normal user flow.

## Practical Reasons To Use It

- Ask what the team decided last week and see the source.
- Drop in documents and build a searchable personal memory.
- Prepare for a meeting from past notes, project decisions, and files.
- Preserve context when moving from one model to another.
- Export or back up the Brain as an encrypted `.latticebrain` archive.
- Use Korean or English without changing the underlying Brain.
- Avoid fake answers when no model or evidence is available.

## What Lattice AI Is Not

- Not a hosted SaaS by default.
- Not just a model launcher.
- Not just a graph viewer.
- Not a generic dashboard.
- Not a note-taking clone.
- Not a ChatGPT or Claude clone.

Lattice AI is for people who want their knowledge to survive model changes.
