# Lattice AI

**Your model is the voice you use today. Your Brain is the asset you keep.**

**모델은 갈아타도, 내 지식은 내 컴퓨터에 남는 로컬 우선 AI 브레인.**

![v11.4.0 Living Brain walkthrough](output/release/v11.4.0/gifs/v11.4.0-living-brain-walkthrough.gif)

Chat, files, folders, notes, and web pages all flow into one durable knowledge
graph on your computer. Any model — local MLX or cloud — can speak with that
memory. Nothing leaves your machine without explicit consent.

대화·파일·폴더·웹페이지가 전부 내 컴퓨터 안의 지식 그래프로 쌓이고, 어떤
모델이든 그 기억을 이어받아 대화합니다.

## What You Can Do

| | |
| --- | --- |
| **See your Brain's story in time** — a growth curve, an activity heatmap, and each day's story, rewindable to any past moment ![Brain Chronicle](output/release/v11.4.0/screenshots/13-chronicle.png) | **Chat with a Brain that remembers** — every conversation grows durable, source-linked memory ![Brain Chat](output/release/v11.4.0/screenshots/04-brain-chat-home.png) |
| **See how knowledge connects** — a real relationship graph, not a file list ![Memory Graph](output/release/v11.4.0/screenshots/05-memory-graph.png) | **Capture anything** — files, whole folders, notes, screenshots, web pages ![Capture](output/release/v11.4.0/screenshots/06-capture.png) |
| **Automate with review** — agent changes become proposals you approve first ![Review Center](output/release/v11.4.0/screenshots/12-review-center.png) | **Pick a model in one click** — recommended local models for your hardware ![Recommended Models](output/release/v11.4.0/screenshots/02-recommended-models.png) |
| **Watch a file become memory** — three named steps, not a pipeline diagram ![Material to memory](output/release/v11.4.0/screenshots/11-knowledge-journey.png) | **Say how much it may do alone** — one dial in plain words; dangerous actions stay blocked either way ![Settings](output/release/v11.4.0/screenshots/08-system.png) |

## Why Lattice AI

- **Own your memory** — knowledge lives in a local SQLite Brain you can back up,
  export, inspect, and restore (`.latticebrain` encrypted archive).
- **Model-independent** — switch between local MLX models and cloud models
  without rebuilding context from zero.
- **Honest by design** — the Brain tells you when retrieval context is limited,
  when captured pages extracted poorly, and when the vector index is catching up.
- **Safe automation** — automations are consent-first drafts; edits to existing
  content always pass through a reviewable proposal with a diff.

매번 AI에게 프로젝트 맥락을 다시 설명하고 있다면, 지식이 여러 서비스에 흩어져
있다면, 그 기억을 특정 회사가 아니라 내가 소유하고 싶다면 — Lattice AI가 그
브레인입니다.

## Quick Start

```bash
pip install ltcai        # or: npm install -g ltcai
LTCAI                    # then open http://127.0.0.1:4825/app
```

Apple Silicon local models: `pip install "ltcai[local]"`. Desktop app (Tauri)
ships as a dmg on each [GitHub Release](https://github.com/TaeSooPark-PTS/LatticeAI/releases).

First-run flow — wake the Brain, pick the owner, load a recommended model:

## Current Release

The current release is **11.4.0 — Rust Foundation**:

The Rust migration begins — not as a rewrite, but as **working, proven
pieces**, while the Python server keeps serving every product surface.

- **A `rust/` workspace with three crates.** `lattice-core` reads the
  same `knowledge_graph.sqlite` (read-only, WAL) and carries a
  bit-for-bit port of the local hash embedder. `lattice-retrieval` is the
  native hybrid/keyword/vector engine — proven against committed Python
  goldens at **75/75 exact parity, zero epsilon**, with a bidirectional
  contract: a Python test suite re-runs the same goldens so neither side
  can drift silently. `lattice-host` is the worker supervisor (HTTP
  `/health` gating, crash auto-restart with backoff, graceful shutdown,
  unified port selection) plus a loopback-only gateway: `/host/*` status,
  native `/rust/search/*`, and a streaming reverse proxy for everything
  else — an opt-in front door, with 194 Rust tests behind it.
- **The desktop shell rides the new foundation.** The Tauri `main.rs`
  shrank from 451 to 149 lines by consuming `lattice-host`; its five IPC
  commands keep their exact contracts, a candidate-resolution
  priority-order bug is fixed, and the TCP probe became a real health
  check.
- **The same discipline, extended.** CI gained a dedicated `rust` job
  (fmt, clippy `-D warnings`, tests); the 1,000-line file ceiling now
  covers `*.rs`; the version bump keeps the Rust workspace in lockstep
  (25 synchronized targets). The full migration roadmap lives in
  [docs/v11.4.0_RUST_FOUNDATION_PLAN.md](docs/v11.4.0_RUST_FOUNDATION_PLAN.md).

All of it lands with the floor intact: **6,643 Python + 1,761 frontend
tests at 100.00% statement and branch coverage, 194 Rust tests**, mypy
and clippy clean, verified on macOS 3.14 and a fresh-resolve python 3.11
environment.

Release notes: [RELEASE.md](RELEASE.md) · Full history: [docs/CHANGELOG.md](docs/CHANGELOG.md)

Expected artifacts for 11.4.0 release must use exact filenames:

- `dist/ltcai-11.4.0-py3-none-any.whl`
- `dist/ltcai-11.4.0.tar.gz`
- `ltcai-11.4.0.tgz`
- `dist/ltcai-11.4.0.vsix`
- `src-tauri/target/release/bundle/dmg/Lattice AI_11.4.0_aarch64.dmg`

Do not use wildcard artifact uploads. Package registry publishing remains owner-run.

## Architecture At A Glance

FastAPI on localhost is the source of truth; the React/Vite frontend and the
Tauri desktop shell sit on top; the independent `lattice_brain` package owns
the graph, memory, ingestion, and portability. Local-first by default — cloud
calls, downloads, Telegram, and update checks are opt-in.

See [ARCHITECTURE.md](ARCHITECTURE.md) for details and
[docs/DEVELOPMENT.md](docs/DEVELOPMENT.md) for the developer workflow
(`npm install && npm run dev`, validation via `npm run lint`,
`npm run test:unit`, `npm run test:visual`).

## Known Limitations

- External package registries are owner-published and can lag behind GitHub.
- PostgreSQL/pgvector is optional scale/migration tooling. SQLite remains the
  live local Brain store in 10.3.0.
- Docker, model downloads, cloud model calls, Telegram, Brain Network, and
  update checks require explicit user action.
- Conversation does not fabricate answers when no model is loaded. Agent and
  workflow simulation without a loaded LLM is deterministic and LLM-free (it
  does not call a model) — labeled as such, never presented as autonomous
  model success.
- Some backend-generated messages (for example the Postgres DSN notice) are
  produced server-side in English and are shown as-is; server-side i18n is not
  part of 10.3.0.
