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.
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  |
Chat with a Brain that remembers — every conversation grows durable, source-linked memory  |
See how knowledge connects — a real relationship graph, not a file list  |
Capture anything — files, whole folders, notes, screenshots, web pages  |
Automate with review — agent changes become proposals you approve first  |
Pick a model in one click — recommended local models for your hardware  |
Watch a file become memory — three named steps, not a pipeline diagram  |
Say how much it may do alone — one dial in plain words; dangerous actions stay blocked either way  |
Why Lattice AI
- Own your memory — knowledge lives in a local SQLite Brain you can back up,
export, inspect, and restore (
.latticebrainencrypted 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
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.
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-corereads the sameknowledge_graph.sqlite(read-only, WAL) and carries a bit-for-bit port of the local hash embedder.lattice-retrievalis 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-hostis the worker supervisor (HTTP/healthgating, 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.rsshrank from 451 to 149 lines by consuminglattice-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
rustjob (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.
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 · Full history: docs/CHANGELOG.md
Expected artifacts for 11.4.0 release must use exact filenames:
dist/ltcai-11.4.0-py3-none-any.whldist/ltcai-11.4.0.tar.gzltcai-11.4.0.tgzdist/ltcai-11.4.0.vsixsrc-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 for details and
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.
