ltcai 9.9.2

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

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

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	Stay in control — audit, roles, retention in a separate admin surface

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

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 9.9.2 — Artifact Trust:

• A clean core. The historical repo-root compatibility shims are gone (only server.py remains for uvicorn server:app); packaging ships exactly the latticeai.* / lattice_brain.* packages, and a legacy debt gate in npm run lint plus a dedicated test suite keep the root clean for good.
• Your first five minutes matter. A guided "First 5 minutes" card on the empty Brain home walks a new user through asking a first question, adding a first file or note, and seeing what the Brain learned — wired to real features, with progress that persists and a briefing that loads immediately.
• Proactive intelligence you can actually see. Today's briefing now lives on the Brain home instead of a double-collapsed drawer, and Cmd+K opens with proactive quick actions (open briefing, review pending items, ask the Brain) before you type a single letter.
• Review Center at product quality. Proposal cards translate risk and change class into human language, frame diffs with file targets and honest truncation counts, tuck raw IDs into a "Technical details" disclosure, and every approve/reject failure shows a friendly message first.
• Errors that speak your language. The API error pipeline is localized (ko/en): timeouts, unreachable-service, and backend failures produce plain, helpful copy instead of raw statusText or English literals, across chat, admin, care, and intelligence panels.
• Scenario-first tests, smaller evidence footprint. 37 version-named test files were renamed to behavior-named suites, and output/release/ now keeps only the newest three evidence sets (~70MB reclaimed) via an automated retention policy.

Release notes: RELEASE.md · Full history: docs/CHANGELOG.md

Expected artifacts for 9.9.2 release must use exact filenames:

• dist/ltcai-9.9.2-py3-none-any.whl
• dist/ltcai-9.9.2.tar.gz
• ltcai-9.9.2.tgz
• dist/ltcai-9.9.2.vsix
• src-tauri/target/release/bundle/dmg/Lattice AI_9.9.2_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 9.9.2.
• 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.
