Why CEVIZ?

Cloud-only AI tools send every keystroke off-device and bill you monthly forever. Local-only tools are slow on complex tasks. CEVIZ does both: fast local inference for routine work, cloud escalation for hard problems — with your explicit approval before anything leaves your machine.

Key Features

🔀 Hybrid AI Routing
Scores each prompt on a 0–100 complexity scale (length, code blocks, domain keywords, paragraph count). Scores under 45 go local; 45–69 show an escalation banner; 70+ recommend cloud. You stay in control.

🔒 Privacy-First Architecture
Session data, project context, and vault notes never leave your machine. Cloud API keys are stored in VS Code SecretStorage. No telemetry, no analytics, no external logging.

📚 Obsidian Vault Integration
Indexes your vault with ripgrep (5-minute TTL cache, up to 5,000 notes). Relevant notes are injected into prompt context automatically. AI responses include [[wiki-link]] badges that open the source note with one click.

🧬 RAG Self-Development System (market-unique)
Ingests your whitepapers and RSS articles into a ChromaDB vector store. Proposes updates to its own system prompt based on absorbed knowledge. Every change requires your explicit approval — with diff preview and one-click rollback.

💬 Session & Project Management
Per-workspace session isolation with inline rename, pin, star, and sort. Generates CONTEXT.md per project directory and auto-detects completion keywords to keep project state current across sessions.

🌐 Multi-OS · 6 Languages
One-command backend installers for Linux (systemd), macOS (launchd), and Windows (WSL2 / native). UI localized in Korean, English, Turkish, Arabic, Persian, and Russian.

Quick Start

1 — Install the Extension

From the Marketplace:
Search CEVIZ in the VS Code Extensions panel, or:

code --install-extension ceviz-ai.ceviz

From a release .vsix:

# download ceviz-0.2.1.vsix from https://github.com/eonyakoh-tech/ceviz/releases
code --install-extension ceviz-0.2.1.vsix

2 — Install the Backend

The CEVIZ backend runs an Ollama inference engine alongside a FastAPI proxy. Download the installer from Releases.

Linux (Ubuntu / Debian)

chmod 700 install-linux.sh && bash install-linux.sh
# Preview without applying: bash install-linux.sh --dry-run
# English output:            bash install-linux.sh --lang=en

macOS (Intel / Apple Silicon)

chmod 700 install-macos.sh && bash install-macos.sh

Windows (WSL2 recommended)

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
.\install-windows.ps1
# Force native install (no WSL2): .\install-windows.ps1 -ForceNative

All installers are idempotent. Run the dependency checker first if you want to verify prerequisites:

bash check-dependencies.sh      # Linux / macOS
.\check-dependencies.ps1        # Windows

3 — Configure & Chat

1. Click the CEVIZ brain icon in the Activity Bar to open the sidebar panel.
2. Click ⚙️ Setup Wizard → pull gemma3:4b + nomic-embed-text (RAG required).
3. Set ceviz.serverIp in VS Code Settings if your backend is on a remote host (default: localhost:8000).
4. Type your first prompt. The routing indicator shows 🟢 Local / 🟡 Hybrid / 🔴 Cloud.

Tip: Press Ctrl+Alt+C in the editor to attach selected code to the next chat message.

FAQ

Does CEVIZ send my code to the cloud?
Only if you explicitly choose Cloud mode or confirm an escalation prompt. In Local mode, all processing happens on your machine. The extension contains no telemetry.

Which local models are recommended?
The Setup Wizard recommends the best fit for your hardware. A reasonable starting point: gemma3:4b for general chat, qwen2.5-coder:1.5b (PN40-class hardware) or qwen2.5-coder:3b (16 GB RAM) for code tasks. nomic-embed-text is required for RAG.

Can I use my own API key?
Yes — all plans are BYOK. Keys are stored in VS Code's SecretStorage, encrypted at rest, and never transmitted to CEVIZ servers.

What happens if the backend goes offline?
CEVIZ caches up to 20 recent responses and serves keyword-matched answers from cache. An offline banner appears in the UI and clears automatically when the connection is restored.

Is my Obsidian vault modified?
Read-only. CEVIZ never modifies existing notes. It can create new notes in 00_Inbox/ when you explicitly save a chat response via the save dialog.
