Why Build This?
Most AI tools today are cloud-dependent, censored, or expensive. Schools in China face additional hurdles: Docker Hub is blocked, model downloads crawl at 2 MB/s, and "safe" cloud filters neuter educational content.
We built a machine that doesn't care about any of that. Once set up, it runs entirely offline. Students can ask LLMs anything. Teachers can share files without WeChat compression destroying PDFs. Everything is local, private, and fast.
What We Built
🧠 AI Chat
Ollama serving 5 local LLMs via Open WebUI. Students chat with Qwen3, Llama 3.1, and more — no internet required.
📁 File Sharing
Nextcloud for documents, photos, and collaboration. No WeChat file size limits. No compression.
🎬 Media Server
Jellyfin streams educational videos to any device on the LAN. Subtitles, transcoding, beautiful UI.
🛡️ DNS Filter
AdGuard Home blocks ads and trackers at the network level. Protects all connected devices.
📚 Offline Wikipedia
Kiwix serves Wikipedia, Wiktionary, and other ZIM files without internet. Entire encyclopedia on disk.
💾 Backup Strategy
Restic for data + Timeshift for system snapshots. Two-tier backup on a 4TB SSD.

China-Specific Notes
Building this in China requires workarounds for network restrictions. We documented every one:
- Docker Hub blocked → Use
ghcr.ioand China mirrors (USTC, Tencent, 163, Daocloud) - Model downloads slow → Set 2-hour timeouts; Ollama resumes partial downloads automatically
- Port 53 conflict →
systemd-resolvedowns port 53; map AdGuard web UI to 3001 instead - International font servers blocked →
ttf-mscorefonts-installerfails; non-critical, ignore or purge
ghcr.io or China mirrors.

What's Next
- Complete Kiwix ZIM library setup (Wikipedia + educational content)
- Pinokio + ComfyUI for image generation (pending GPU memory assessment)
