FridayOS-Lite
技术小白也能拥有的 AI 第二大脑：无需翻墙、无需订阅，跟着图文 ~20 分钟装好 Obsidian + Claudian + cc-switch + DeepSeek V4。
FridayOS-Lite is an AI agent skill that transforms Obsidian into an intelligent second brain powered by Claude and DeepSeek V4. It introduces Vibe Knowledge Management (VKM), enabling users to manage their knowledge base through natural language instead of manual folder creation, tagging, or linking. The skill uses a six-region partition system (Inbox, Workbench, Knowledge, Skills, Archive, Core) that the AI builds automatically from a single blueprint file. Designed for non-technical users, it requires no VPN, works with affordable Chinese LLM providers, and integrates Obsidian, Claudian, Claude Code, cc-switch, and DeepSeek V4 into a token-efficient workflow.

FridayOS-Lite — FAQ
What is FridayOS-Lite and what does it do?+
FridayOS-Lite is an AI agent skill that turns Obsidian into an intelligent knowledge management system called Friday. It lets you capture, organize, and retrieve notes using natural language commands instead of manual folder structures, powered by Claude and DeepSeek V4.
How do I install FridayOS-Lite?+
First install Node.js and Obsidian, then set up Claude Code via npm, configure cc-switch to connect to DeepSeek V4, and install the Claudian plugin in Obsidian. Finally, download FRIDAY-BLUEPRINT.md and tell the AI to build your brain from it. Complete step-by-step instructions are provided in INSTALL.md.
Which AI clients work with FridayOS-Lite?+
FridayOS-Lite works through the Claudian plugin in Obsidian, which connects to Claude Code. The system uses cc-switch to route requests to DeepSeek V4 or other compatible LLM providers.
Do I need API keys or a VPN to use FridayOS-Lite?+
You need a DeepSeek V4 API key from platform.deepseek.com, which does not require a VPN and costs pennies per query. No foreign subscriptions or VPN services are required.
Is FridayOS-Lite free to use?+
The software itself is free and MIT-licensed. You only pay for DeepSeek V4 API usage, which is extremely affordable—building a brain costs ¥0.10 and complex queries cost around ¥0.02 each. A heavy user ran the system for a week for under ¥20.
What's the difference between FridayOS-Lite and the full FridayOS?+
Lite focuses on teaching knowledge management with the six-region partition system and manual planning. The full FridayOS adds automated capture from messaging apps, mechanical safeguards, health checks, and lets the AI run the entire brain autonomously under a contract.
