FridayOS-Lite is a setup guide for building a personal knowledge management system called Friday using Obsidian (a local notes app), Claude Code (an AI coding and chat tool), and DeepSeek V4 (a low-cost AI model that works without a VPN). The goal is to let someone with no technical background set up an AI that lives inside their notes app, organizes their information, and answers questions about it. Setup involves installing five free or inexpensive tools: Node.js, Obsidian, Claude Code, a routing adapter called cc-switch, and a community plugin for Obsidian called Claudian. Once installed, you drop a single blueprint file into a folder, type one sentence telling the AI to build from it, and the AI creates a structured set of folders that form the knowledge base. No command-line configuration is required beyond a copy-paste step. The knowledge base is organized into six named regions: an inbox for fast capture, a workbench for active projects and daily plans, a knowledge library for permanent notes, a skills folder for reusable routines, an archive for source material, and a core folder that holds the rules the AI follows. All files are plain text stored locally, not locked into any cloud service. The system is designed to keep AI costs very low. The folder structure routes queries to only the relevant region, uses summary overview files to avoid loading many documents at once, and stores reusable procedures once rather than re-explaining them each time. The README reports that a 169-note vault cost roughly 0.10 yuan to build and around 0.02 yuan per complex query. A demo vault is included so you can see how the system works before setting up your own. The Lite version does not include automated integrations or advanced monitoring features, those are part of the full FridayOS project.
