# 🤖 FridayOS‑Lite

### One document, one sentence, one AI second brain

**No tech skills. No template to download.** Install the Obsidian + Claudian five-tool stack,
drop one Brain Blueprint file into a folder, say one sentence —
and the AI builds your second brain, **Friday**, by itself.

## What Lite is — and isn't

**Lite focuses on one thing: teaching you to manage a knowledge base with Obsidian + Claudian** — the body of Friday's second brain. Learn the six-region partition idea, and let the AI capture, organize, and retrieve for you. Daily and weekly plans you write by hand in Obsidian, or dictate to Friday in chat.

It does **not** do automated integrations: no Feishu bot, no capture-from-anywhere messaging, and no mechanical safeguards (lint health checks, memory decay, inbound security). Those belong to the full [FridayOS](https://github.com/Neusoft-Intelligent-Laboratory/FridayOS) — where the AI doesn't just take notes for you, it **runs the whole brain under a contract**. Once the partition idea clicks, your folder moves over as-is. Zero migration.

**Lite is for people who:**
- Have never heard of Claude or Obsidian and don't know where to download them
- Freeze at words like "command line" or "environment variable"
- Don't want a VPN or a foreign-currency subscription
- Just want an AI that remembers, organizes, and answers

> If you can click a mouse and copy-paste one line, you can install it. ✅

## In three lines

1. **A folder is your brain** — all notes as local plain text, never locked in.
2. **An AI lives in your notes app** — chat with Friday in Obsidian's sidebar; it captures, organizes, and retrieves.
3. **You don't build the brain** — download [`FRIDAY-BLUEPRINT.md`](./FRIDAY-BLUEPRINT.md), tell Friday "build from this", and the six regions appear by themselves.

## 💡 This way of working has a name: Vibe Knowledge Management

You've heard of vibe coding — say what you want, the AI writes the code. **Vibe Knowledge Management (VKM)** is the same move applied to knowledge: **drive your knowledge base with natural language, and let the AI do the managing.** You never create folders, tag notes, or fix links by hand. You just talk — capture a stray thought, ask a question, say "the usual" — and filing, linking, and retrieval are Friday's job.

VKM is the core of Friday, and Lite is its smallest complete form. Fair notice: this is a new way of working — how well it replicates beyond us, and how quickly newcomers internalize it, still needs more users to verify. **That's exactly what this repo is for.**

## 🗺️ How it fits together

![FridayOS-Lite — five tools, one signal chain](https://raw.githubusercontent.com/Neusoft-Intelligent-Laboratory/FridayOS-Lite/main/docs/images/tools-flow.gif)

> Indigo = what you touch; teal = what thinks beneath. See [`TOOLS.md`](./TOOLS.md) for what each tool is and why.

## 🚀 Get started (three steps)

| Order | Read | Do |
|---|---|---|
| 1️⃣ Understand | [`TOOLS.md`](./TOOLS.md) | 3 min — what the five tools are for |
| 2️⃣ Install | [`INSTALL.md`](./INSTALL.md) | Set up the stack, then one sentence builds the brain |
| 3️⃣ If stuck | [`FAQ.md`](./FAQ.md) | Troubleshooting + download links |

> 👉 **Beginners: go 1→2→3, don't skip.** Understand first, then install.

## 🧠 Your brain after setup

Six regions, fully explained in [`FRIDAY-BLUEPRINT.md`](./FRIDAY-BLUEPRINT.md):

| Region | Folder | In a line |
|---|---|---|
| 📥 Inbox | `inbox/` | Capture fast, sort later |
| 🎯 Workbench | `exec/` | 3–7 things in motion + weekly/daily plans |
| 📚 Knowledge | `wiki/` | Worth keeping, wikilinked |
| ⚙️ Skills | `skills/` | Repeated work as routines (advanced) |
| 📦 Archive | `raw/` | Source material, read-only |
| 🫀 Core | `system/` | The brain's contract (`CLAUDE.md`) |

## 🎮 Just installed and feeling lost? Play the demo brain

An empty brain is hard to appreciate. We ship a **ready-to-play sandbox** — a fictional 100-person IT company with full employee files, projects, customers, all wikilinked across the six regions, plus 11 demo prompts in three acts that each show something a free chatbot window cannot do. To play: download [`示例大脑-云栈科技.zip`](./示例大脑-云栈科技.zip) (click the ⬇ download button), unzip, open as a vault, follow the demo manual inside. *(Demo content is Chinese-only.)*

## 💸 Token-frugal by design

The six regions aren't just tidy — **they're what makes Friday absurdly cheap to run**. Aggregate queries scan structured frontmatter (dozens of tokens per file) instead of whole documents; every domain has an overview map (MOC) so Friday starts from one page, not eleven; questions open only the region they belong to; and routines live in `skills/` once, invoked by name instead of re-explained every time.

Measured on DeepSeek V4 over a 169-note vault: brain build **¥0.10**, a complex multi-file analysis **≈¥0.02 per question**, 11 of them back-to-back **¥0.26 total**. A real 10-person team ran this architecture for a full week — the heaviest user spent under **¥20**.

## 📦 Tools you'll install (all free / very cheap)

| Tool | Role | From |
|---|---|---|
| Node.js | Foundation | [nodejs.org](https://nodejs.org) |
| Obsidian | The brain's body (notes app) | [obsidian.md](https://obsidian.md) |
| Claude Code | Friday's engine (the AI) | npm (China mirror) |
| cc-switch | Wires the engine to a cheap chip | [ccswitch.io](https://ccswitch.io) |
| DeepSeek V4 | Cheap, no-VPN model | [platform.deepseek.com](https://platform.deepseek.com) |
| Claudian | Brings the AI into Obsidian | Obsidian community plugin |
