CMD Chatbot 🤖

A zero-install AI chatbot that runs directly in Windows CMD. No Python. No Node.js. No setup. Just configure and chat.

---

Architecture

CMD → Cloudflare Worker → Groq API → Response printed in CMD

---

Why this is different

Most AI chatbots require installing Python, Node.js, or some other runtime. This one uses only what Windows already has built in — curl and CMD. Nothing is installed, nothing is left behind on the host PC.

---

Features

• ✅ Zero installs — works on any Windows 10/11 PC out of the box
• ✅ No traces — nothing saved on the host PC after you exit
• ✅ API key never exposed — hidden inside Cloudflare Worker
• ✅ Protected — secret token blocks unauthorized access to your Worker
• ✅ Portable — run from a USB or a single memorized command
• ✅ Free — Cloudflare free tier (100k requests/day) + Groq free tier

Setup

Step 1 — Get a free Groq API key

1. Go to console.groq.com
2. Sign up and go to API Keys
3. Click Create API Key and copy it

Step 2 — Deploy the Cloudflare Worker

1. Go to cloudflare.com and sign up free
2. Dashboard → Workers & Pages → Create Worker
3. Name it anything (e.g. chatbot)
4. Click Deploy then Edit Code
5. Delete the default code and paste the contents of worker.js
6. Click Deploy
7. Go to Settings → Variables and Secrets → add these two:

Variable Name	Value
GROQ_API_KEY	Your Groq API key
ACCESS_TOKEN	A secret word you choose (e.g. superman24)

8. Click Deploy again

Step 3 — Configure bro.bat

Open chatbot.bat and update these two lines:

set TOKEN=your_secret_token_here        ← replace with your ACCESS_TOKEN
set WORKER_URL=https://your-worker-name.your-subdomain.workers.dev  ← your Worker URL

Step 4 — Run it

Double click chatbot.bat or run in CMD:

chatbot.bat

How it works

You type a message in CMD
        ↓
bro.bat sends it to your Cloudflare Worker via curl
        ↓
Worker verifies your secret token
        ↓
Worker calls Groq AI API with your message
        ↓
Groq returns a response
        ↓
Worker sends back plain text
        ↓
curl prints it directly in CMD

---

Security

• Your Groq API key is never in the bat file — it lives inside Cloudflare's encrypted environment variables
• The ACCESS_TOKEN blocks anyone who finds your Worker URL from using your API credits
• The bat file clears the screen on exit leaving no chat history on the host PC
