A Quick Heads Up Before We Start

If you're not familiar with the terminal (that black screen with commands), this might be a bit of a learning curve for you. But trust me, it's worth it. Once you get through the setup, the whole thing is pretty magical.

For those who have never touched the terminal before: don't worry, I'll explain every command step by step. Just copy-paste them exactly as shown and you should be fine. And if you mess up somewhere, you can always start fresh.

Now let's get into it.

What's OpenClaw?

OpenClaw (previously known as Moltbot/Clawdbot) is basically an AI assistant that sits on your computer and connects to your WhatsApp. You send it a message, it does things on your PC and replies back. Simple as that.

Think about this scenario: You're grabbing chai with friends and suddenly remember that PDF your colleague needs is on your desktop at home. Instead of rushing back, you just text on WhatsApp: "Find the Q4 report on my desktop." Thirty seconds later, you have it. That's the vibe.

The project has 60,000+ GitHub stars and an active community, so support is pretty solid if you run into issues.

Why Do You Need an API Key?

Before we get into the setup, let me explain this part because a lot of people get confused here.

OpenClaw itself is just a bridge between your WhatsApp and your computer. It doesn't have its own AI brain. It needs to connect to an AI model (like Claude or GPT) to understand your messages and figure out what to do.

Think of it like this: OpenClaw is the body, but it needs a brain to function. That brain is the AI model, and you access that brain through an API key.

The API key is basically your access pass to use these AI models. Every time you send a message, OpenClaw sends it to the AI, the AI processes it, and sends back instructions. You pay for this usage based on how many tokens (roughly words) you use.

Which AI Can You Use?

Here's the good part: OpenClaw works with multiple AI providers. You're not locked into one.

1. Anthropic (Claude)

This is the default and honestly works the best for this kind of task. Models like Claude Sonnet or Claude Opus are available.

2. OpenAI (GPT)

Yes, you can use GPT-4, GPT-4.5, or even GPT-5 if you have access. If you're already paying for ChatGPT Plus, you can use the OpenAI Codex option which uses your existing subscription.

3. Google Gemini

Another option if you prefer Google's ecosystem.

4. Local Models (Ollama)

If you don't want to pay for APIs at all, you can run local models on your machine. Free, but needs a decent computer (8GB+ RAM recommended).

5. OpenRouter

This is like a proxy that gives you access to multiple models through one API key. Pretty convenient if you want to switch between models.

The Cost Factor

OpenClaw itself is free and open-source. The cost comes from the AI API usage:

Using Anthropic Claude:

  • Light usage (few commands a day): ₹800-2,500/month

  • Moderate usage (regular file tasks): ₹2,500-6,000/month

  • Heavy usage (constant automation): ₹6,000-12,500/month

Using OpenAI:

  • Similar pricing, depends on which model you use

  • GPT-4 is cheaper than Claude Opus for most tasks

Using Local Models (Ollama):

  • Completely free

  • But your computer needs decent specs (8GB+ RAM recommended)

Setup Guide for Windows

Since most of us in India use Windows, let's start with that. OpenClaw runs on Windows through something called WSL2 (Windows Subsystem for Linux). Don't worry, it's easier than it sounds.

Step 1: Install WSL2

Open PowerShell as Administrator (Right-click on Start → Windows Terminal (Admin) or PowerShell (Admin))

Run this command:

wsl --install

This will install WSL2 with Ubuntu. Your computer might ask you to restart. Do that.

After restart, Ubuntu will open and ask you to create a username and password. Remember these, you'll need them.

Step 2: Enable Systemd (Required for OpenClaw)

Open Ubuntu from your Start menu and run these commands one by one:

sudo tee /etc/wsl.conf >/dev/null <<'EOF'
[boot]
systemd=true
EOF

Now go back to PowerShell (as Admin) and run:

wsl --shutdown

Open Ubuntu again and verify it worked:

systemctl --user status

If you see some output without errors, you're good.

Step 3: Install Node.js

Inside Ubuntu, run these commands:

curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt-get install -y nodejs

Verify installation:

node --version

(Should show v22 or higher)

Step 4: Install OpenClaw

Still inside Ubuntu:

curl -fsSL https://molt.bot/install.sh | bash
exec bash

Step 5: Run the Setup Wizard

openclaw onboard --install-daemon

This opens an interactive wizard. Follow the prompts:

  1. When it asks for AI provider, choose based on what API key you have

  2. When it asks for WhatsApp, select it and scan the QR code with your phone

For different AI providers, you can use these specific commands:

For Anthropic (Claude):

openclaw onboard --auth-choice token

For OpenAI:

openclaw onboard --auth-choice openai-api-key

For OpenAI with ChatGPT subscription:

openclaw onboard --auth-choice openai-codex

For Google Gemini:

openclaw onboard --auth-choice gemini-api-key

Step 6: Connect WhatsApp

When the QR code appears on your screen:

  1. Open WhatsApp on your phone

  2. Go to Settings → Linked Devices

  3. Tap "Link a Device"

  4. Scan the QR code on your screen

Done!

Setup Guide for Mac

Mac setup is actually simpler since it runs natively.

Step 1: Install Homebrew (if you don't have it)

Open Terminal and run:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Step 2: Install Node.js

brew install node

Verify:

node --version

(Should show v22 or higher)

Step 3: Install OpenClaw

curl -fsSL https://molt.bot/install.sh | bash
exec bash

Step 4: Run the Setup Wizard

openclaw onboard --install-daemon

Follow the same prompts as Windows setup.

Step 5: Grant Permissions

This is important for Mac users. Go to: System Settings → Privacy & Security → Full Disk Access

Add your Terminal app (or iTerm if you use that).

Without this, OpenClaw won't be able to access your files when you're away.

Step 6: Connect WhatsApp

Same as Windows:

  1. Open WhatsApp on your phone

  2. Go to Settings → Linked Devices

  3. Tap "Link a Device"

  4. Scan the QR code

Setup Guide for Linux (Ubuntu/Debian)

Step 1: Install Node.js

curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -
sudo apt-get install -y nodejs

Step 2: Install OpenClaw

curl -fsSL https://molt.bot/install.sh | bash
exec bash

Step 3: Run Setup Wizard

openclaw onboard --install-daemon

Step 4: Connect WhatsApp

Same process as above.

Useful Commands After Setup

Once everything is set up, here are some commands you'll use often:

Check if OpenClaw is running:

openclaw gateway status

Restart the service:

openclaw gateway restart

Stop the service:

openclaw gateway stop

Start the service:

openclaw gateway start

View available AI models:

openclaw models list

Switch to a different model:

openclaw models set openai/gpt-4.5-preview

Check for issues:

openclaw doctor

What Can You Actually Do With It?

Here are some real examples of messages you can send:

Find Files Remotely

  • "Find that screenshot I took yesterday in my Downloads folder"

  • "Search for the project proposal PDF on my desktop"

  • "Where is my resume file?"

Get System Info

  • "How much disk space do I have left?"

  • "What's running on my computer right now?"

  • "Show me my CPU and RAM usage"

Run Commands

  • "Create a new folder called 'Project X' on my desktop"

  • "Compress all the images in my Downloads folder"

  • "Delete all .tmp files from my Downloads"

Automate Tasks

  • "Check my calendar for tomorrow"

  • "Search my notes for meeting minutes from last week"

  • "Send me a summary of files modified today"

A Few Things to Keep in Mind

  1. Security: This tool has access to your terminal, so be careful. The docs recommend using a separate WhatsApp number for the assistant instead of your personal one.

  2. Keep your PC running: Obviously, your computer needs to be on and connected to the internet for this to work.

  3. API costs can add up: If you're using it heavily, keep an eye on your API usage. Consider using local models (Ollama) if cost is a concern.

  4. WSL2 for Windows users: Remember, on Windows, OpenClaw runs inside the Linux environment (WSL2), so your files will be accessed through that. The path structure might look different (/mnt/c/Users/YourName/ instead of C:\Users\YourName\).

Troubleshooting

OpenClaw not responding?

openclaw doctor

This will check for common issues and try to fix them.

WhatsApp disconnected?

openclaw gateway restart

Then re-scan the QR code if needed.

Commands not working? Make sure the gateway is running:

openclaw gateway status

Need to start fresh?

openclaw reset

Final Thoughts

I've seen a lot of AI tools lately, but OpenClaw feels different because it's actually solving a real problem. Not everything needs to be a fancy app with a subscription, sometimes you just need to find that one file while you're not at home.

The setup might look intimidating at first (especially if you're new to terminal commands), but once it's running, it's basically magic. Text your computer, get things done.

If you run into issues, the community is pretty active on GitHub. Don't hesitate to open an issue or check existing discussions.

Have you tried any remote PC control tools before? Would love to know what you're using.

So that's it. Happy Coding!
