Setting Up WhatsApp AI Pro: From Download to First Reply
The desktop app installs in 5 minutes if nothing goes wrong, 10 if you hit one of three gotchas. QR scan, agent setup, knowledge base, draft mode — in that order.
Alright, let's get this running
The whole setup takes about 5 minutes if nothing goes wrong, maybe 10 if you hit one of the gotchas I'll mention below. It's a desktop app — not a browser extension, not a SaaS dashboard. You download it, install it, and it runs on your machine.
If you prefer to watch rather than read, here's the full walkthrough:
Download and install
Grab the installer from the Download page.
- macOS: Works on both Intel and Apple Silicon (M1/M2/M3/M4). Needs macOS 12 Monterey or later.
- Windows: Windows 10 or later, 64-bit.
On Mac, you might get a "this app is from an unidentified developer" warning the first time. Right-click the app, click Open, and confirm. Standard macOS thing.
Connect your WhatsApp
Open the app, click Add Session in the sidebar, and scan the QR code with your phone's WhatsApp app (Settings > Linked Devices > Link a Device).
Important gotcha: If you already have WhatsApp Web open in a browser, close it first. WhatsApp allows multiple linked devices, but having both open simultaneously can cause sync weirdness — messages showing up in one place but not the other. Just close the browser tab before scanning. You can always reopen it later.
You can connect multiple WhatsApp accounts if you need to. Each one gets its own isolated session in the sidebar.
Set up translation (2 minutes)
Go to Settings > Translation, pick the language you read and write in, and toggle on Auto-translate incoming messages. Done.
From now on, incoming messages get translated to your language in real-time. When you reply, your message goes out in the customer's language. They'll have no idea you don't speak Portuguese or Arabic or whatever they're writing in.
Configure your AI agent (this is the important part)
Settings > AI Agent. Three modes to choose from:
- Suggest draft — AI writes a reply, you review and send. Start here. Seriously. Even if you're confident in the AI, start here for the first week so you can see what it's doing.
- Auto-reply — AI sends replies automatically. Great for FAQs and routine stuff once you trust the responses.
- Manual observe — AI watches conversations and builds profiles but doesn't draft anything. Useful if you just want the CRM/profiling features.
Next, upload your product info. This is what separates a generic chatbot from something actually useful. Upload your product catalog, price lists, FAQ documents, company policies — whatever your sales team needs to reference when answering questions. The AI uses this as its knowledge base, so when a customer asks "what's the price for 500 units of product X?", it quotes your price, not a hallucinated number.
Set the tone (formal, casual, somewhere in between) and you're live.
The CRM builds itself
You don't need to set up the CRM separately. It populates automatically from your conversations. Every contact gets a profile with:
- Conversation summaries
- Products they've asked about
- Tags and labels you can customize
- A lead tier (A through D) based on buying signals
Check the contact panel on the right side of any conversation to see it.
Things that trip people up
"The AI keeps saying things I didn't tell it." Your knowledge base probably has gaps. If the AI doesn't have your product info, it'll try to be helpful with general knowledge — which means it might guess wrong on pricing or specs. Upload more documents. The more specific your knowledge base, the more accurate the responses.
"Responses are too formal / too casual." Adjust the tone setting in the AI agent config. You can also add specific instructions like "always include product links" or "never promise delivery dates without checking."
"I want auto-reply for simple questions but manual review for quotes." You can set this up with escalation rules. Simple FAQ queries go auto, anything involving pricing or custom orders gets flagged for your review. Check Settings > AI Agent > Escalation Rules.
Start with suggest-draft mode, spend a week watching what the AI does, tweak your knowledge base and tone settings, then gradually move toward auto-reply for the routine stuff. That's the whole playbook. Download here if you haven't already.
