FAQ
Everything you need to know
Which channels should I start with?+
Depends on where your buyers come from. If most of your inbound is website traffic, start with chat. If most is phone calls, start with inbound voice. If you're prospecting cold, start with outbound. Most customers add the others within 60 days once they trust the first one. You can switch any channel on or off any time — no contract.
What does Nox actually do, in plain English?+
Nox is the brain that runs Knock Knock. It reads the visitor data your script captures, decides if and when to engage based on your rules, picks the right channel, has the conversation, books the meeting, and emails you a morning brief about everything that happened. You don't open a dashboard. You read the brief.
Does it work with my CRM?+
Yes. Native integrations with GoHighLevel, HubSpot, and a few others. Anything else via Zapier or webhooks. Every conversation Nox has gets logged to the right contact record automatically — including transcripts, intent score, and follow-up notes.
Do I have to do video calls with strangers?+
No. Video is off by default. Turn it on if you sell high-ticket products where face-time closes deals — real estate, premium consultancies, B2B above $5K ACV. Most customers leave it off forever. Nox handles every conversation through chat, voice, or phone — you'll never need to be available.
Can I white-label it?+
Yes. Every plan is white-labeled by default, from Launch ($197/mo) upwards — no add-on needed.
If you're an agency reselling to clients, our agency partnerships are fully white-labeled by default — your brand, your domain, your client portal. Learn about partnering →
How do I get help when I need it?+
Daily office hours on Zoom — included in every plan, even Starter. Drop in, ask anything, watch other customers' questions. Business customers also get 1-on-1 onboarding and a dedicated account manager.
How do I get started?+
Book a demo and we'll walk you through setup. You'll be live with at least one channel within 30 minutes. Book a Demo →
