Knock Knock App
Hey Product Hunt 👋
I'm Anna, co-founder of Knock Knock.
8 months ago we launched here with a simple belief.
AI engagement qualifies. A live video call closes.
You showed up. You used it. You loved it. And then you asked for more. Make it remember. Make it pick up the phone. Make it follow up. Make it run my whole sales motion, not just the moment at the door.
So we built more.
Today we're launching NOX.
The doorbell now has a brain.
NOX is the central memory that turns Knock Knock into a complete AI sales layer. Website. Phones. Inbound. Outbound. All running on one brain.
One AI sales brain. Website. Phones. CRM. All of it.
🧠 Knows every visitor in real time
📂 Reads your CRM live (GHL, HubSpot, and more)
💬 Picks up the chat with full memory
📞 Takes the call. Makes the call.
📅 Books the meeting
⚡ One-tap human takeover (the buyer never sees the seam)
☕ 5am morning brief in plain English
The wow moment. NOX is on a call. You're listening live. Tap once and you're on the line. NOX fades out. Your face fades in. Same call. No transfer. Nobody else in this category ships this.
AI qualifies. Humans close. That's been our belief from day one. NOX makes it work across every channel.
Why we built it. I'm a non-technical founder running marketing, growth, and sales mostly alone. I couldn't afford a six-person sales team. I couldn't operate a six-tool stack. So we went back to our own product and built the brain we needed.
NOX is what came out of that.
Built for: → Solution agencies and vertical agencies who want to white-label and resell → Founders running lean → Sales teams tired of stitching six tools together
Founder pricing is open today. 100 seats. Half price for the first month. White-label setup free. Omar and I are personally onboarding the first wave.
Tell me what you think. Ask anything. Drop DEMO in the comments and I'll get you in.

This feels like a big step beyond a normal website chatbot. how do you decide when a visitor is ready for a live conversation versus just needing more automated nurturing?
