Multi-channel AI sales agent
Knock Knock uses a single AI agent, Nox, to handle website chat, inbound calls, outbound calls, and video conversations from one workflow.
Knock Knock
Knock Knock is an AI sales agent for websites that chats, calls, books meetings, and logs interactions to a CRM to capture and qualify leads.
End-to-end AI sales agent for website conversion
Knock Knock is an AI sales layer for websites built around an agent named Nox. It is positioned as a replacement for a stack of separate tools such as chat, voice, scheduling, visitor tracking, and CRM connectors by combining those tasks in one workflow.
The product is designed to engage visitors across onsite chat, inbound phone, and outbound follow-up, then qualify leads, book meetings, and log interactions back to a CRM. The site describes a simple setup flow: add a snippet, connect your CRM, and configure the offer, with a claimed setup time of about 10 minutes.
Core features
Visitor intelligence and live navigation
The product identifies visitors in real time, tracks what they view, and uses that context to decide when to engage.
Lead qualification and booking
Nox can chat, call, book meetings, and push interaction history into a CRM so follow-up information is retained outside the widget.
Human handoff and takeover
The site and pricing pages describe one-click takeover, letting a human step into chat, voice, or video with the conversation context preserved.
Reporting and support workflows
The product sends a plain-English morning brief and supports daily office hours support plus onboarding options on higher plans.
White-label agency tools
The pricing page includes white-label access, an agency portal, and reseller-oriented packaging for agencies managing multiple clients.
Common use cases
24/7 website lead capture
Use Nox to greet site visitors, identify high-intent prospects, answer questions, and book meetings without requiring a rep to be present at all hours.
Inbound call handling
Use the inbound voice workflow to answer calls, capture details, and route qualified callers to a calendar or a human when needed.
Outbound lead follow-up
Use the outbound workflow to follow up with new leads before they cool off, run campaigns, and move warm leads into booked meetings.
Human-assisted sales conversations
Use the one-click takeover flow when a conversation becomes high value or needs a human, while retaining the visitor context and conversation history.
Agency resale and client delivery
Use the agency and white-label packaging to run the product for clients under your own brand and manage multiple accounts from an agency portal.
