Frequently asked questions

What is Knock and how does it work?
Knock is an AI-powered trend tracking tool that monitors thousands of sources 24/7 for topics you care about. When something starts gaining traction, you get alerted with AI-generated summaries so you can act before the trend goes mainstream.
How early can Knock detect trends?
Our AI typically detects emerging trends 7-14 days before they hit mainstream news. The exact timing depends on the topic and how quickly information spreads, but our pattern recognition is designed to catch signals early.
What topics can I track?
You can track virtually any topic: AI and technology, cryptocurrency, specific industries, competitors, niche interests, scientific research, market movements, and more. If it generates online discussion, Knock can track it.
How do credits work?
Credits are used whenever you perform an action: updating a topic costs 1 credit, generating a social post costs 1 credit, daily briefs cost 2 credits, and deep analysis costs 3 credits. You start with 10 free credits and can buy more anytime. Credits never expire.
Is there a monthly subscription?
