Your startup's AI Customer Support teammate
KnockKnock lives on your site as a simple chat widget and connects directly to Slack. When a customer writes in, KnockKnock answers. It knows your product, learns over time, and asks for help only when needed. You stay in control, but most issues never reach you.
KnockKnock is an AI teammate that handles your customer conversations—sales, support, and retention—so you don't have to.
Built for founders
Most tools are designed for support teams. We built KnockKnock for the people who don't want one.
Works out of the box
No setup calls, no complex configuration. Just add one line of code and you're ready to go.
Support on autopilot
KnockKnock learns your product and handles most customer conversations without any intervention.
Updates you in Slack
Get notified where you already work. No new tools to learn or dashboards to check.
How it works
Add one line of code
Drop the KnockKnock snippet into your site. No setup calls - just copy and paste.
Pick a channel
Pick where you want updates to go. Most people use Slack. We'll route customer messages and only bother you when needed.
Let the AI handle the rest
KnockKnock replies to customers, answers questions, flags churn risks, and loops you in if things get weird.
Run customer ops with one person. Forever.
KnockKnock is designed for founders who want to focus on building, not managing support teams.
