Quarterzip

Quarterzip builds AI screenshare agents that deliver real-time, in-product user assistance. Its agent sees a user's screen, guides them by voice, and executes the steps alongside them in real time, powering onboarding, activation, and customer support at scale without additional headcount. Teams embed Quarterzip through a hosted Link URL or a client-side JavaScript SDK that launches a draggable in-app call (window.Quarterzip.open/close), and receive signed call.completed webhooks (Standard Webhooks HMAC) carrying transcripts and call ratings for CRM and analytics integration. Customers include Bloomreach, Apollo, Dovetail, Airspeed, and Zuper. Quarterzip is ISO 27001 certified.

Quarterzip is profiled on the APIs.io network. Tagged areas include Company, AI Agents, Customer Support, Onboarding, and User Activation.

The Quarterzip catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Quarterzip’s developer surface includes documentation, API reference, getting-started guide, signup flow, changelog, authentication, and 14 more developer resources.
