About Help Scout AI Answers

Help Scout AI Answers Landing Page Screenshot

Help Scout AI Answers is customer support helpdesk with widget-only ai chatbot. Help Scout AI Answers is a customer self-service chatbot embedded in Help Scout's Beacon widget, powered by OpenAI. Critical limitation: RAG capability is NOT exposed via API—it only functions within the embedded Beacon widget. This makes it fundamentally different from RAG-as-a-Service platforms, as developers cannot query AI programmatically for custom chat interfaces, mobile apps, or backend integrations. Founded in 2011, headquartered in Boston, MA, the platform has established itself as a reliable solution in the RAG space.
