Certainly is built on a conversational AI engine that supports natural language understanding (NLU) and intent classification across multiple languages. The platform provides a no-code bot builder with a visual flow editor, alongside APIs and webhooks that allow developers to integrate custom business logic, external data sources, and third-party services. It supports omnichannel deployment — spanning web chat, email, SMS, and messaging apps — and offers a robust handoff protocol to live agents via integrated helpdesk platforms. Developers can leverage Certainly's REST APIs to manage bot configurations, retrieve conversation analytics, and trigger automated workflows programmatically.
