Overview
Discourse
Discourse reimagines the traditional internet forum as a modern, mobile-friendly conversation space. You can move away from cluttered comment sections and static boards to an interface that feels like a continuous conversation. It uses infinite scrolling instead of pagination, allowing you to catch up on discussions naturally without clicking through dozens of pages.
You can use it to build a public support community, a private internal knowledge base for your team, or a fan hub for your brand. The platform includes built-in trust levels that automatically grant active members more permissions as they contribute, helping your community moderate itself. Whether you host it yourself for free or use their managed hosting, you get a tool that scales from small hobby groups to massive enterprise communities.
Sierra
Sierra is a conversational AI platform that helps you transform customer service from simple chat into autonomous problem-solving. Instead of basic bots that just answer questions, you can build AI agents that actually perform tasks—like upgrading a subscription, tracking a complex shipping route, or managing a return—by connecting directly to your existing enterprise systems and data.
You can ensure your AI agent stays on brand and follows your specific business logic through a robust reasoning engine. The platform focuses on high-quality, human-like interactions that reduce the need for manual intervention while improving customer satisfaction. It is designed for consumer-facing brands that need to scale their support operations without sacrificing the nuance and personality of their brand identity.
