Quora’s mission is to grow the world’s collective intelligence. We do this by connecting people and AI to share knowledge, collaborate, and solve problems together. By reducing friction in how intelligence is shared—publicly on Quora and privately on Poe—we’re building platforms that make knowledge more accessible and accelerate learning and progress for everyone. Quora is a global knowledge sharing platform with hundreds of millions of monthly unique visitors, connecting writers who have knowledge across millions of topics with a global audience of readers who want to learn from their collective experience. Poe aggregates access to the best models from many different AI companies in a single chat interface across all platforms, and enables creators to build and monetize applications that use these models.
