The Exa & Deepseek Chat App is an open-source chat application designed to perform real-time web searches through Exa's API, combined with the Deepseek R1 language model for inference, to offer a more accurate chatting experience. Built with Next.js, TailwindCSS, and TypeScript, and hosted on Vercel, it allows users to access the latest web information during chats and engage in intelligent conversations powered by a robust language model. This application is freely available as open-source, suitable for both developers and business users, and can serve as a foundation for developing chat tools.
