The Tenant AI Chat Solution Accelerator leverages Neon Serverless Postgres on Azure to provide organizations with a framework for deploying tenant-specific, AI-powered chat applications that prioritize data privacy and security by isolating each user's data in separate databases. This solution enables users to engage in secure conversations with internal documents or APIs without relying on public AI services like ChatGPT, supporting features such as customizable personas, voice interactions, and API extensions. Utilizing various Azure services, including Azure OpenAI, Azure Key Vault, Azure Blob Storage, Azure App Service, and Azure Speech Service, the accelerator allows for enterprise-ready deployment with flexible authentication options and a customizable chat experience. Developed with tools like Node.js, Next.js, and Tailwind CSS, the solution offers an accessible entry point for organizations to create private chat environments, with deployment options available through Azure Developer CLI or Azure Portal, and cost management strategies to optimize resource usage.
