Doctrine is an AI tool designed for web apps that allows users to seamlessly integrate generative AI capabilities into their applications. Users can harness their stored knowledge to answer user inquiries or incorporate AI features into their apps. The tool offers a robust API for quick integration, supporting knowledge ingestion from diverse sources like databases, websites, documents, images, and more. It automatically converts various file types into text, vectors text into high-dimensional spaces, and facilitates web content ingestion through sitemaps or individual pages. Doctrine provides a Chat UI for direct embedding or allows users to create their own UI using the API.
