Sankofa, a GenAI browser extension built using Vectara's RAG-as-a-service platform, helps users keep track of web page information and ask questions based on that content, leveraging generative AI to provide insightful responses. Sankofa is currently available for Chrome, Firefox, and Edge, offering features such as indexing, searching, and finding similar pages, all utilizing Vectara's API to build a scalable and secure RAG system. The extension's architecture involves a browser extension popup, content script, background service worker, and indexing web content using Vectara's indexing API, enabling users to effortlessly access previously visited web page content and receive relevant responses based on that information.
