Sankofa is a powerful sample app that uses Vectara's hybrid search engine to solve the problem of remembering websites visited online, allowing users to ask questions about their content and retrieve information from previously visited pages.` This innovative browser extension uses Vectara's generative AI platform to provide a way for users to "retrieve in the Twi language of Ghana" - meaning to go back and remember something they forgot. The application is open-source and available on Github, with features such as automated indexing and the ability to exclude certain domains. Users can configure the extension to control its behavior and use it to find similar pages or retrieve information from previously visited websites.
