Kontxt

Kontxt is a social AI web layer and platform that enables users to save, organize, and share web content and PDFs. It integrates AI for highlighting, tagging, and summarizing, and provides collaboration tools, a CMS, and social networking features.

Kontxt offers a 'Social AI Web Layer & Platform' that allows users to save, organize, and share content. It explicitly mentions organizing content into folders (similar to lists/sections), sharing content, and having a CMS with permissions which implies granular sharing. The interface appears clean and focused on content. It also has user accounts and profiles. While it doesn't explicitly mention 'URL Saving & Preview' or 'Contextual Side Notes' in the same way as URList, the 'Save and collaborate in an AI platform' and 'Add collaboration tools to any site or PDF' suggest similar functionalities for saving and annotating web content. The AI features are a significant differentiator.
