Description

Kortex is a browser extension that transforms Google’s NotebookLM into a cohesive and interactive repository of knowledge, enabling users to capture and organize essential insights that might otherwise be lost in chat histories and various tabs. With just one click, it allows for the archiving of complete AI conversations from platforms like ChatGPT, Gemini, Claude, and Perplexity, while also enabling the saving of any highlighted text from webpages as accurately cited references directly to NotebookLM. Furthermore, Kortex simplifies the process of exporting sources, chats, or curated notes in formats such as Markdown, JSON, or as a downloadable .zip file, and it seamlessly integrates with Google Docs, allowing for easy document transfers to NotebookLM. To enhance notebook management, Kortex provides the functionality to delete multiple notebooks simultaneously from the dashboard. Created with the goal of ensuring users can easily access their saved information and never overlook an idea again, Kortex can be installed within seconds and currently supports a growing community of users developing their own "second brain" for enhanced productivity and creativity. This innovative tool not only streamlines the organization of thoughts but also encourages users to harness their creativity in a more structured manner.
