Kortex
Kortex is a browser extension that turns Google’s NotebookLM into an interconnected, dynamic knowledge base, helping users stop losing ideas by capturing and organizing valuable insights that would otherwise remain trapped in chat histories and scattered tabs. It lets you archive full AI conversations from services like ChatGPT, Gemini, Claude, and Perplexity with one click and save any highlighted text on a webpage as a perfectly cited source directly to NotebookLM. Kortex also offers effortless exporting of sources, chats, or curated notes into Markdown, JSON, or a downloadable .zip file, and integrates with Google Docs so you can send documents to NotebookLM with a single click. For notebook management, Kortex enables bulk deletion of multiple notebooks from the dashboard at once. Designed to help users find anything they’ve saved and never lose an insight again, Kortex installs in seconds and supports thousands of users building their own “second brain”.
