About

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”.

About

SurfSense is an AI-powered research and knowledge management assistant that lets you connect and query all your personal and team data in one place using natural language, acting as a highly customizable open source alternative to tools like NotebookLM and Perplexity. It lets you link internal knowledge sources such as Notion, GitHub, Slack, Gmail, Google Drive, YouTube, and other apps, then build a unified searchable knowledge base where you can ask questions and get cited answers in real time while choosing from over 100 leading LLMs or even local models for privacy and control. It supports real-time collaboration with team presence, roles, and permissions, and centralized workflows to find, ask, and act on information quickly, turning scattered files, messages, and documents into a coherent workspace with powerful hybrid search across connected sources and advanced retrieval techniques.
