Kortex
Kortex is a Chrome extension that adds export, import, automation, and organization capabilities directly inside Google's NotebookLM. It addresses the limitations of NotebookLM by turning temporary AI conversations and sources into a permanent, searchable knowledge repository that grows over time.
The tool enables one-click saving of chats, sources, and insights. Users can highlight, annotate, edit, and remix sources. It supports connecting insights across notebooks through global context and referencing of previously saved material. Organization features include nested folders and tags.
Kortex also provides bulk operations such as delete and Google Docs sync. It allows saving of prompts to avoid re-typing. The extension works with AI conversations, web research, and social media content to create a unified repository.
It is delivered as a browser extension for Chrome and is free to install with no credit card required. The service has recorded over 200,000 exports and 105,000 imports while being used by more than 80,000 people.
