Kortex

What is Kortex?

Kortex is a Chrome extension that acts as an intelligent integration layer between your AI chat platforms and Google NotebookLM. Instead of being just another web clipper, it bridges active conversations from ChatGPT, Claude, Gemini, and Perplexity directly into NotebookLM's structured knowledge base. With one-click archiving, precision text snipping, and bulk export options, Kortex turns scattered insights into a searchable, interconnected second brain.

Who it's for

• Researchers and students who need to save full AI chat histories alongside web sources without manual copy-pasting
• Writers and content creators who want to capture specific text blocks from any webpage with perfect citations for later reference
• Productivity enthusiasts who rely on NotebookLM as their central knowledge hub and need seamless import from multiple AI tools

Key features

One-Click LLM Archiving

A dedicated button appears directly inside ChatGPT, Claude, Gemini, and Perplexity. Click it to save the entire conversation to a new or existing NotebookLM notebook. The imported source is formatted cleanly, with prompts and responses clearly separated.

Highlight & Snipe

Right-click any text on any webpage to save it as a perfectly-cited source in NotebookLM. This precision approach avoids importing entire messy pages and focuses only on the content that matters.

Effortless Exporting

Export your sources, chats, or curated notes as Markdown, JSON, or a single .zip file. This gives you full data freedom to move your knowledge outside NotebookLM whenever needed.

Google Docs Integration

Send Google Docs directly to NotebookLM with a single click from the Docs website itself, eliminating the need to download and re-upload files.

What stands out

"Kortex turns scattered AI conversations into a structured knowledge base you can actually search, export, and build upon."

Most extensions only clip web pages. Kortex goes deeper by embedding itself inside AI chat interfaces, letting you archive entire reasoning chains with one click. The combination of precision snipping, bulk export to Markdown, and Google Docs support makes it a complete pipeline for capturing, organizing, and owning your digital research.

Worth checking out if…

You use NotebookLM regularly and want to stop losing valuable insights from your AI chats. If you've ever scrolled back through endless conversation history or manually copied text from ChatGPT into a document, Kortex eliminates that friction entirely. It's especially useful for anyone who values data portability and wants their knowledge base to remain accessible outside any single platform.
