Kortex AI is an AI-powered knowledge management workspace and browser companion designed to function as a “second brain”. It allows researchers, writers, and power users to capture web sources, structure notes, store reusable prompts, and integrate directly with AI research platforms like Google’s NotebookLM and conversational models (such as ChatGPT, Claude, and Gemini).

Key Usages & Workflows

Web Research & Source Capture: Highlight snippets from articles, forums (e.g., Reddit), or social posts and instantly save them with preserved links and citations.
NotebookLM / Gemini Enhancement: Connect directly to NotebookLM to import whole chat threads, group references into folders, organize prompts, and bypass standard UI limits.
Multi-Model LLM Workspaces: Access and switch between multiple models (like Claude, ChatGPT, and Gemini) within a single document or chat workspace for drafting, summarizing, or analyzing files.
Audio & Podcast Generation: Convert curated research notebooks into custom audio overviews or private podcast RSS feeds (compatible with Spotify or Apple Podcasts) to listen to research on the go.
Content & Prompt Management: Store reusable prompt libraries, tag/organize notes with nested folders, and export research bundles into clean Markdown, PDF, or ZIP files.

Limitation

Third-Party API Dependency: Features relying on integrations or extensions (such as NotebookLM, Claude, or ChatGPT) are vulnerable to UI changes or reverse-engineered API updates from external platforms.
Tiered & Usage-Based Caps: Premium AI model requests, audio-generation minutes (for podcast feeds), and bulk imports are subject to tiered monthly limits or credit quotas depending on your plan.
Browser & Platform Constraints: Primarily built as a Chromium browser extension (Google Chrome, Edge, Brave), limiting native mobile workflows or non-Chromium environments.
Quality & Hallucination Risks: Inherits standard LLM limitations—output quality depends directly on the accuracy and context of the ingested source material.

Step 1: Download & Install the Extension

Open a Supported Browser: Launch Google Chrome, Microsoft Edge, Brave, or any Chromium-based browser.

Visit the Store/Site: Go to kortex-notebooklm.com and click “Install Extension” (or search for Kortex on the Chrome Web Store).

Add to Browser: Click Add to Chrome $\rightarrow$ Confirm by clicking Add extension.

Pin the Extension: Click the puzzle piece icon 🧩 in your top-right browser toolbar and click the Pin icon next to Kortex for easy access.

Step 2: Sign In / Log In

Dashboard Access: Once signed in, you will see your account status, remaining daily limits (or Pro status), and quick links.

Step 3: Connect & Setup with Google NotebookLM

Open Google NotebookLM: Navigate to notebooklm.google.com in the same browser.
Grant Permissions (First Time): Kortex automatically detects when NotebookLM is open and overlays its enhanced options (such as Export buttons, Prompt Holder, and Source Management) right onto your NotebookLM panel.
