What our analysis found
Kortex NotebookLM: Gemini Notebook Toolkit, used by 100,000 people, is rated caution by Extension Auditor. Our code review reported 1 finding (1 high), led by other. Its permissions mean it can inject scripts into pages.
Key findings
- High
Other
The published manifest summary on CWS only includes permissions ["contextMenus", "downloads"] and host_permissions ["*://[domain withheld]"]. However, the actual bundled manifest includes many more permissions (identity, storage, debugger, scripting, activeTab, unlimitedStorage, alarms) and broad host_permissions including "[domain withheld]" and "[domain withheld]", as well as many domain patterns. This discrepancy prevents users from accurately assessing the extension's access before installation and is a transparency violation.
Analyst notes
The extension's actual permissions (debugger, scripting, identity, storage, unlimitedStorage, activeTab, and broad host_permissions including all URLs) significantly exceed the permissions disclosed in the Chrome Web Store listing (only contextMenus and downloads). This mismatch is a transparency risk and may conceal dangerous capabilities from users. While the code appears legitimate and no data exfiltration to third parties was found, the undisclosed debugger and broad host permissions raise suspicion.

Read the publisher’s full description
Your Power Toolkit for Google NotebookLM! Tired of your valuable intellectual work getting lost in different chats or locked inside research sources? Kortex is the browser extension that transforms Google's NotebookLM into a dynamic, interconnected knowledge base. It seamlessly bridges your AI conversations from ChatGPT, Gemini, and Claude, captures insights from any webpage, and adds powerful tools to manage and export your work. Kortex solves the problem of "trapped" intellectual work. Chat-based LLM interactions and web research are often difficult to search and cross-reference. Kortex breaks down these barriers, allowing you to build a unified, long-term, and truly usable knowledge base in NotebookLM. Key Features: 1) One-Click LLM Archiving: An integrated "NotebookLM" button in ChatGPT, Gemini, Claude, and Perplexity captures your full conversation and seamlessly imports it. 2) Highlight & Snipe: Highlight any text on a webpage, right-click, and send it directly to NotebookLM as a new, perfectly-cited source. 3) Google Docs Integration: Directly import your Google Docs as sources to integrate them with your other research materials. 4) Source Downloader: Easily export all the sources from a notebook into a single, convenient zip file in Markdown or plain text. This core functionality allows users to select multiple research sources from within a Google NotebookLM notebook and export them as a single .zip file containing Markdown (.md) or plain text (.txt) files. 5) Bulk Notebook Management: Select multiple notebooks on your dashboard to manage and delete them all at once. 6) Versatile Chat Export: Export your entire Q&A history from within NotebookLM into clean Markdown, plain text, or JSON files. 7) Curated Briefing Notes: Checkbox-select the most important AI responses in a chat to generate a concise, shareable briefing document with just the key insights. 8) Studio Notes Exporter: Select your notes from the studio and export them in your required format. Benefits You'll Experience: 🧠 Build a Unified Knowledge Base: Stop losing valuable AI interactions and web clippings. Integrate all your insights into one comprehensive and interconnected repository in NotebookLM. 🔍 Easily Search and Cross-Reference: Make your LLM conversations and web snippets fully searchable alongside all your other sources, unlocking their true value. 📤 Extract & Share Insights with Ease: Go from research to report in seconds. Effortlessly export full conversations or create curated summaries for colleagues, clients, or your own records. 🔒 Unlock Trapped Intellectual Work: Break free from the limitations of individual platform UIs and build a powerful, long-term resource from all your AI interactions and research.
