NotesLM Edge extension security report

NotesLM is a comprehensive browser extension designed to enhance your experience with Google NotebookLM and ChatGPT by streamlining the way you copy, manage, organize, and export your notes and chat conversations. Tailored for students, researchers, content creators, and productivity enthusiasts, NotesLM addresses one of the most common challenges—extracting and preserving valuable AI-generated insights—by seamlessly integrating into your workflow and safeguarding every thought you gather. With NotesLM, the tedious process of manually selecting and copying notes becomes a thing of the past. The extension injects convenient, native-style "Copy Note" buttons directly into the NotebookLM and ChatGPT interfaces. A single click copies the entire note, including its title, full content, and rich formatting elements such as bold text, headers, lists, tables, and even mathematical notation rendered via KaTeX. Once copied, your note is preserved instantly in a local, encrypted history vault—an offline, private repository that ensures none of your research or ideas are lost, even if you accidentally close your browser tab. The local history dashboard is equipped with powerful search and filtering tools that let you quickly locate notes by title or keywords. You can efficiently organize your library, delete outdated entries, or switch to a distraction-free “Reader Mode” for focused review. NotesLM’s advanced deduplication prevents duplicated saves by intelligently merging identical or related notes, maintaining a clean and well-structured archive. Accidentally deleted notes are safely stored in a trash/recycle bin, from which they can be easily restored or permanently erased. Beyond simple note capture, NotesLM supports robust export capabilities tailored for academic and professional use. Transform any saved note or chat conversation into beautifully formatted PDF documents or editable Word (.doc) files with a single click. This feature preserves the original formatting, including mathematical formulas and metadata like authorship and source information, making it ideal for creating polished reports, papers, or presentations directly from your collected insights. Designed with speed and efficiency in mind, the extension employs lightweight algorithms and robust selectors to quickly detect and extract content without slowing your browser. It supports multi-site functionality, allowing copying from NotebookLM, ChatGPT, and a universal mode that works across any website. For users seeking cross-device convenience, optional Google login enables secure, encrypted synchronization and cloud backup via Firebase, making your notes accessible anywhere while adhering rigorously to privacy standards. Privacy is a cornerstone of NotesLM. By default, all your data is stored locally on your device, ensuring no browsing history or unrelated personal information is collected or transmitted. Cloud sync is strictly opt-in and encrypted, and the extension requires only minimal permissions limited to accessing notebooklm.google.com to enable its saving features. This approach guarantees your intellectual property remains private and secure, providing peace of mind as you manage sensitive or valuable research. Overall, NotesLM is an essential companion for anyone leveraging Google NotebookLM or ChatGPT to capture knowledge, boost productivity, and organize insights with ease. Whether you are drafting essays, conducting research, or curating personal knowledgebases, NotesLM simplifies the process by delivering smart copying, reliable history management, advanced exports, and privacy-first design—all packed into an intuitive, fast, and lightweight browser extension.
