Condense Course Material into Comprehensive Notes with Gemini NotebookLM

What you’ll get

You will transform lengthy course materials (like an 80-page PDF) into concise, structured, and comprehensive study notes, typically around 20 pages. This method leverages AI to quickly extract key information, definitions, and examples, saving you significant time compared to manual note-taking.

Tools you need

• Gemini NotebookLM (freemium): An AI-powered notebook that helps you summarize, ask questions, and generate content from your uploaded documents.
• iLovePDF (freemium): A web tool to easily split large PDF files into smaller, manageable chapters or sections.

Steps

1. Split your course material: The author stresses the importance of splitting large documents. Use a PDF splitter to break your course material into smaller, chapter-sized PDF files. This helps the AI process information more effectively. Go to https://www.ilovepdf.com/split_pdf. Upload your large PDF file. Choose to split by range or extract all pages into separate files, then download the smaller PDFs. You should have several smaller PDF files, each representing a chapter or a manageable section of your original course material.

2. Upload one chapter to NotebookLM: Open Gemini NotebookLM and create a new notebook. Upload one of your newly split chapter PDF files. Visit https://notebooklm.google/. If you don’t have an account, sign in with your Google account. Click ‘Create new notebook’. Then, click ‘Upload documents’ and select one of your smaller PDF chapter files. Wait for it to process. The PDF content will appear in your notebook, ready for the AI to work with.

3. Generate comprehensive notes: Use the provided prompt to instruct NotebookLM to create detailed and organized notes from the uploaded chapter. In NotebookLM, open the chat interface for your notebook. Copy and paste the following prompt:

   Please create a comprehensive, clear, and organized set of notes based on the provided resource. Ensure that all key terms, concepts, nuances, and practical examples are included. The notes should cover definitions, detailed explanations, principles, and related examples. The notes should be structured logically with headings and subheadings to enhance readability. Include detailed explanations of key terms, principles, and examples to illustrate complex ideas. Aim for clarity, precision, and depth to help in understanding the material thoroughly.

   NotebookLM will generate a set of structured notes, condensing the chapter’s content into a more digestible format. The author states this prompt condenses ~80 pages into ~20 pages of clear, structured notes.

4. Repeat for other chapters: Continue this process for each remaining chapter of your course material. For each subsequent chapter, upload it to your NotebookLM notebook (or a new one if you prefer to keep them separate) and apply the same note-generation prompt. You will accumulate a full set of comprehensive notes, chapter by chapter, covering your entire course material.

Notes & variations

Many online PDF splitters offer free tiers similar to iLovePDF. For AI note-taking, other freemium chat AI tools like ChatGPT (chatgpt.com) or Claude (claude.ai) could be used, but they might require more careful prompt engineering and lack NotebookLM’s integrated document management. A common mistake is uploading the entire large document without splitting it first. As the author notes, AI models struggle with very large chunks of data, leading to lower quality or incomplete notes. Always split your documents into manageable sections. Experiment with the prompt. While the provided prompt is excellent, you might refine it to include specific instructions relevant to your course (e.g., ‘Focus on practical applications for engineering students’ or ‘Summarize for a beginner audience’). The author also mentions a Chrome extension called Norra that automates this workflow. While specific steps aren’t provided in the excerpt, it could be a useful tool to explore for further efficiency if you frequently perform this task.
