Let AI Help You "Digest" Professional Books and Easily Build a Knowledge System

In today's information explosion era, acquiring knowledge has become increasingly convenient, but we also face the challenge of information overload. For students learning professional knowledge and researchers, efficiently grasping a comprehensive theoretical book has always been a headache. Imagine having a powerful assistant that can quickly clarify the structure of a professional book, extract key points, notes, and courseware, and even generate exam questions. Now, AI can be that assistant.

When we tried to use AI to process a 400-page English linear algebra book, we found that tools like DeepSeek and Kimi were not up to the task, and the RAG method was not perfect. However, don't worry, there's a "hero" that has mastered the skills to tackle such challenges - Gemini, which we'll call "G Teacher" for now.

Gemini 2.0 Pro has a strong "appetite" and can handle the large linear algebra book. After uploading the book, it extracted all the key concepts, including definitions, explanations, important examples, and relationships between concepts. We also asked it to divide the key points into blocks using [chunk] and [/chunk] markers. After a few minutes of "chewing," the task was completed. We then imported the extracted key points into Obsidian, where we could further process and visualize the relationships between concepts.

Gemini can also generate beautiful courseware based on the extracted key points. Using the plugin, we can even generate exam questions and creative inspiration. This kind of AI-powered service is extremely helpful for teachers and students. With Gemini, we can have AI "digest" books and provide us with easily absorbable knowledge. If you're interested in trying this out, don't hesitate to take action and dust off those forgotten books.
