NotebookLM is a powerful AI tool from Google that can automatically generate beautiful presentations. However, many users face a common problem: generated slides can only be exported as PDF or images, making direct text editing impossible. When you spot a typo or layout issue, you often have to ask the AI to regenerate, which may cause format issues or quality degradation.
This article introduces 5 practical solutions to help you easily edit NotebookLM-generated presentations.
Why Are NotebookLM Slides Hard to Edit?
NotebookLM presentations have a unique characteristic: text, background, and illustrations are all merged into a single layer. This means each slide is essentially an image, and you cannot select and modify text like in PowerPoint.
