Google announced it is rebranding NotebookLM to Gemini Notebook, a change initially cosmetic but with signs of bigger plans, including a new Collections feature that groups related notebooks like a playlist. A recent APK breakdown hints the tool may soon let users add website links as sources directly in the Gemini app. The article lists five desired features for the AI tool. First, multi-notebook merging: there is no official way to merge multiple notebooks directly in the app, though third-party tools or uploading multiple notebook links in Google Gemini for cross-analysis exist; the feature is absent because Gemini Notebook is designed around strict source grounding to prevent AI hallucinations, and mixing independent notebooks increases hallucination odds. Second, the ability to download sources: there is no easy way to download previously uploaded sources, such as PDFs and other documents, with only workarounds available.
