Stacks vs NotebookLM
NotebookLM is Google’s tool for studying a set of sources you add to a notebook, with grounded answers and audio overviews. Stacks keeps everything you save as you browse and puts it inside ChatGPT and Claude. NotebookLM is better for deep study of a chosen set; Stacks is better for using all your saved research in the AI tools you already work in.
