Credit: Shimul Sood / Android AuthorityI personally love NotebookLM, though it’s far from the only tool I’ve used for summarizing information or extracting research data. It is arguably the very best, though, as pretty much every alternative is closer to a supplement than a true replacement. That said, there is one that gets very close.Open Notebook is virtually a clone of NotebookLLM’s core functionality, including stand-out features like audio summaries, the ability to ask questions about your research sources, and so much more. Of course, nothing is perfect, and it isn’t without catches. Below, I’ll dive into what I love about Open Notebook, what is less ideal about it, and how to give it a try for yourself.
