What reviewers say
Independent, third-party reviews.
“I love notebook it literally reimagines how business owners have meetings and communicate this app is a must have… This tool is phenomenal for slides, overviews, and presentations! You will get lost in this one this is what I call the Rabbit Hole of Ai tools”
“Idea is great and it has long-term potential. But it has the same lousy issues most AI has. Fabricates information. Gets details wrong. Becomes lazy with it's research, getting comfortable repeatedly referencing a small handful of citations.”
“This is one of my favorite apps. I can upload my docs, even multiple docs and complicated topics, and it helps me sort through. It's not perfect, but it makes my life easier. Especially since it gives me references.”
“The app doesn't have parity with the webpage. Trying to manage sources is a pain… to remove a source you have to enter the delete mode time and again and do it one by one… Good to listen to generated podcasts, but insufficient for work.”
“I made a podcast this morning that I didn't get to finish listening to and when I made my coffee and went to finish listening to it it was gone”
“I was an AI skeptic but this app is too useful. I am using it to summarize all the books I couldn't finish either bc they are esoteric or bc of my ADHD.”
“This is a unique research tool based on Gemini AI LLM, 100% suitable for studying a university career, deep researching difficult topics, mind maps, audio summaries, Q&A generations, among other focused but endless possibilities.”
“I'm taking notes about different papers and pdf documents trough notebookLM. The best experience I've had was the 7-9 minutes large podcast of my pdfs or websites.”
“Extremely dumb, it forgets instructions, disobeys direct prompts… even when providing multiple documents as sources, it keeps giving information from one or two documents repeatedly and won't touch other sources.”
“I consider the NotebookLM web app to be the best educational tool available. You can convert any web pages or documents you select into a very engaging video or podcast that provides an explanation of the subject.”
