Google’s NotebookLM, an experimental AI-powered notebook, is now available on iOS, iPadOS, and Android platforms. It offers similar insights to ChatGPT and Google Gemini chatbot services but is limited to accessing specific documents and sources. It provides summaries and important data points, reducing the risk of hallucinations. NotebookLM offers services like document questions, summarization, idea generation, and podcast-style overviews. It can also help users revise courses or take notes on documents. The tool is available for iOS, iPadOS, and Android.
