NotebookLM—Google’s AI-driven research and note-taking platform—has quickly become a standout in the productivity arena. By letting you import PDFs, slide decks, and other notes, it enables you to query the material in plain language. Powered by Google’s Gemini model, it generates summaries, extracts key takeaways, and spots patterns so you can absorb critical information in a flash.
As capable as NotebookLM is, it isn’t the only option. You might need broader file-type support, built-in audio recording, features fine-tuned to your workflow, or a different pricing structure. Whatever the motivation, looking at alternative tools can help you land on the ideal solution for your research and note-taking style.
Below, I’ll highlight six standout substitutes—ranging from AI-enhanced assistants to classic note apps with a modern upgrade—that can boost your productivity and streamline how you manage information.
Nouswise
Nouswise is by far the closest AI tool that can replace Notebooklm fully, it has all capabilities of podcast, query from documents with citations, writing assistant and so on.
