Both Multilo and NotebookLM use different approaches for citation verification. NotebookLM describes “this paper says that '…',“ while Multilo takes you to the original paper from your library and highlights the exact section for you. It goes deeper in verification, and it happens inside your Multilo workspace, where the original paper is shown side by side to your draft.
Furthermore, Multilo’s claim check agent is specific, which checks every citation against real sources and identifies the relevancy, while NotebookLM doesn’t offer that.
