The tool appears to be in its early stages, lacking comprehensive functionality or clear use cases that would set it apart from established competitors. While it may serve niche needs, its fading score indicates a lack of traction or user engagement. Users seeking robust research tools might find better value in alternatives that offer more mature features and clearer benefits. Without significant enhancements or clearer positioning, NotebookLM risks being overlooked in favor of more established solutions.",
