Though most know Google’s AI-powered research a**istant, NotebookLM, for its viral features like Audio Overviews and Mind Maps, these features weren’t part of the original launch when the tool first debuted under Google Labs. In case you don’t know what Google Labs is, it’s essentially Google’s experimental playground where the tech giant rolls out early versions of its AI tools to gather feedback and refine them before releasing them more widely. What’s interesting is that not all of Google Labs’ experimental projects make it past the testing phase. Some get shelved completely.
