The Google AI feature I'm most surprised by is NotebookLM. It can process web pages, articles and more content into one audio discussion delivered by two AI hosts. This feature is so popular that Google is considering offering a paid plan. Most recently, Meta has come up with their alternative but in open source form.
It is named NotebookLLama because it uses the Llama language model. It will process the text file and generate a transcript before the prom system then generate audio with dramatization for the discussion to sound more natural. It's just that for now, it's still in its early stages and the voice sounds very robotic with the AI host also hallucinating a lot. The discussion is also said to sound unrealistic.

For now it is still uncertain what the final NotebookLlama-based product will be. Meta AI is also still planned to be expanded in stages with many features still limited in certain countries. To this day no AI service can offer the same great quality as Google NotebookLM.
