+1 Google’s NotebookLM is amazing. In addition to the functionality you mention, I tried loading the PDF for my entire Practical AI Programming with Clojure book and had it generate an 8 minute podcast that was very nuanced - to be honest, it seriously blew my mind how well it works. Here is a link to the audio file it automatically generated https://markwatson.com/audio/AIClojureBook.wav

NotebookLM is currently free to use and was so good I almost immediately started paying Google $20 a month to get access to their pro version of Gemini.

I still think the Groq APIs for open weight models are the best value for the money, but the way OpenAI, Google, Anthropic, etc. are productizing LLMs is very impressive.
