Gemini

Gemini is where you get the “open” side—creative output plus live web search—and now it can pull in your NotebookLM notebooks as context. The big win is hybrid queries: I can filter web research through my private project specs and keep the whole conversation persistent in my Gemini history.

Pros

+Access to live web search and stronger content creation
+Can attach NotebookLM notebooks directly in chat for context
+Persistent chat threads make research an ongoing project
+Available to free and paid users (paid users get higher limits)

Cons

-Doesn’t replace the standalone NotebookLM features like audio overviews
-Not as focused on deep study/citation-first workflows as NotebookLM’s original app
