Research without rabbit holes

NotebookLM
“The single most useful AI product Google has shipped. Hand it a folder of PDFs, get back a notebook that actually understands them. The audio overview gimmick is the part everyone shares but the source-grounded Q&A is why it stays open.”

Consensus
“Built for the specific job of synthesising research around a claim, and it does it cleanly. The consensus meter wants to feel like a verdict — treat it as a starting point instead. The citation density is the right kind of overwhelming.”
