NotebookLM vs Perplexity
NotebookLM
It’s my personal research sanctuary where the AI actually stays focused on the facts and doesn't just make stuff up to look smart.
Perplexity
The only way I search for anything now; it gives me the real sources so I can actually trust what I'm reading.

AIght’s take
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.
Perplexity
When I want a sourced answer fast, this is the call — and the Pro version's deep research mode is genuinely a different product. Still treat the citations as a starting line, not a finish line.
