Read the full Perplexity review

Perplexity is the AI you use when you would normally open five browser tabs. It combines large language models with live web search to return a written answer that cites its sources inline — so you can verify claims quickly instead of trusting a black box. Pro Search plans queries into multiple steps for deeper questions, Spaces keep research organized across a topic, and Focus modes narrow searches to academic papers, YouTube or Reddit. It is not a replacement for a general-purpose chatbot, but for time-sensitive research it is the fastest tool in the category.

Read the full NotebookLM review

NotebookLM is Google's AI notebook that turns a folder of PDFs, docs, YouTube transcripts and pasted text into a personal research assistant. Every answer it produces is grounded strictly in the sources you upload, with inline citations pointing back to the exact passage. Its standout feature is Audio Overviews — a two-host podcast summary generated from your material, which has become a study and briefing shortcut for millions of users. NotebookLM is the tool of choice when you cannot afford hallucinations because the AI is only allowed to reason from your material.
