What is Perplexity?

Perplexity is a tool created to help streamline the research process. When given a prompt perplexity will use AI Technology to search the internet for real time information to analyze and summarize into a concise natural language text. By doing this, Perplexity helps users find relevant scholarly articles, generate insights, and navigate complex research topics with ease. 

Its core features include a powerful search engine that retrieves academic literature and a context-aware citation tool that clarifies the impact and relevance of sources. Perplexity also provides a list of sources it has used to create its response 

Additionally, Perplexity AI offers a summarization feature that distills large volumes of information into concise, comprehensible summaries, making it easier to grasp key concepts and findings. Ideal for both initial explorations and in-depth research. 

Perplexity Deep Research

In February 2025, Perplexity added a new search mode: Deep Research.  It is based on a similar chain-of-thought based agent as other tools offered by Google's Gemini, OpenAI's Deep Research, and DeepSeek Deep Research.  For researchers, it differs from these products in two important ways:

  • First, one can access it with a free-tier account (with a limited number of searches per day).
  • Second, one can use Perplexity's "Focus" feature to prioritize academic sources (taken from Semantic Scholar and PubMed, primarily).

Searches take about five minutes, and go through a long chain of intermediate searches before an LLM integrates the results into one three-page report.  The report usually draws on text from fewer than a dozen sources, but the final output will return all the websites and documents Perplexity Deep Research discovered along the way, which can sometimes be the most relevant to the user's needs.

The report will be broken down into numerous sections and subsections, and clicking on the title of such sections and subsections will start a new Deep Research search on that particular topic.  One can also ask follow-up questions, and otherwise use it like a chatbot.

Like most such tools, one should expect the report to prioritize the "consensus" rather than innovative, possibly untested new research that might overturn the consensus.  These reports are probably most useful at the outset of researching a particular topic, and discovering seed papers to read and discover subsequent work from.

What is NotebookLM?

NotebookLM is a tool from Google, using its Gemini engine, that allows users to create "notebooks" of text files, PDFs, websites, notes, and more, and "chat" with them to draw insight from all these sources at once. 

It uses a principle called Resource Augmented Generation, or RAG, which basically means that, instead of the chatbot trying to draw on its training data for its response to your query, it sticks as closely as possible to the source material you provide it. This dramatically cuts down on "hallucinations," but if the sources you give it are unclear, contradictory, or contrary to reality NotebookLM's replies may be as well!

On the free tier, a user can upload up to fifty sources per notebook, each of which can have up to 500,000 words (or 200 MB in size).  One can upload PDFs, text files, web pages, Google Docs and Sheets, YouTube videos (from which it extracts the transcript), and more. NotebookLM will extract the text and work from that; it will not update itself automatically if a website or Google Doc changes.

Files you put in a notebook stay within your Google account and are not made public or added to training data; however, as always one should avoid putting sensitive information on the internet if one can.  You can share a notebook with other Google account holders, but they cannot be made truly public.

One feature of NotebookLM that has received a lot of attention is its Deep Dive Conversation feature, where one can create an audio file that simulates two hosts discussing a topic based on your sources.  One can even have a live conversation with the "hosts."

AI Literature Search, Synthesis and Visualization Tools

  • Consensus: this literature search, synthesis and extraction tool draws on citations and open access papers from semantic scholar. It discovers papers, summarizes and extracts data. Consensus also includes a "consensus meter" which will answer a yes/no research question with the percentage of found studies saying yes, no or possibly and integrates with Microsoft CoPilot.  A basic free account provides unlimited searches and some CoPilot integration, or you can upgrade to a paid account.
  • Elicit: this literature search, synthesis and extraction tool draws on citations and open access papers from semantic scholar, with a focus on “empirical research (e.g. randomized controlled trials in social sciences or biomedicine)" to discover papers, as well as summarize and extract data. A basic free account gives you unlimited search, unlimited summaries of 4 papers at once, and other features or you can upgrade to a paid account.
  • ResearchRabbit: dubbed “Spotify for papers,” this free tool draws on citations and open access papers from semantic scholar to create visualizations of connections between papers and scholars, as well as recommend and summarize papers.
