If you use Perplexity for research and want the answer built only from papers you can filter and cite, this page compares the two fairly. Perplexity is fast and covers the web, news and policy well. AI for Research searches a scholarly index, filters by study type, keeps papers in a Library and moves the answer into a draft.
What Perplexity is best at
Perplexity is an answer engine that shows its sources up front. Its Research mode runs dozens of searches, reads hundreds of sources and finishes most tasks in under 3 minutes, and reports export to PDF, a document or a shareable Page [1]. You can choose an Academic focus to prioritize peer-reviewed journals and scholarly articles [2], and Wiley journal and book content is available to every user through Connectors and sources [3]. Its developer documentation describes an academic filter for builders [4]. For getting oriented in a new topic in ten minutes, especially one that mixes research with news, regulation or market data, Perplexity is one of the quickest tools there is. It also offers Education Pro at $10 a month for verified students [5].
Where AI for Research differs
The difference is the starting point. Perplexity starts from web search ranking and lets you lean it toward scholarly sources. AI for Research starts from scholarly records, with the web as one optional source.
- Sources you pick by type. The Ask box offers All papers, Medical (PubMed, Europe PMC), Preprints (arXiv, bioRxiv, medRxiv), Web and My Library, alone or together.
- Filters on the papers themselves. Year, study type, journal quality tier (from the journal's h-index in OpenAlex), citations, open access and peer-reviewed only. Retracted papers are left out by default.
- Every source is a record you can save. Results show the paper, not a page about it. Click Save cited papers to put them in your Library.
- Citations that point somewhere. Citation markers that point to no real source are dropped. The Cited, All read and Web tabs show what was used and what was read.
- A consensus line. Each cited study is labeled by how it bears on your question, and the line counts them, for example "2 of 4 studies that test the question support it".
- Next steps in the same place. Open in editor with live citations, Claim Check, Citation check, Slides, or a full Systematic Review project.

How to use Perplexity and AI for Research together
- Orient in Perplexity. Ask the broad question. Note key terms, authors and two or three landmark papers.
- Ask the scholarly version here. In the Ask box, paste a focused question, choose a depth (Summary 1 credit, Deep 15), pick sources and set filters.
- Check the landmark papers appear. Open the All read tab. If a paper you expected is missing, search for it in Find Papers and save it.
- Save and expand. Click Save cited papers, then open one in Citation Map to see what it cites and who cites it (0 credits).
- Write. Click Open in editor; the citations stay live and the reference list builds itself.
A worked example
Example (invented, for illustration). An undergraduate asks Perplexity how microplastics affect human health. The answer mixes news articles, an agency fact sheet and two reviews: a good map. She then asks in AI for Research, "What do human studies show about microplastics and inflammation?", choosing All papers and Medical, peer-reviewed only, from 2018. The Summary answer (1 credit) cites six papers; the consensus line shows that 2 of 3 human studies that test the question report an association, and the other cited papers are animal or lab studies, which the labels make plain. She saves the six papers and writes her paragraph in the editor. Total cost: 1 credit.
What AI for Research does not do
- It is not a general web assistant. The Web source exists, but news, shopping or travel questions are not what it is built for.
- It reads abstracts when no open full text exists. Full texts come through Unpaywall.
- No Google Scholar, Scopus or Web of Science search. Search those through your library.
- The consensus line is a count, not a weight of evidence. A small pilot and a large trial each count once.
- Detailed reports need a paid plan, and the free plan allows 2 Deep reports a day.
What it costs
Free: 45 credits a month. Plus: $12 a month or $96 a year for 750 credits. Pro: $29 a month or $228 a year for 1,500 credits. Summary 1 credit, follow-up 1, Deep 15, Detailed 45; search, filters, Citation Map, the Library and exports cost 0. See pricing.
Who it is for
