Go to perplexity.ai

Perplexity works in any browser with no download required. You can run a search immediately without an account — but signing up is worth it. A free account saves your search history, lets you organise research into Collections, and unlocks personalised follow-up threads.

Find the mode selector before you search

Below the search bar you will see mode options: Web, Academic, and Deep Research. Each one changes where Perplexity looks for information. Choosing the right mode before you type your query is the single most important habit to develop.

Ask a full question — not a keyword

Perplexity is not a keyword search engine. It is a research assistant. The more specific and complete your question is, the better the answer will be. Think about what you are actually trying to find out, then phrase it as a sentence.

Web

Use this mode when

→You are starting on a topic and want a broad overview before narrowing down

→You need information about something recent — news, product releases, events

→The topic is not academic — practical guides, how-to questions, opinions

Note: Web mode casts the widest net. Good for exploration, but always check what it is citing — blog posts and opinion sites are included.

Academic

Use this mode when

→You are writing a research paper or essay that needs academic citations

→You want Perplexity to prioritise journal articles and scholarly sources

→You are checking whether a claim is supported by peer-reviewed research

Note: Academic mode is not exhaustive — it searches across publicly available scholarly content, but it may miss papers behind paywalls. Use Google Scholar after Perplexity to go deeper.

Deep Research

Use this mode when

→You are writing a dissertation or a research paper with a broad scope

→Your topic has multiple competing perspectives you need to cover

→You want a structured, exportable report rather than a single answer

Note: Deep Research takes 2–5 minutes because it runs many searches and synthesises the results. The output is significantly more comprehensive than a standard search. You can export it as a PDF.

Set your mode to Academic before typing

For assignment research, start in Academic mode by default. You can always switch to Web if you need broader coverage, but Academic gives you higher-quality starting sources.

Write your question as a full sentence

Do not keyword-stuff. Write what you actually want to know. Include the specific angle, the time period, and any key constraints your assignment requires.

Read the answer — then click every citation you plan to use

Perplexity shows numbered citations alongside its answer. Do not just read the summary. Click through to every source you intend to use in your assignment. Verify the source says what Perplexity claims before you cite it.

Ask follow-up questions in the same thread

Perplexity maintains context throughout a conversation thread. After your first answer, ask follow-up questions in the same chat rather than starting a new search. This lets Perplexity narrow its answers based on what you have already found.

Save useful sources immediately

As you find sources worth keeping, copy the URL or add the search thread to a Perplexity Collection. Do not rely on your browser history — good sources are easy to lose in the middle of a research session.

Locate the numbered citations in the answer

Every factual claim in a Perplexity answer has a superscript number linked to a source. The full list of sources appears in a panel alongside or below the answer. Each number corresponds to one source.

Click through to every source you plan to cite

Never use a source you have not clicked on. Perplexity's summaries are accurate most of the time — but not always. The only way to know whether a source actually supports a claim is to open it and read the relevant section yourself.

Check three things about every source

Before adding a source to your bibliography, verify: Is it a reputable publisher or journal? Is it recent enough for your assignment requirements? Does it actually say what Perplexity claimed it says? If any answer is no — skip that source.

Format the citation immediately using ZoteroBib or QuillBot

Once you have verified a source is usable, paste its URL into ZoteroBib or QuillBot's citation generator and format it into your required style (APA, MLA, Chicago). Do this now rather than at the end — you will save hours.

Perplexity (Academic mode)

Run 3–5 broad searches on your topic to map the landscape. Identify key debates, major researchers, and the main arguments on each side.

Google Scholar

Search for the specific papers Perplexity surfaced. Download or save the most-cited and most-relevant ones. Citation count is a useful quality signal.

Elicit

Upload or search for your papers in Elicit. Use it to extract key findings, methodology, and conclusions from multiple papers at once in a comparison table.

Perplexity (follow-up threads)

Use Perplexity to explore specific sub-questions that your paper reading raised. Each sub-question is a new Academic search or a follow-up in an existing thread.

ZoteroBib

Paste every source URL into ZoteroBib as you confirm it. Build your complete bibliography in your required citation style throughout the process — not at the end.

Claude

With your research notes, key findings, and outline ready — write the literature review in Claude. Feed it your structure, key sources, and the arguments you want to make. Edit the output into your own voice.

Workaround

Use Perplexity to identify the key authors and debates, then run those names through Google Scholar or your university database for comprehensive coverage.

Workaround

Use Academic mode for research assignments. Always click the citation and verify the publisher before including a source in your bibliography.

Workaround

Never use a source without clicking it and reading the relevant section yourself. The citation is the starting point for verification, not the end of it.

Workaround

Batch your research sessions. Plan your search questions before opening Perplexity so you use each AI search count efficiently rather than running exploratory searches.

Workaround

Use Perplexity to identify which papers are worth your time. Then read the ones your assignment actually depends on.
