Perplexity
The search engine that reads the web for you — and delivers answers with cited sources.
By Thiago Lourenço Martins
A search engine that answers instead of just listing links
Perplexity is an AI-powered search engine. You type a question — the way you would ask a knowledgeable colleague — and receive a direct, natural-language answer with clickable, cited sources right below. Think of it as a Google that, instead of opening ten tabs for you to piece together an answer, delivers the conclusion with references. The key difference from a regular chatbot: the information comes from the live web, not from a frozen memory that may be out of date.
Research that used to take an afternoon now takes minutes
A consultant walks into a prospecting meeting knowing nothing about the client's industry. They open three tabs, read four articles, and try to remember numbers. It is slow, and the sources often contradict each other.
With Perplexity, one specific question — "What are the main challenges in Brazilian pharmaceutical retail in 2026?" — returns an organized overview, with links to verify every claim, in under two minutes. You arrive at the meeting prepared.
5 ways to use Perplexity in practice
Consultant, manager, or salesperson: before meeting a new client, ask Perplexity for a summary of the industry, competitors, and recent news about the company. You arrive with sharp questions, not generic ones.
Need to choose between two tools, systems, or service providers? Ask directly for the differences, pros, and cons. The answer comes organized with sources — no need to open dozens of tabs.
Has a tax, health, or labor regulation changed that affects your client? Perplexity searches official sources and trade publications and summarizes what changed — with links so you can confirm.
Need a concrete number — industry growth rate, satisfaction index, market size — to back a slide? Ask and receive the figure with a cited source, ready to include in your presentation.
Paste the link to a long article or public document and ask for the main points. Works with consulting reports, technical news, and research institute publications.

Tips & common mistakes
Do this
- Ask specific, contextualized questions: include the sector, country, and time period to get the most relevant data.
- Use Spaces for projects you will revisit often — the history helps Perplexity understand the accumulated context.
- Always click the sources before using data in a report. The citation makes it easy, but verification is your responsibility.
Real limitations
- The free plan has around 5 Pro Searches per day. For heavy use, you will hit the limit quickly.
- It may cite outdated sources without clearly flagging the date. Always check the publication year before using the data.
- It cannot access content behind a paywall or login. Paid sources (consulting reports, closed academic journals) are out of reach.
