Meet Perplexity — what it is and who makes it
Perplexity is Perplexity AI's answer engine that searches first and answers second. It is at its best at a question whose answer is somewhere on the web and needs a citation. It is at its weakest at anything where the sources disagree and somebody has to decide — it will summarise the disagreement rather than resolve it — and knowing both halves is what separates somebody who uses it well from somebody who trusts it blindly.
The concept
Perplexity is a answer engine that searches first and answers second made by Perplexity AI. The models behind it are a choice of frontier models behind a search-first interface, plus its own research modes. None of that matters on its own — what matters is that you know what kind of worker you have hired. At a question whose answer is somewhere on the web and needs a citation is the job you hand it. At anything where the sources disagree and somebody has to decide — it will summarise the disagreement rather than resolve it is the job you keep.
Most people come to a course like this expecting a list of magic words. There is no such list. What there is, is a tool that produces a short answer with numbered citations, which is a different product from a chat, and produces it at a speed no human matches — which means the skill is not in writing the prompt, it is in knowing what a good answer looks like so you can tell the difference.
Here is the first thing to try, worded the way you will word things for the rest of the course:
Read the answer twice. The first read is for the content; the second is for the shape — did it answer the question you asked, or the question it found easiest? That second read is the habit this whole course is built on.
Research the entry-level data analyst market in India right now. Give me the three things employers ask for most, the three things they complain freshers are missing, and the source for each one.Worked example
Two lists with sources behind them — one you can act on this week, and one you can bring to an interview as an observation.
Your practice task
Open Perplexity, ask it the one question you would normally put to a search engine about your own field, and write down two things: whether the answer was right, and whether it would have taken you longer to find it yourself.
Do this before moving on. Reading a solution teaches the shape of it; typing it teaches you.
Key takeaway
Perplexity is a answer engine that searches first and answers second made by Perplexity AI.
