Perplexity Pro Review: The Research Tool Every Buyer Should Use
An AI search engine that answers with sources. For pre-purchase research on anything from thermostats to washing machines, it has replaced half of our Google workflow.
The best AI research tool for buyers: cited, current, fast - and honest enough to show its sources so you can check its work.
What we like
- Every claim is cited to a live web source you can click
- Answers pull current prices, stock, and specs, not stale training data
- Image input: photograph a spec plate and ask questions about it
- Fast enough to use for quick questions, deep enough for comparisons
What we don't
- Creative and long-form writing is weaker than ChatGPT
- Occasionally over-weights a single bad source
- No price tracking or saved research across sessions
The review
We research products for a living, which makes Perplexity both a competitor and a tool we genuinely use. Pro costs $20 a month and answers questions with live web data and citations. After three months of using it as part of our research workflow, here is an honest assessment of where it earns its subscription and where a search engine still wins.
Why citations change everything
A chatbot that answers from training data can confidently tell you the wrong thermostat specs. Perplexity answers from live search and shows you which pages it used. That single design decision makes it usable for product research, because you can verify the claim in two clicks instead of trusting the model's memory.
In our workflow, it has replaced the 'ten tabs' stage of research. Ask 'compare the Nest Learning Thermostat 4th gen against the Ecobee Smart Thermostat Premium for a house with no C-wire' and you get a structured answer with manufacturer pages, installer forums, and reviews cited - the raw material of a good decision, in one response.
Shopping research specifically
This is where Pro earns its $20. Ask it to find the current price and common complaints for a product and it synthesizes across retailer pages, Reddit threads, and review sites, with each claim attributed. It is not a substitute for reading a full review like ours, but it is an excellent first pass and a brutal fact-checker.
Limits are real. It has no memory of your saved research between sessions, and it will occasionally lean on one confident-but-wrong source. Click the citations on anything that matters.
Should you buy it
If you research purchases regularly, $20/month is cheap for the time it saves. Start with the free tier - it is genuinely useful and will tell you within a week whether the Pro limits annoy you.

Frequently asked questions
Is Perplexity Pro better than ChatGPT?
For research with sources, yes. For creative writing and long-form drafting, ChatGPT is stronger. Many people use both.
Does the free tier include search?
Yes, with a limit on Pro searches per day. The free tier is a legitimate product, not a trial.
Can it be wrong?
Yes. It cites sources but does not guarantee they are good ones. Click citations for anything consequential - that is the point of the design.
