I use Perplexity every day. That's not a sponsored statement — I don't pay them anything, no money, no subscription. But I discovered it about a year ago and have since replaced Google with it for certain types of queries.
Why am I telling you this? Because there's a concrete difference from ChatGPT that beginners often don't see clearly.
The key difference from ChatGPT
ChatGPT (and Claude, Gemini, etc.) are based on a model trained up to a specific date — the so-called "knowledge cutoff." Anything that happened after that, the model doesn't know. It can guess, but it doesn't know.
Perplexity, on the other hand, searches the internet live with every request. It's an AI search engine, not an AI chatbot. That distinction matters:
- Current events? Perplexity can answer.
- Today's opening hours? Perplexity looks it up.
- Who won the game yesterday? Perplexity knows.
ChatGPT would either guess or tell you: "That's outside my knowledge."
And the sources — that's the thing
Perplexity always shows where the information comes from. Every statement is linked to a source. That matters, because you can then check whether it's actually true.
That sounds obvious. But it isn't. When you ask ChatGPT for facts, you get an answer with no citation. You just have to trust it's correct. Or verify it yourself. With Perplexity, the source is right there next to the answer.
My personal experience: the citations are usually solid — Wikipedia, official sites, news outlets. Occasionally a less reputable source shows up. But at least I can see immediately where the information is coming from.
What's free
The free version of Perplexity is surprisingly usable. You get:
- Unlimited standard searches (using GPT-3.5-class models)
- Source citations with every answer
- "Focus" modes: Web, Academic, YouTube, Reddit, and more
- A clean interface without annoying ads
What you don't get without a subscription:
- Unlimited "Pro" searches (uses stronger models like GPT-4o or Claude)
- Image generation
- File uploads
For straightforward research, the free version is more than enough.
When Perplexity beats Google
Here's what I've figured out for my own usage:
Perplexity works well for:
- Current news with context ("What's going on with X right now?")
- Research summaries ("Explain quantum computing to me, with sources")
- Comparisons ("What are the differences between provider A and B?")
- Questions that need information from multiple sources
Google is better for:
- Specific local searches ("pizza delivery near my street")
- Image search
- When you want to go directly to a specific website
- Shopping and price comparisons
ChatGPT/Claude is better for:
- Creative writing
- Editing or summarising long text
- Complex multi-step tasks
- When you want a dialogue, not just a single answer
A concrete everyday example
Recently I wanted to know what AI regulations the EU was currently debating. On Google: a pile of links, lots of ads, I have to filter everything myself. On ChatGPT: a solid summary — but a year out of date. On Perplexity: a current summary with links to EU documents and news articles from the past few weeks.
For that kind of thing, Perplexity has become my first tool.
Bottom line: worth trying
Available for free at perplexity.ai — no account needed to start (only if you want to save your searches). Just ask a question and see how the answer compares to Google.
My recommendation: use Perplexity for anything current and fact-based. Use ChatGPT or Claude for anything creative and conversation-based. Google stays for local searches and navigating directly to specific websites.
Three tools for three different jobs. That's more efficient than one tool for everything.
Unpaid recommendation from personal experience. I use Perplexity for free and have no connection to the company.
