What Is Perplexity AI?
Perplexity AI is an AI-powered search engine that answers your questions directly — instead of showing you a list of links like Google. It searches the web in real time, reads the relevant pages, and gives you a clear, sourced answer with references you can click to verify.
Launched in 2022, Perplexity has grown rapidly and now serves millions of users who are frustrated with Google's increasingly cluttered search results. It's particularly popular with researchers, students, journalists and professionals who need accurate information quickly.
We decided to test it seriously — using it as our primary research tool for a full month instead of Google. Here's what we found.
Quick summary: Perplexity AI is the best AI search tool available in 2026. The free plan is genuinely useful. Pro is worth it if you do serious research daily — but casual users will be fine on the free tier.
Pricing & Plans
Perplexity offers two plans:
| Feature | Free | Pro (€20/month) |

| Image generation | ✗ No | ✓ Yes |
| Perplexity Pages | ✗ No | ✓ Yes |

Note: The free plan is genuinely useful for most users. We recommend trying it free for 2 weeks before upgrading to Pro.
Our 30-Day Test Results
1. Research & Fact-Finding
This is where Perplexity absolutely shines. We used it to research topics for our AI tool reviews — finding statistics, checking facts and understanding complex topics quickly. Instead of opening 10 browser tabs, we asked Perplexity one question and got a comprehensive answer with sources in seconds.
The source citations are the killer feature. Every claim comes with a numbered reference you can click to verify. This makes Perplexity far more trustworthy than ChatGPT for research, which sometimes presents information confidently without sources.
2. Current Events & News
Because Perplexity searches the web in real time, it always has up-to-date information. We asked about recent AI tool launches, pricing changes and company news — it answered accurately every time. This is a massive advantage over ChatGPT Plus, which has a knowledge cutoff date.
3. Technical Questions
We tested it with technical questions about our server setup, Nginx configuration and Linux commands. It performed well — often finding the exact solution from the right documentation page. Not as conversational as ChatGPT for back-and-forth problem solving, but excellent for finding specific answers.
4. Creative Tasks
Perplexity is not built for creative writing and it shows. When we asked it to write blog post introductions or brainstorm ideas, the results were dry and generic. For creative work, ChatGPT Plus is significantly better.
5. Replacing Google
For about 70% of our Google searches, Perplexity gave a better, faster answer. The remaining 30% — mostly local searches, shopping, image searches and very niche topics — still needed Google. We ended up using both tools rather than replacing one with the other.
Score Breakdown
Perplexity AI vs Google — Which Should You Use?
Head-to-Head Comparison
| Task | Perplexity AI | Winner | |
|---|---|---|---|
| Research questions | Direct sourced answer | List of links | Perplexity |
| Current news | Real-time with sources | News results | Tie |
| Local searches | Limited | Maps, reviews, hours | |
| Shopping | Product info only | Prices, stores, deals | |
| Fact checking | Cited sources | Requires clicking links | Perplexity |
| Technical docs | Summarised answer | Links to official docs | Perplexity |
| Images | Limited (Pro only) | Full image search |
Our verdict: Use Perplexity for research and knowledge questions. Keep Google for local searches, shopping and images. They complement each other perfectly.
Is Perplexity AI Pro Worth €20/Month?
For researchers, journalists, students and professionals who spend significant time finding and verifying information — yes, absolutely. The Pro plan pays for itself in time saved within the first week.
For casual users who occasionally look things up — the free plan is more than enough. You get unlimited basic searches and 5 Pro searches per day, which covers most everyday use cases.
One important consideration: at €20/month, Perplexity Pro is the same price as ChatGPT Plus. If you have to choose between them, ChatGPT Plus is more versatile for writing and creative tasks. But if you primarily need fast, accurate, sourced research — Perplexity wins.
Our recommendation: Start with the free plan. If you find yourself hitting the 5 daily Pro search limit regularly, upgrade to Pro. If the free plan covers your needs — it's a brilliant free tool and you don't need to pay.
