Perplexity
AI-powered search that shows its sources.
By Shaun · Co-founder
Perplexity is an AI-powered search and research tool that answers questions with cited sources pulled in real time from the web. Its core strength is transparency — every claim links back to a source, which makes it far more useful than a standard chatbot for research, fact-checking, and staying current. The free tier is genuinely capable. Where it differs from ChatGPT or Claude: Perplexity is optimised for retrieval and synthesis, not long-form creation or coding. Think of it as a smarter search engine rather than a general-purpose AI assistant.

Quick Verdict
The fastest way to get cited, current answers on any topic. If research speed and source transparency are core to your work, Perplexity Pro at $20/month pays for itself quickly. Use it alongside Claude or ChatGPT rather than instead of them — it excels at finding and verifying information, while the others handle writing and building.

Our Verdict
Perplexity earns an 8.4 as the best AI tool for research and fact-finding — a category where Claude and ChatGPT are weaker by design. If you regularly need cited, up-to-date answers to specific questions, nothing else matches its speed and transparency. The free tier covers most research use cases without a credit card. Where it doesn't compete: long-form writing, creative work, and coding are not what Perplexity is built for, and the Pro plan is harder to justify as a standalone $20/month subscription when ChatGPT Plus and Claude Pro offer broader capabilities at the same price. The strongest case for Perplexity Pro is as a complement to another AI assistant — not a replacement. For researchers, journalists, and analysts who need sourced answers fast, it's the clearest recommendation in its category.

Frequently Asked Questions
Is Perplexity AI free to use?
Yes. The free plan gives real access to the core product including cited web search. Pro Search queries are capped at around 5 per day on the free tier — enough to evaluate the tool before committing. The Pro plan at $20/month removes those limits and adds model choice and file uploads.
Perplexity vs ChatGPT — which is better for research?
Perplexity for research: every answer cites its sources inline, real-time web access is on by default, and the interface is optimised for information retrieval. ChatGPT is stronger for writing, coding, and image generation. The two tools complement each other well — many professionals use Perplexity to find and verify, then Claude or ChatGPT to write or build.
Is Perplexity Pro worth $20/month?
Yes, if research is a regular part of your workflow. Unlimited Pro Search, model choice across major frontier models, and file upload cover most professional research needs at the same price as ChatGPT Plus or Claude Pro. If you only do occasional lookups, the free tier is genuinely capable and worth starting with.
Which AI models does Perplexity Pro include?
Pro subscribers can switch between Perplexity's own Sonar model and major frontier models from OpenAI, Anthropic, and others — Perplexity adds new ones as they're released. This model flexibility is one of Pro's most distinctive features — you're not locked into a single underlying model for every search.
What can Perplexity not do?
Perplexity is not built for long-form writing, coding, or creative tasks — it will produce responses, but quality trails Claude and ChatGPT significantly on those use cases. It also lacks persistent memory across sessions in the way dedicated AI assistants do. Think of it as a research specialist, not a general-purpose AI.
Who should NOT use Perplexity?
Teams that primarily need an AI for drafting content, writing code, or creative work will find more value in Claude or ChatGPT. Perplexity is a research-first tool — if your workflow is mostly writing and building rather than finding and verifying, another tool is a better primary choice.
