Perplexity
An AI answer engine that searches the web and cites its sources.
Perplexity takes a different approach from the other assistants on this list. Instead of a general-purpose chatbot, it’s built as an “answer engine” — you ask a question, it searches the live web, and it gives you an answer backed by citations you can click and verify.
That focus on sourcing is its defining strength. For research, fact-checking, or any question where you need to know where the answer came from, Perplexity is hard to beat. It also routes queries between top models from different providers, so you get the best available model for each task without locking into one ecosystem.
The trade-offs: it’s less suited to open-ended creative work than a full chatbot, and its Deep Research feature is now capped at 20 uses per month, making it better for sourced search than heavy report generation. For quick, verifiable answers, though, the free tier alone is genuinely useful.

Frequently asked questions
What makes Perplexity different from ChatGPT?
Perplexity is built as an answer engine rather than a general chatbot. Every answer is backed by a live web search and includes citations you can click to verify, which makes it especially good for research. ChatGPT is more of an all-rounder for writing, creativity, and conversation.
Is Perplexity Pro worth it?
If you do a lot of research, yes. Pro at $20 a month unlocks the best models, more Pro searches, and multi-model routing so each query goes to the strongest model. Note that Deep Research is capped at 20 uses per month, so it's best for sourced search rather than heavy report generation.
Does Perplexity cite its sources?
Yes — citations are Perplexity's defining feature. Every answer includes inline links to the web pages it drew from, so you can check the original source rather than trusting the AI blindly. This is why it's popular for research and fact-checking.
