Perplexity
AI search engine with cited sources
What is Perplexity?
Perplexity is less of a general-purpose AI assistant and more of a research engine — the thing you open when you need a fast, sourced answer to something you'd otherwise spend 15 minutes Googling. It searches the web in real time, synthesizes what it finds, and shows you numbered citations inline. Clicking them takes you directly to the source. That workflow is genuinely faster than opening multiple tabs and reading four articles yourself.
The free tier is more generous than most competitors — you can run unlimited basic searches without a subscription. The tradeoff is that the best underlying models (GPT-4o, Claude) are locked behind the Pro tier. Even so, Perplexity's standard model gets the sourcing right often enough to be a daily-use tool for researchers and anyone who needs to verify claims quickly.
What it's good at
- Cites sources inline — you can verify every claim without opening a new tab for each one
- Real-time web search as the default, not an add-on feature
- Genuinely fast for research questions where you need current, verifiable information
- Good at synthesizing multiple perspectives on a topic without picking sides
Where it falls short
- Not a writing assistant — if you want polished prose, you'll need to take the research output into Claude or ChatGPT
- Creative tasks are genuinely outside its wheelhouse; it's not what it's built for
- The best model quality requires Pro — the free tier uses a weaker underlying model that occasionally misses nuance

Who should use it
Perplexity is the right tool if your primary workflow is research — fact-checking, monitoring a topic, or quickly understanding something you know nothing about. Journalists, students, analysts, and anyone who regularly asks "what's the current state of X" will find it faster and more trustworthy than asking a general AI assistant. If you need to actually write something afterward, you'll still want Claude or ChatGPT for that step.
Trending signal
Perplexity is one of the clearer rising trends in the AI tools space. As people have become more skeptical of AI hallucinations, the appeal of a tool that shows its sources has grown noticeably. Search volume is up, and the product keeps shipping — Spaces, file uploads, and better model options have all landed in the past year. The score of 79 reflects genuine momentum from users who've realized that ChatGPT isn't actually the right tool for research questions.
