Perplexity
AI-powered search engine that answers questions with cited sources instead of showing a list of links.
What is Perplexity?
Perplexity is an AI search engine that gives you direct answers with citations instead of a list of blue links.
It searches the web in real-time, synthesizes information from multiple sources, and presents it as a conversational answer with numbered citations you can click through.
Most builders use it for quick research, competitive analysis, and finding technical docs without sifting through SEO spam. It's faster than piecing together info from multiple tabs and better for current events than ChatGPT since it searches live web data.
Free tier gives you basic searches. Pro ($20/month) unlocks GPT-4, Claude, and unlimited Pro searches that dig deeper across more sources.
