Perplexity is the AI answer engine that shows its sources — and the free plan is genuinely useful. Here's what Pro really costs and the free alternatives worth trying.
Perplexity is an AI-powered answer engine that searches the web and answers with cited sources — the format that made it famous. The free plan is genuinely useful: standard search works for most everyday questions, with a limited number of advanced "Pro Search" queries per day. Pro is $20/month (or $200/year) — a stable price for years — and unlocks unlimited Pro Search, stronger models and file uploads. If you just want sourced answers occasionally, the free plan is enough. For research-heavy work, Pro is one of the best-value subscriptions in AI.
Perplexity is an AI answer engine: ask a question and it searches the web in real time, then writes an answer with numbered citations you can click to verify. Unlike a chat model, it's built for current, sourced information — prices, news, comparisons, technical facts.
Launched in 2022, it became one of the most popular AI search products and helped define the "answer engine" category that Google's AI Overviews and ChatGPT search later copied. It also powers the "Deep Research" style of multi-step searching for complex questions.
Based on long-stable public pricing (confirm on the official site):
Free: standard sourced answers unlimited, limited Pro Search per day
Pro: $20/month (or $200/year) — unlimited Pro Search, best models, file uploads
Enterprise: custom pricing for teams
Pro pricing has stayed at $20/month for years; always confirm current plans on perplexity.ai.
The free plan is one of the most usable in AI — you can genuinely research everyday questions without paying. Pro mainly matters for heavy users: researchers, journalists, students and anyone doing many advanced searches a day.
