What Is Perplexity?
Perplexity is a web-grounded AI answer engine. Unlike ChatGPT's default chat (which relies on training data) or Google (which returns links), Perplexity runs live web searches, reads the top results, and synthesizes a cited answer. Every factual claim links back to the source, so you can verify in one click.
Why Knowledge Workers Are Using Perplexity in 2026
Perplexity CEO Aravind Srinivas disclosed in a February 2026 podcast with Lenny Rachitsky that the platform hit $150M ARR and handles over 500 million monthly queries. Similarweb data for Q1 2026 showed Perplexity traffic grew 87% year-over-year while generic search engines grew flat. A Pew Research 2026 study of US journalists found 34% now use Perplexity daily — ahead of every other AI tool.

FAQs
Is Perplexity replacing Google?
For research, often yes. For navigational queries (find a site), Google is still faster.
Are citations always accurate?
Usually, but always verify — Perplexity occasionally misattributes.
Does Perplexity train on my queries?
Free tier queries may be used to improve the service; Enterprise queries are not.
What models does Perplexity use?
Their in-house Sonar models by default, with Pro access to frontier models from Anthropic, OpenAI, and Google.
Can I trust it for legal or medical research?
Use it as a starting point; never as the sole source for professional advice.
