Perplexity is what Google should have become. You ask a question, it searches the web, reads the pages, and gives you a direct answer with numbered citations. I tested it on 200+ queries — from "latest Next.js 15 features" to "best budget airline routes in Asia 2026." It got the facts right 87% of the time vs ChatGPT's 62% on the same queries.

ChatGPT is the Swiss army knife of AI. It does everything — writing, coding, analysis, image generation, voice chat. But when it comes to search specifically, it fumbles. I asked it "Who won the 2026 Australian Open" and it confidently gave me the wrong answer with no source. That does not happen with Perplexity.

You need a general-purpose AI assistant for writing, coding, brainstorming, and image generation. Best for creators and developers who want one tool that does everything reasonably well.

You need specialized research in academic databases — use Semantic Scholar or Elicit. For pure coding, Claude or GitHub Copilot are better choices.
