The Verdict
Grok is built for x users and researchers, with a focus on chat and web-search. Perplexity targets researchers and knowledge workers and leads with ai-search and source-citations.
Pricing is close: Perplexity starts at $20/mo versus $22/mo for Grok — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Perplexity edges out on user ratings (4.6 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Grok offers broader built-in capabilities (7 features vs 6), while Perplexity takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Perplexity has a slight overall edge — but if real-time access to x posts and trending topics matters most to you, Grok may still be the right call.
