Our verdict

Perplexity Pro has genuinely replaced traditional search for many knowledge workers. The citation-first approach builds trust that other AI tools lack, and Deep Research delivers comprehensive reports that would take hours to compile manually. Test the generous free tier to see if it transforms your research workflow — most users report it does.

Pros
  • Every answer includes citations with linked sources — verification built into the workflow
  • Deep Research mode generates comprehensive, multi-source reports on complex topics
  • Multi-model access: GPT-4o, Claude, Gemini available depending on task type
  • Comet Browser (launched mid-2025) integrates AI search directly into web browsing
Cons
  • Free tier has daily query limits that restrict heavy research sessions
  • Not optimized for creative writing, code generation, or tasks that don't need citations
  • Max plan at $200/mo is expensive for individual users wanting unlimited access
