Perplexity AI Pro Review: The Research Assistant That Actually Cites Its Sources
Perplexity AI has positioned itself as the AI-powered alternative to Google for research tasks — and in 2026, it has genuinely earned that positioning. The Pro tier adds access to GPT-4o, Claude 3.7, and the company own Sonar models with real-time web retrieval and a focus on cited, grounded answers.
What Sets It Apart
Every response in Perplexity Pro includes numbered citations linked to the original source. For fast-moving technical topics like AI research, this is invaluable — you can immediately verify claims rather than trusting the model blindly. The Spaces feature allows you to create persistent research threads with custom instructions, making it excellent for ongoing investigation projects.
