Perplexity Review
Overview
Perplexity is an AI-powered answer engine that reimagines search for the AI era. Instead of returning a page of links, it synthesizes information from multiple sources into a clear, concise answer with inline citations. It combines the speed and accuracy of search engines with the conversational intelligence of large language models, making it ideal for research and fact-finding.
Key Features
- Source-Cited Answers: Every response includes numbered inline citations linking back to the original sources, so you can verify claims and explore further.
- Multiple AI Models: Choose from GPT-4o, Claude Sonnet, Perplexity's own sonar models, and more, letting you pick the best model for your query type.
- Pro Search: An advanced mode that asks clarifying questions, performs multi-step research, and produces comprehensive answers on complex topics.
- Spaces & Collections: Organize your research into themed spaces with custom instructions, file uploads, and shared collaboration for team workflows.
User Experience
Perplexity's interface is purpose-built for information retrieval. The search bar is front and center, and results appear instantly with a clean layout showing the AI-generated answer alongside source cards. The citation system is excellent, with numbered references that you can click to see the exact source passage. This makes it far more trustworthy than chatbots that provide unsourced answers.
The follow-up question flow feels natural, letting you drill deeper into topics without losing context. The Pro Search feature is particularly impressive for complex queries, breaking down your question into sub-queries and synthesizing a thorough response. The Discover feature surfaces trending topics and popular questions. The mobile app is well-designed and fast, making it a genuine Google replacement for quick lookups.
