Perplexity vs Google
AI search vs traditional search — honest comparison
Perplexity sits at the intersection of search and AI. These articles cover the free tier, Pro subscription, API, and how it stacks up against both traditional search and AI chatbots.
Perplexity combines large language models with real-time web search to produce cited, sourced answers. Unlike traditional chatbots, every response includes inline citations with links to original sources. Free tier covers unlimited quick searches.
Pro at $20/month unlocks unlimited Pro searches using the latest models (GPT-4o, Claude, and Perplexity's own models). The API offers search-grounded completions for developers building applications that need real-time factual answers.
