Why does Perplexity give me wrong answers sometimes?
Perplexity uses large language models (LLMs) which occasionally 'hallucinate'—generating plausible-sounding but false information. Studies show 5-12% of Perplexity responses contain factual errors. This happens because LLMs predict likely text sequences rather than retrieving verified facts. Always verify critical claims (medical, financial, legal) against primary sources or Google's indexed results. Perplexity does cite sources, but the synthesis itself may misinterpret or combine sources incorrectly.
Not for all users. Perplexity excels at synthesizing summaries and answering direct questions, but lacks Google's exhaustive indexing. Google indexes 200+ trillion pages; Perplexity accesses real-time web content but cannot browse the entire index. For finding niche websites, obscure historical documents, or specific product pages, Google remains superior. Many users use both: Perplexity for quick answers, Google for deep research.
Perplexity's Academic Mode returns peer-reviewed papers with direct citations, making it faster for literature reviews. However, Google Scholar (Google's academic tool) indexes 389 million scholarly articles with more granular filtering. For PhD-level research, Google Scholar is more thorough. For undergraduates wanting quick background summaries before diving into papers, Perplexity is faster. Ideally, use Perplexity to identify relevant topics, then Google Scholar to find primary sources.
Does Google have an AI answer tool like Perplexity?
Yes. Google Gemini (integrated into Google Search) now provides AI-generated summaries called 'AI Overviews' in search results. However, Gemini is still rolling out globally and is less refined than Perplexity. Google's traditional search results remain primary. Additionally, Google's approach embeds AI answers within search rankings, whereas Perplexity is a dedicated AI-first experience, making Perplexity more conversational and citation-focused.
Google Search returns results in ~0.8 seconds but requires you to click and read. Perplexity takes ~2.1 seconds to generate a complete answer, but you have a ready-made summary immediately. If speed is measured as 'time to information consumption,' Perplexity saves 60-70% reading time for direct questions. Google wins on raw server response speed but Perplexity wins on overall answer delivery time.
