abstract: Perplexity is a real-time AI search engine with live web access and cited answers, ideal for research and fact-checking. DeepSeek is a free, open-source LLM optimized for coding and mathematics but lacks real-time web data and citations, making it riskier for information-sensitive tasks.

conclusion text: Choose Perplexity if you need current information, verifiable citations, or work with sensitive data — its real-time web access and transparent sourcing make it essential for research, fact-checking, and professional use. Choose DeepSeek if you're a developer, mathematician, or budget-conscious user prioritizing coding tasks and reasoning — its free access and open-source nature are unmatched, but avoid it for information requiring today's data or sensitive business contexts.

main entity: Is DeepSeek safe for business or confidential work?
  type: Question
  accepted answer: Answer
    text: DeepSeek carries significant security risks for confidential tasks. It has no real-time web access and cannot verify current information — and as a Chinese-built tool, there are legitimate data privacy and government access concerns. For proprietary code, client data, sensitive research, or business-critical information, Perplexity is substantially safer due to its US-based infrastructure and transparent data handling.
    language: en-US
main entity: Can I use DeepSeek for current events or breaking news?
  type: Question
  accepted answer: Answer
    text: No. DeepSeek relies on its training data cutoff and cannot access real-time web information. Any answer about recent events, market data, or breaking news will be outdated or inaccurate. Perplexity, with live web search and citations, is the clear choice for current information needs.
    language: en-US
main entity: Which is better for coding and math problems?
  type: Question
  accepted answer: Answer
    text: DeepSeek excels at both coding and mathematical reasoning tasks. Its advanced reasoning capabilities and architecture specifically optimize for these domains. Perplexity can handle coding questions but lacks the specialized strength DeepSeek offers — and for comparison, ChatGPT's coding performance sits between the two.
    language: en-US
main entity: How much does each tool cost?
  type: Question
  accepted answer: Answer
    text: DeepSeek is 100% free with no paywalls or premium tiers. Perplexity offers a free tier with limited searches, and Pro costs $20/month for unlimited searches and advanced features. If cost is the only factor, DeepSeek is unbeatable — but for most professional use cases, Perplexity's subscription cost is justified by real-time data access.
    language: en-US
main entity: Why doesn't DeepSeek have real-time web access?
  type: Question
  accepted answer: Answer
    text: DeepSeek is optimized as a large language model for reasoning, coding, and language tasks rather than as a search engine. Adding real-time web access requires different infrastructure and indexing architecture — which Perplexity was specifically built to do. DeepSeek's design prioritizes compute efficiency and reasoning depth over real-time information retrieval.

claim reviewed: DeepSeek vs Perplexity
review body: Perplexity is a real-time AI search engine with live web access and cited answers, ideal for research and fact-checking. DeepSeek is a free, open-source LLM optimized for coding and mathematics but lacks real-time web data and citations, making it riskier for information-sensitive tasks.
