Claude VS Perplexity

Strengths

• ✓Unmatched for long-form writing, document analysis, and complex multi-step tasks
• ✓200K context window handles full books, contracts, and large codebases
• ✓Best instruction-following in the industry for nuanced, structured outputs

Weaknesses

• ✗No real-time web access — knowledge cutoff means stale information for current events
• ✗No built-in citation or source attribution

Strengths

• ✓Real-time web retrieval with cited sources — eliminates hallucination risk for facts
• ✓Free tier offers unlimited basic searches — very accessible entry point
• ✓Excellent for academic literature discovery and fact-checking workflows

Weaknesses

• ✗Not useful for writing, coding, analysis, or any generative task beyond search
• ✗Answers are constrained by what exists on the web — can't synthesise or reason beyond it
