The verdict
Perplexity combines real-time web indexing with LLM summarization and numbered inline citations, sidestepping the hallucination problem of standalone chat models by grounding every answer in live sources. The free tier handles most everyday research queries with no hard daily cap on basic searches. The Pro plan at $20/mo unlocks access to GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro as selectable backends, plus 600 daily Pro searches. Focus modes for academic papers, Reddit threads, and YouTube narrow results usefully for domain-specific queries. Answers occasionally misread or oversimplify source material, and the citation list can surface low-authority or paywalled pages alongside strong ones.
What works
- ✓Every answer includes numbered inline citations linking to the actual source URLs
- ✓Pro plan lets you switch between GPT-4o, Claude, and Gemini on a per-query basis
- ✓Academic, Reddit, and YouTube focus modes cut noise for domain-specific research
- ✓Free tier is genuinely functional with no registration required for basic queries
What doesn't
- ✕Occasionally misinterprets or over-condenses source material, especially for nuanced topics
- ✕Citation quality varies and can surface low-authority or paywalled pages prominently
- ✕No persistent memory or project context across sessions on the free tier
