The AI answer engine — research with cited sources.
Perplexity reimagined search as conversation: ask a question, get a direct answer with citations to real sources you can verify. It is what Google feels like it should have become — fast, sourced, and free.
For research, fact-checking and staying current, it has become the daily driver for millions who are tired of SEO-spam search results.
Free
Completely free to use — no paid tier required as of 2026.
Researchers, students, journalists and anyone who wants fast, sourced answers instead of ten blue links.
Perplexity is the research tool the modern web needed. For factual questions, it beats traditional search — and the free tier is genuinely useful.
Scores reflect hands-on testing across the four criteria above, relative to the tool’s pricing tier. Last updated: September 24, 2026
