Perplexity vs ChatGPT
Verified 2026-07-18 by Michael Okeje
Perplexity and ChatGPT solve slightly different problems. Perplexity is an AI answer engine that searches the live web and cites its sources, which makes it strong for research. ChatGPT is a general assistant with a broad tool ecosystem. Both paid tiers are around $20/month, but ChatGPT has an $8 Go plan and Perplexity has an Education Pro plan for verified students. Choose by task: cited research versus general-purpose help.
