Our Verdict
Perplexity wins
Use Perplexity ($20/mo Pro, ~$17/mo annual, usable free tier) when your question is "what is true and where is it from": every answer ships with citations by default, and its 37% source-attribution error rate is the best measured among AI search tools (Tow Center, 1,600 queries). Use ChatGPT Plus ($20/mo) when your question is "turn this into work": better writing, coding, file analysis, memory, images and agent tools for the same monthly price. Only one subscription? Most people should take ChatGPT and use Perplexity's genuinely useful free tier for sourcing.
