The price difference, in detail

Without a student price, Perplexity Pro is $17 a month billed annually and ChatGPT Plus is $20 a month with no annual option. Both have a top tier for heavy users at $200 a month (Perplexity Max and ChatGPT Pro), and ChatGPT also has a $100 Pro step in between.

Perplexity's Education Pro is for students and faculty at university-level institutions who verify through SheerID, and your Perplexity account email does not have to be a school address. ChatGPT's offer is limited to eligible US degree-granting institutions and renews at $20 a month unless you cancel. One catch for India: Perplexity bills only in USD there, while ChatGPT sells its Go plan at ₹399 a month.

Which one fits you

Pick Perplexity if you are a student or faculty member anywhere it verifies you, and mostly need researched answers with sources.
Pick ChatGPT Plus if you are an eligible US college student who can claim the four months at $0, or you need images and file work more than citations.
