Perplexity vs ChatGPT: which is better for studying?

Use Perplexity when you need current facts with a clickable source, for example to find papers or check a claim. Use ChatGPT when you need to learn, because study mode quizzes you and it reads your notes. For exam prep, ChatGPT is the better default. Neither knows your lecture unless you upload it. To be tested only on your own slides, StudyPDF is a third option.

More on this

Perplexity is an answer engine. It searches the web for each question and puts citations next to the answer. ChatGPT, from OpenAI, is a general assistant that explains, writes, codes and makes images, and it searches the web when a question needs it. Both read files you upload and run on web, desktop and phone. The models underneath change every few months, so this page compares the tools around them. Perplexity Pro lets you pick between models from several makers; ChatGPT uses OpenAI's own.

For studying, the two differ in what they are built to do. ChatGPT has study mode on every plan: it asks questions, gives hints and can quiz you one question at a time, though not inside Projects. Perplexity has Learn Mode for verified students and an Academic filter for papers. Prices are close: Perplexity Pro is $20 a month ($17 billed yearly) and verified students pay $10 a month for Education Pro; ChatGPT Plus is $20 and Go is $8.

A routine that uses both: find and check sources in Perplexity, then learn the material in ChatGPT's study mode. A citation is a link to a web page, not proof that the answer is right, so open the source before you rely on it. Neither tool keeps track of what you know across a whole course; that part is up to you.

Questions and answers

Is Perplexity better than ChatGPT for studying?

It depends on the job. Perplexity is better for finding sources and checking facts, because every answer comes with citations. ChatGPT is better for learning a topic, because study mode asks you questions, gives hints and can quiz you. Many students use Perplexity to find sources and ChatGPT to study. Both have free plans, so try the same question in each.

What is the difference between Perplexity and ChatGPT?

Perplexity is built around web search: it looks things up for each question and shows its sources. ChatGPT is a general assistant that writes, codes, makes images and explains, and it searches the web only when a question needs it. That makes Perplexity stronger for current facts and ChatGPT stronger for open-ended work.

How much do Perplexity and ChatGPT cost?

As of October 2026 both have a free plan. Perplexity Pro is $20 a month, or $17 a month billed yearly. ChatGPT Plus is $20 a month, the cheaper Go plan is $8 a month, and ChatGPT has no yearly billing. Both sell higher tiers for heavy use, and prices can differ by country.

Is there a student discount for Perplexity?

Yes. Verified students and educators can get Education Pro for $10 a month after a SheerID check. It includes everything in Pro plus Learn Mode. ChatGPT's study mode is on every plan, including the free one.

Is ChatGPT worth $20 a month for a student?

Often not at first. The free plan already has study mode, web search and file uploads, with limits. Pay when you keep hitting those limits, for example in exam weeks, and try the cheaper Go plan before Plus.
