Perplexity or ChatGPT? Two sources point different ways on research

AI-generated from the sources listed, with automated source checks.

Two comparisons disagree on which AI tool is best for research. One recommends Perplexity, while ChatGPT won the research task in the other.

Should you use Perplexity or ChatGPT when you need to find and verify information? The answer depends on who you ask. Two comparisons reach different conclusions.

Two different winners

The blog Cut The SaaS, which advises on software, concludes that Perplexity is the best choice for structured research with source citations. According to the blog, the quality of the sources and the consistency of the citations are higher than with ChatGPT. The blog is based on the vendors' product pages and the authors' own use. It does not describe an independent testing method.

Analytics Vidhya has a comparison, last updated September 12, 2025, that is a more hands-on test with specific tasks. On the research task, ChatGPT won. According to Analytics Vidhya, ChatGPT provided all the relevant links, which made the answer easier to understand and verify. Perplexity's format seemed appealing at first, but it lacked key links to research papers.

Different tools

Perplexity is built as a search engine with real-time access to the web and shows source citations on its answers. In ChatGPT, web search is a tool it can use.

For broader use, Cut The SaaS concludes that ChatGPT is strongest. That includes voice, image generation, custom GPTs (your own versions of ChatGPT for specific purposes) and the ecosystem of features surrounding the tool.

What does it cost?

Perplexity Pro costs USD 20 per month or USD 200 per year. ChatGPT Plus costs USD 20 per month. Both providers also offer a more expensive tier at USD 200 per month.

Cut The SaaS recommends paying for both if you do serious research and also use AI broadly. The combined price is about USD 40 per month, which is less than the most expensive ChatGPT subscription.

What does it mean for you?

The two sources disagree, and one of them is based primarily on the authors' own experience. So always check the links an AI tool gives you, no matter which one you choose. Also check prices on the providers' own sites before you subscribe.
