Perplexity vs ChatGPT for Research: Which Gives Better Sources?

We submitted 25 research questions to both. Perplexity cites sources; does that mean it is more reliable?

What We Tested

Our testing methodology involves running standardized tasks across multiple reviewers to eliminate individual bias. For this article, we focused on practical use cases that represent how real users actually use these tools in their daily workflows — not cherry-picked demos designed to flatter either product.

All testing was conducted independently by the AICompare editorial team. No tool provided payment or compensation in exchange for coverage or favorable treatment. Our full testing methodology is available at aicompare.online/methodology.

Our Findings

We submitted 25 research questions to both. Perplexity cites sources; does that mean it is more reliable? Our independent testing found meaningful differences across key use cases that matter to most users. The winner in our testing was determined by aggregate performance across all test categories rather than a single standout metric.

We evaluated each tool across output quality, speed, ease of use, consistency, and value for money. Individual results may vary based on specific use cases, as these tools often perform differently depending on the domain and complexity of the task.
