Accuracy
We don’t publish our own scores. These are two widely cited independent studies; both tested news answers.
EBU and BBC · October 2025
Of four assistants tested (ChatGPT, Copilot, Gemini, Perplexity), Gemini performed worst. Across all four, 31% of answers had missing or misleading sources.
Lower is better. The public summary didn’t give a Perplexity-only figure.

FAQ
For research and fact-checking, Perplexity is usually the better fit because it searches the web and cites sources on every answer. Gemini is better if you work in Google’s apps, use Android, or want images and video. Many people use both.
In a 2025 European Broadcasting Union and BBC study of news answers, Gemini had significant issues in 76% of responses, the worst of four assistants tested. In the Tow Center’s 2025 citation test, Perplexity had the lowest error rate of eight tools at 37%. Both still make mistakes, so check the sources.
They cost about the same ($20 vs $19.99 a month). Perplexity Pro is better for research and gives access to models from several companies. Google AI Pro adds 5 TB of storage, Gemini in Gmail and Docs, Chrome auto browse and more, so it’s better value if you use those.
Gemini shows source links on some answers and offers a “Double-check response” button that highlights statements and finds supporting or conflicting results on Google. Perplexity shows numbered citations on every answer by default.
