Instead, he described how Perplexity summarizes web content and emphasized its citations, while acknowledging that citation precision was not perfect.
What happened onstage?
Coldewey put the question to Srinivas during a Disrupt Stage interview focused on publisher concerns about Perplexity’s use of online material. The event clip’s description preserves the question as: “What is your company’s definition of plagiarism?” TechCrunch’s report of the interview says Srinivas did not define the term in response.
Rather than set out a standard for plagiarism, Srinivas described the product’s process. He said it is “surfacing content from the web, summarizing it in a manner that the user can digest,” and compared the work to what journalists, academics, and students do. He also said Perplexity “always cites its sources” and does not claim ownership of the material it displays. Those are Srinivas’s descriptions and claims, not a verified guarantee about every answer.
On citations, he said, “At the end of every sentence, there’s a footnote or the corresponding page for where it’s truly information from,” then added: “Of course, it’s not, like, extremely precise … but we’re trying our best to do those kind of things.” The qualification matters: his answer itself acknowledged that citation precision could fall short.

The exchange took place amid publishers’ complaints that AI summaries may reproduce or closely track their reporting. The concerns included whether summaries give readers sufficient attribution, whether they divert traffic from publishers, and whether they substitute commercially for the original work. TechCrunch reported that Dow Jones and the New York Post had sued Perplexity by the time of the interview, and that The New York Times had sent a cease-and-desist letter earlier that month. Those reports describe disputes and claims, not findings that plagiarism or unlawful copying occurred.
Two related questions are easy to conflate:
- Plagiarism concerns attribution and presentation: whether work or ideas are presented in a way that misleads readers about their source.
- Copyright infringement is a legal claim about the use of protected expression under applicable law. Its resolution depends on the facts and legal proceedings; it is not settled simply by whether citations appear.
The interview coverage documents the question and Srinivas’s response, but it does not establish a definitive legal definition of plagiarism or determine whether Perplexity’s conduct violated copyright law.
What did the reported plagiarism-detection figures show?
TechCrunch reported results from a 2024 Copyleaks detector report involving two Perplexity summaries. These figures describe those examples only:
| Example reported | Detector result | What the number means |
|---|---|---|
| One summary based on a Forbes article | 48% of the summary’s text identified as paraphrased | A result for one tested summary, as reported by TechCrunch from Copyleaks; not a rate for Perplexity answers generally. |
| A second summary | 28% paraphrasing and 7% plagiarism | The “plagiarism” figure uses Copyleaks’ own definition and applies to this tested example. |
These detector results are not a representative measurement of all Perplexity outputs, a universally validated measure of plagiarism, or a court finding. They should not be used to infer how often other answers may reproduce or paraphrase source material.
What happened in the later publisher disputes?
TechCrunch reported in October 2024 that Dow Jones and the New York Post sued Perplexity, alleging copyright violations and copying of their material. A later TechCrunch report says The New York Times filed a copyright-infringement suit against Perplexity in December 2025. The cited coverage establishes that these suits were filed; it does not establish their eventual outcomes. It is therefore more accurate to describe the claims as allegations than as proven violations.
These legal disputes are separate from the onstage question. A lawsuit alleging copyright infringement does not itself establish plagiarism, and a company’s citation practices do not by themselves decide whether its use of material is lawful.
