What is GPTZero's source finder?

GPTZero source finder is to detect potentially misleading claims in text and give recommendations for sources that support or contradict those claims. Our tool allows you to find any arguments or “claims” in a document that may require more scrutiny, and then links to helpful sources to dive deeper into your analysis and provide helpful context. You can pull these into your own research, or share your results to improve someone else's.

How do I use GPTZero's source finder?

Simply paste in the text you want to check, or upload your file. Source finder will detect as many checkable, objective claims in your text and match those to sources from online, academic, and publicly available data coming from AI-powered search engines. You may find sources that would directly support or contradict these claims. You can cite the relevant snippet from the source, and also citations in MLA, Chicago, APA, Bibtex and IEEE.

While this feature is in beta, there may be changes and improvements made to the feature that may change the functionality upon final release.

Does GPTZero's source finder use AI?

We use AI to detect claims and arguments and pair them with potentially relevant sources. We actively do NOT recommend AI-generated content, due to their unreliability, and filter out sources that are potentially AI-generated.

Does GPTZero's source finder work as a fact checker?

Our tool currently does not take a stance on whether your claims or the claims in the sources cited are true “facts” or false. We only indicate whether there is online evidence that contradicts, debates, or supports a claim. We strive to only include high-quality sources from reputable online, academic, and public sources, but do not endorse the viewpoints in any specific source.

How does GPTZero select the sources in its database?

We allow you to search for claims from a dataset of over 220M scholarly articles, preprints and real-time news using AI next-generation recommendation AI and large language models.
