What AI models are used in Paperpal?

Paperpal employs a variety of AI models best suited to specific features. We also use our own proprietary suite of specialized AI and generative AI models trained on scholarly data. Irrespective of the model, your privacy remains paramount so rest assured that customer data is secure and never used to train any of the AI models.

Will my Paperpal edited document be flagged as plagiarised?

At a document level, unless the original manuscript has been copied, it is very rare that it will be flagged by the plagiarism checker tools. Also, at a sentence level, there is a low possibility that text generated by Paperpal will get flagged by a plagiarism checker. However, as the rewrites suggested by Paperpal follow standard academic sentence construction, there is a chance that a tools like Turnitin might pick individual sentences as resembling published literature.

Will my Paperpal edited document be flagged by AI detectors?

Being flagged by AI detectors isn’t necessarily a bad thing. Many authors use AI tools to improve writing and productivity. AI detectors promote accountability to ensure content is reliable. Understand the AI scoring, and then use Paperpal’s output as a base to refine the text and express ideas in your style. Secondly, note that AI detectors are in the early stages of development. For example, one AI detector falsely claimed the US Constitution was written by AI. Therefore, these detectors can be used as a reference, but should not be relied on for an accurate assessment.
