A PDF itself cannot reveal whether it was AI-generated. Most PDF files don’t contain information that directly identifies whether the content was written by AI.
To assess authorship, you’ll need to analyze the text itself for common AI-writing patterns or use a tool such as Quillbot’s AI Detector to evaluate the content.
ChatGPT is safe to use for school when students follow these precautions:
Another way to use ChatGPT safely is by using Quillbot’s free AI Content Detector or AI Detector Mobile App for iOS to ensure that AI-assisted writing hasn’t been plagiarized.
ChatGPT was first released on November 30, 2022.
Since then, various updated versions have been released, like ChatGPT-4 on March 14, 2023 and ChatGPT-4.5 on February 27, 2025.
OpenAI, the company that created ChatGPT, is working on new versions for future release.
Yes, AI can write a book. However, a book written by AI probably wouldn’t be a very good book.
Unlike humans, AI is limited when it comes to creativity (e.g., with figurative language), themes, and tone of voice.
Despite this, generative AI can be helpful to human authors. For example, AI can suggest writing strategies to put writers in the right mindset. It can also be used for parts of the writing process. For example, if you’re brainstorming ideas for your own book, the Quillbot AI book title generator can instantly suggest creative, attention-grabbing titles to spark inspiration.
If you use it more extensively, generative AI can be used in combination with a tool that can humanize AI text to improve the style. However, it’s good to be aware that many publishers also use AI detectors to check that what they publish is high-quality, human-written work.
If you’d like to see how AI detectors work, you can try the Quillbot AI Detector.
AI-generated content can be revised, paraphrased, or combined with human input, making it more difficult to identify through manual review alone. In such cases, it’s helpful to use multiple verification methods.
For example, you can analyze the text with Quillbot’s AI Detector to assess potential AI involvement and use Quillbot’s Plagiarism Checker to identify any content that may closely match existing online sources. Together, these tools can provide a more comprehensive evaluation of a document’s authorship.
Using AI to rewrite text can be a quick and easy way to improve clarity, tone, or structure, depending on what you need. You can then use a humanizer tool, like Quillbot’s, to humanize AI text so it reads more like something a person would actually write.
If you’re unsure whether the final version still feels too “AI-generated,” Quillbot’s AI Detector can also help you check the text before you share it.
