For example, QuillBot’s AI Humanizer is an AI model designed to understand and refine AI outputs to make them sound more human.

This field is developing each day, so understanding what AI is and how it works is more important than ever.
How can you check if an image is AI generated?: There are a few ways you can check if an image is AI-generated.

First, review the image for anything that doesn’t look quite right. AI-generated images often have distorted text, patterns, or human features (especially faces and hands).

Second, check for metadata information. Some AI image generators use specific filenames or imprint a watermark on their images.

Third, understand how AI detectors work and how you can use them to analyze the probability that an image was generated by AI.

And if you need help detecting texts generated by AI, QuillBot’s free AI Content Detector is one option.
Can AI write a book?: 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. Or it can be used in combination with a tool that can humanize AI text to improve the style.

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.
Can AI write code?: Yes, AI can write code. That said, it is still quite limited in the quantity and complexity of code it can write.

AI can be helpful for writing basic code or for helping developers check for errors. But if you want to create an entire program or complex website, AI probably isn’t the best choice.

Keep in mind how AI detectors work: by evaluating how surprising and varied writing is. Since code is a very structured language and doesn’t contain these factors, it’s harder to tell if it was written by AI.

QuillBot’s free AI Detector can help you check if text was written by AI, but may not be good at detecting if code was written by AI due to the reasons above.
What are the rules on how to cite AI?: There are different rules on how to cite AI depending on your specific context.

You shouldn’t cite AI as a source of factual information. But if you’re studying AI, you may be able to cite it as a primary source. Understand how to cite sources in the style relevant to your industry or project, and then look at how the manual says to cite AI.

If you use AI in other ways (e.g., developing research questions), some institutions require you to cite it. Check your institution’s guidelines.

Educators understand how AI detectors work (like QuillBot’s Free AI Checker) and can detect AI writing, so it’s important to be clear in your citations.
How can I use AI for writing?: There are many opinions about how to use AI for writing, and these may vary based on the industry or subject matter at hand.

For example, AI copywriting may be acceptable, but in academic writing, you should avoid relying completely on AI to generate output. Educators know how to detect AI writing and may use an AI Content Detector.

You can use AI to help you brainstorm research questions or organize an outline. When you use AI in these capacities, check if your institution requires you to include it as a citation.

You can also use AI to humanize AI outputs in appropriate contexts.
What are some common AI words?: Some common AI words are:

Tapestry

Crucial

Intricate

Interplay

Elevate

Resonate

Enhance

Offerings

Leverage

Embark

Just because you see one of these words in a text doesn’t mean it was written by AI. But these words are commonly used when AI generates content.

If you’re learning how to detect AI writing, brushing up on common AI words is one way to do that.

You could use the QuillBot AI Detector to analyze writing and see if it looks like it was created by AI. You can also use our AI Humanizer to rephrase and refine the text.
What is the difference between AI and generative AI?: The difference between AI and generative AI is that traditional AI follows specific rules to perform a task, but generative AI creates new content.

The first type of AI included programs that made decisions based on rules (in the same way as a human expert), such as determining a person’s credit score.

A later development, machine learning AI, classifies or predicts outcomes based on patterns. An example of machine learning is Netflix recommendations that are based on your previous viewing habits.

Generative AI tools combine machine learning with natural language processing technology. They learn from underlying patterns and use that information to “decide” what details to include in a paragraph, image, or other output. Examples of generative AI tools that create new content include ChatGPT and Gemini.

Generative AI tools are useful for brainstorming, prewriting, and paraphrasing, but they should never be used for writing entire assignments.

QuillBot’s AI Checker Android App and AI Checker iOS App can help you ensure that the writing you submit for class assignments is based on your own writing voice and ideas.
How do you use generative AI for brainstorming and prewriting?: To use generative AI for brainstorming and prewriting, choose a generative AI tool (e.g., Gemini or ChatGPT), and type a prompt.

In your prompt, provide a brief description of the writing assignment and topic, and ask the tool to generate ideas for body paragraph topics. Place the description of your writing assignment in curly brackets.

Generative AI for brainstorming prompt example
I’m an English Composition student who is brainstorming body paragraph topics for the following assignment: {In an 800-1000 word essay, defend an argument for or against smartphone bans in U.S. public schools}. I would like you to generate a list of the pros and cons of smartphone bans. The list should cover benefits and drawbacks for students, schools, and educators.

After the generative AI tool responds to your prompt, review the list of body paragraph topics, and select the ones that you’d like to research further.

Use keywords from each item on the list as search phrases in an academic database or a search engine (e.g., smartphones and student distractions).

Then, research multiple ideas from the generative AI response in order to choose a main idea (e.g., your main argument) and body paragraph topics that are based on critical thinking.

When you’re in drafting stages of your writing task, QuillBot’s free Grammar Checker can help you avoid errors. QuillBot’s free Citation Generator can also help you create flawless citations for your outside sources.

QuillBot’s AI Detector Android App and AI Detector iOS App can help you ensure that the writing you submit for class assignments is based on your own writing voice and ideas.

Only access ChatGPT through the official app or website (not from any third-party vendor).

Stay informed about changes to OpenAI’s data and privacy policies.

Avoid sensitive personal information and confidential company data in prompts (e.g., clients’ real names, contact information, or financial records).

Verify facts provided by ChatGPT with credible sources.

Another way to use ChatGPT safely is by using QuillBot’s free AI Detector to ensure that AI-assisted writing hasn’t been plagiarized. QuillBot’s AI Humanizer tool can help you quickly and easily humanize AI outputs to improve the fluency of a text.
Is ChatGPT safe to use for school?: ChatGPT is safe to use for school when students follow these precautions:

Stay informed about potential risks such as ChatGPT plagiarism.

Review and follow your instructor and/or school’s policies about generative AI (e.g., Some schools require students to disclose when they’ve used ChatGPT for assignment help).

Avoid sensitive personal information in prompts (e.g., your name and contact information).

Verify facts provided by ChatGPT with credible sources.

Use ChatGPT for small pieces of an essay (e.g., a hook or thesis statement) or to brainstorm ideas. Don’t prompt ChatGPT to generate entire drafts.

Revise any content that ChatGPT generates to ensure the writing assignments you submit are in your own writing voice.

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.
Can I use ChatGPT for job applications?: Many job seekers use ChatGPT for job applications.

For example, you can include your cover letter along with the job description in a prompt that asks ChatGPT to add keywords that will increase your application’s chances of getting noticed by application scanning software.

You can ensure ChatGPT is safe for job applications with these strategies:

To protect your privacy, delete contact information and other personal details from application materials that you include in ChatGPT prompts.

Because recruiters often use AI detectors to check cover letters and resumes, always revise any text that ChatGPT generates in response to your prompts. QuillBot’s AI Humanizer tool can help you humanize AI outputs to match your preferred style.

Look closely at specialized terms in ChatGPT outputs in case the chatbot misused any terminology.

QuillBot’s AI Checker Android App and AI Checker iOS App can also help you ensure that your application materials reflect your own writing voice.
What are the ethics of AI art?: The ethics of AI art address the ethical consequences of generative AI tools that make images and videos. Some of the AI ethics that apply to art include the following

Bias and stereotyping: AI tools might generate images that echo the stereotypes that are represented in the data sets on which they’re trained.

Intellectual property: AI tools for art are often trained with the digital works of human artists without their knowledge or consent.

Deepfakes: AI tools can generate fake images of real humans (e.g., celebrities), which can be used to spread misinformation and harm people’s reputations.

Job displacement: AI-generated art could lead to fewer jobs or business opportunities for human artists.
What do teachers use to detect AI?: Teachers use a mix of strategies and tools to detect AI writing.

One method teachers use to detect AI is manual analysis. Teachers look at grammar, style, tone of voice, and the themes present in writing to see if it feels human.

Teachers also know how AI detectors work and how to use them to analyze writing. AI detectors can check—for example—essay writing to see if the qualities of the essay match human samples or AI samples.

QuillBot’s free AI Content Detector is one of the tools that can help teachers detect AI.

In contexts where the use of AI outputs is permitted, AI Humanizer tools can help humanize AI outputs and make the writing seem more natural and fluent.
What is artificial general intelligence?: Before understanding what artificial general intelligence is, you need to understand what AI is in the general sense.

AI refers to computer programs designed to perform tasks requiring human-level intelligence, but usually limited to specific tasks.

For example, QuillBot’s free Paraphraser can rewrite sentences, but it cannot compute numbers or guide a vehicle.

Artificial general intelligence (AGI) is a theorized AI that can perform any human task, with cognitive abilities and adaptability to apply knowledge across diverse areas.
What is AI governance?: AI governance is the frameworks, policies, and practices intended to ensure that AI is developed, deployed, and used in ethical and transparent ways. It is related to AI ethics.

AI governance differs by jurisdiction. If you are studying or working in this field, it’s best to consult with experts in your jurisdiction for more detailed information.

Specific institutions and organizations may also have their own form of AI governance. For example, many universities now have published policies about how students can and cannot use generative AI and how teachers should work with AI detectors.
What are AI hallucinations?: AI hallucinations are errors where AI generates false or nonsensical information. They’re most common in large language models (LLMs), image generators, and other generative AI models.

These hallucinations may appear confident and correct at first, but closer inspection can reveal inaccuracies.

For example, an AI-generated image may look good overall, but details like hands or text may not be accurately generated. Or if you ask AI to provide information and cite sources, it may accurately relay the information, but cite a source where that information doesn’t appear.

Understanding what AI is helps explain why AI hallucinates. AIs are computer programs trained on datasets. Biases, gaps, inaccuracies, and ambiguities in this data can cause hallucinations.
What are AI agents?: AI agents are software programs that can perceive their environment. They can gather data, analyze it, and take action, working autonomously to achieve specific tasks.

A few examples of AI agents are:

Self-guided vehicles

Delivery drones

Virtual assistants like Siri or Alexa

Customer service chatbots

An AI chess opponent

AI agents are one of the many types of AI (generative AI, analytics programs, AI detectors, etc.) and are quite common in modern society given their ability to help humans with everyday tasks.
How do I check if AI wrote something?: The simplest way to check if AI wrote something is to use an AI detector. QuillBot’s free AI Content Detector analyzes what percentage of text is AI generated and what percentage is AI refined.

You can also manually analyze the language and content of a text to determine if it’s likely that AI wrote it. AI-generated content is sometimes characterized by predictable word choice and sentence structure and a stiff, formal tone.

Whatever method you use to detect AI writing, keep in mind that no approach is 100% reliable. A detailed report like the one provided by QuillBot’s AI Content Detector can provide more context for making decisions.
How do I spot AI-generated text?: One easy way to spot AI-generated text is to use an AI detector, which analyzes text features to determine whether they are more similar to human-written or AI-generated samples.

You can also sometimes spot features of AI-generated text on your own. AI content tends to be more predictable and formulaic than human content and sometimes has a stiff or formal tone.

When you’re trying to detect AI writing, keep in mind that no approach is 100% reliable. QuillBot’s free AI Detector provides a detailed report that gives percentages for both AI-generated and AI-refined content, which can help you make more informed decisions.
How can I see if an essay is AI generated?: To see if an essay is AI generated, you can upload it or copy and paste it into an AI detector. QuillBot’s AI Detector analyzes essays and provides a report detailing how much of an essay is AI generated or AI refined.

You can also manually analyze an essay for signs of AI writing, like predictable word choice and sentence structure or tone that’s different from the author’s other writing.

When trying to detect AI writing, remember that no approach can offer 100% certainty. It can be helpful to use multiple forms of analysis as a basis for your decision making.
How do I check if a document is AI generated?: The simplest way to check if a document is AI generated is to upload it to an AI detector. These tools quickly analyze the text and determine whether it is more likely to have been generated by a human or AI.

You can also examine the document yourself for typical signs of AI writing, such as predictable sentences and word choice or a generic sound.

When you’re trying to detect AI writing, remember that no method has perfect accuracy. QuillBot’s free AI Content Detector offers a detailed report that differentiates between AI-generated and AI-refined text, which can help you understand more clearly how a document was created.
How do computer scientists make AI chatbots sound so human-like?: Computer scientists make AI chatbots sound human-like through various technologies, mainly natural language processing (NLP) and machine learning.

A chatbot is a computer program designed to simulate human conversation. AI chatbots can learn from their past experiences in order to continuously improve.

They can also vary the language they use, which leads to more human-like answers. For example, instead of always saying “I can help with that,” an AI chatbot could also say “I can tackle that” or “I can take a shot at that.”

Remember that not all AIs are chatbots. For example, QuillBot’s Grammar Checker is powered by AI, but it is not a chatbot.
What is a chatbot in education?: A chatbot in education is a conversational computer program that helps students, teachers, and staff with learning and administrative tasks.

A chatbot is any computer program, often powered by AI, that simulates human conversation.

In education, chatbots might offer personalized learning and extra support, help students practice a foreign language, assist in brainstorming and proofreading, and automate administrative and organizational tasks.

While not a chatbot, another type of technology used in education is an AI Detector, which helps teachers decide if student work was written by AI.
Are chatbots AI?: Some chatbots are AI, but not all. A chatbot is any computer program designed to simulate human conversation.

Some of these are powered by AI and can tackle various, complex tasks. Other chatbots are rule- or keyword-based and have a more limited range of capabilities.

Likewise, not all AI are chatbots. For example, QuillBot’s Humanizer is a type of AI, but it is not a chatbot, as you do not have a conversation with it.
