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.

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.

Is QuillBot AI Detector accurate?

While no AI detection tool is 100% accurate, QuillBot’s AI Detector demonstrates high accuracy in differentiating AI-generated and human-written text.

What sets it apart from other AI detectors is its ability to further distinguish between completely AI-generated text and text that has been refined with AI writing tools.
