Perplexity measures how predictable the words in a piece of writing are, while burstiness reflects how predictable its structure is.
Because human writing often scores higher for these measures than AI-generated text, it may seem like maximizing them is always better. However, in many cases, lower perplexity and burstiness can make a text easier to read and understand.
If word choice is predictable (perplexity), text becomes easier to read. Likewise, if the structure is predictable, it may be easier to skim.
In fact, even poor writing (like spelling errors or run-on sentences) can inflate burstiness and perplexity.
For these reasons, the ideal balance depends on the context and purpose of writing. Still, these measures help tools like QuillBot’s AI detector determine whether something was written by a human or by AI.

Burstiness and perplexity are two metrics that capture patterns in a piece of writing. Perplexity measures how easy it is to predict which words come next, and burstiness measures how easy it is to predict sentence structure and length.
These measures are used by tools like QuillBot’s AI detector to guess whether something was written by a person or an AI. They can also be used to evaluate the quality of an AI text generator.

Perplexity measures how predictable the words in a sentence are.
Consider the phrase: “I sat at the bar and ordered a glass of red…” A low-perplexity (i.e., highly predictable) ending would be “wine.” Conversely, a high-perplexity (less predictable) ending might be “jelly beans.”
AI-generated text often has lower perplexity than human writing. Perplexity is therefore used by tools like QuillBot’s AI detector to guess whether something was written by a person or an AI.

Burstiness is a metric that captures how varied the structure of a piece of writing is. Elements like sentence length, sentence structure, and changes in word use impact burstiness.
An example of writing with low burstiness is as follows: “I have a dog. My dog’s name is Tim. Tim looks a bit scruffy. Tim’s ears stick out. Tim likes to go for walks.”
Compare this with an example of writing with high burstiness: “I have a dog. His name is Tim, and he’s a scruffy little character with ears that stick out sideways like broken antennae. Tim lives for walks—whether it’s a quick trot around the block or a long ramble through the park.”
AI-generated text often has lower burstiness than human writing. Burstiness is therefore used by tools like QuillBot’s AI detector to guess whether something was written by a person or an AI.

It is a tool, often AI-powered, that helps users quickly create professional, clear, and detailed scope of work documents by inputting project details.
The generator structures objectives, deliverables, timelines, and responsibilities into a well-organized draft that can be refined to fit your project’s specific needs. For a fast and reliable option, try QuillBot’s AI scope of work generator.
Read this FAQ: What is a scope of work generator?
A scope of work (SOW) should include the following:
- Project overview and objectives
- Detailed deliverables
- Timeline with milestones
- Roles and responsibilities
- Budget and payment terms
- Success criteria
Tools like QuillBot’s AI SOW generator can help structure these elements quickly.

A product review should be long enough to give meaningful details but concise enough to keep readers engaged—typically 150–300 words for online posts. With QuillBot’s product review generator, you can quickly produce a review of any length while keeping it informative and readable.
Read this FAQ: How long should a product review be?
Yes. Including both the positives and negatives makes your review balanced and trustworthy. Readers can make informed decisions when they see the full picture. Using an AI tool like QuillBot’s product review generator can help you structure both pros and cons efficiently.
Read this FAQ: Should product reviews cover both pros and cons?
An AI product review generator is a tool that helps you quickly create detailed, natural-sounding product reviews. You provide information about the product, and the AI drafts a review that you can edit and personalize. Tools like QuillBot’s free AI product review generator make this process fast and easy.

A press release template helps you to draft a press release and make sure you don’t forget anything. Press releases can be scheduled events, or they can be issued in times of crisis. This makes it especially important to get them right.
As well as a template, you can use an AI tool like QuillBot’s AI press release generator. This lets you input all the details you need, and it quickly produces a press release that you can check, fine-tune, and even redraft if you want to.
