Correction or generation

The Boundary Isn't the Word AI. It's What the Tool Does.

A checker can use AI internally and still perform correction only. A generative tool creates ideas, structure or wording that was not present in the input.

The useful rule

Classify the action, not the brand

One product may fix a typo, rewrite a sentence or create a paragraph. Academic policies should name the allowed depth of intervention and any disclosure requirement.

VUST cannot decide compliance for your institution.

This is a classification framework, not a universal academic-integrity rule.

Three levels of intervention

One AI label can hide very different actions.

Spelling

Input

The student wrote: “Their conclusion are not supported by the data.”

Correction

“Their conclusion is not supported by the data.” The meaning and argument already belonged to the writer.

Rewriting

Input

Make my paragraph clearer without changing the facts.

Gray zone

The expression changes more substantially, but the source content already exists. Course policy decides whether it is allowed.

Generation

Input

Write an argument about the causes of the reform and add examples.

New content

The model creates structure, claims and wording the writer did not supply.
