Does a grammar checker count as generative AI?

That depends on the feature and the course rule. VUST Grammar is configured to fix grammar, spelling, and punctuation rather than draft a new argument. An institution may still classify AI-assisted editing as an unauthorized resource, so the assignment policy takes priority.

Can a detector prove that AI wrote the paper?

No automated result establishes authorship by itself. Turnitin describes its score as one input for a conversation rather than a misconduct decision, and institutional guidance also calls for process and supporting evidence.

What should I keep before submission?

Keep the original text, version history, notes, sources, and, where required, a short disclosure of permitted assistance. Do not edit merely to manipulate a detector score.

Does VUST guarantee that a teacher will not notice?

No. VUST does not promise a third-party detector score or help conceal prohibited use. GrammarBot performs narrow correction on your text; your institution decides whether that use is permitted.

Corrected Text Does Not Prove AI Authorship

VUST Grammar corrects errors in your text rather than drafting a new argument. But the assignment policy decides whether the tool is allowed, and an automated flag does not replace reviewing drafts, version history, and your ability to explain the work.

Review the feature, the policy, and the process, not one percentage

VUST gives GrammarBot a narrow job: fix grammar, spelling, and punctuation, preserve meaning, and avoid explanations or new content. Turnitin recommends treating an AI score as one conversation input, while Penn State and Harvard separately emphasize detector limits and the value of drafts and version history.

This is not legal advice or a promise about a specific institution's decision.

Correction, generation, and evidence are different things

Action	What changes	What to verify
Spelling and punctuation	The form of your source text	Whether editing is allowed
Grammar correction	Incorrect forms and agreement	Whether meaning and voice remain
Paragraph rewrite	Wording and sometimes structure	Whether AI assistance must be disclosed
Detector score	A probabilistic signal, not authorship	Drafts and supporting evidence

If the work is flagged

1. Check the assignment rule: Some courses allow spelling and grammar assistance; others prohibit any AI-enabled tool. There is no universal institution rule.
2. Keep process evidence: Retain the original draft, version history, and narrow correction output. These show how the work developed better than an argument about a detector percentage.
3. Separate correction from generation: Fixing a typo or agreement error is not the same act as generating an argument, example, or paragraph. A content rewrite is a different level of assistance.
4. Request human review: If the work is flagged, explain the process calmly, show drafts, and ask for the total evidence to be reviewed under the institution's policy.

Reviewed basis: Turnitin, Penn State, and Harvard Bok Center.

Based on: What GrammarBot actually does, plus institutional guidance, with no detector-accuracy claim.
Best for: Students and ESL writers using narrow correction where it is permitted.
Not ideal for: Concealing prohibited generation or manipulating a detector score.
In short: Drafts and the assignment rule matter more than one automated flag.
