Does your copy repeat stock AI phrases?
It flags pages containing multiple phrases from the engine's stock-copy list.
What Check Engine measures
The check runs for a supported prose language and reads indexable prose. Taxonomy archive URLs are excluded. A page matches when at least 2 distinct entries from the stored phrase list occur in its prose. Repeating the same entry does not create another distinct phrase. The list is a literal set of writing tells, not a model that determines how the text was produced. For example, repeating the same stock phrase still leaves only a single distinct match toward the required 2 phrase matches.
Each page supplies its own prose as input. It does not inspect an author's writing history or use a probability score from an AI detector.
How to read the result
Matching pages produce a medium-severity finding with the phrases that matched. Their presence does not establish that a machine wrote the page. Review quoted examples and context before rewriting a passage that may be discussing those phrases.
Why it matters
Stock wording can say little about the business behind a page. The useful editorial question is whether the affected passage gives the reader information, rather than whether it can be assigned to a particular authoring tool.
How to fix it
Read the marked passage aloud and replace empty claims with an account of what you actually do. Keep real examples, limits and sources close to the statements they support. If the phrase is an example under discussion, review that context before changing it. A phrase list should guide an edit, not decide authorship.

Common questions
How many stock phrases trigger the AI-sounding copy check?
A page must match 2 distinct entries or more from the phrase list. Repetition of a single entry cannot fill that count.
Does a stock-phrase match prove an AI wrote my page?
No. The check reports wording patterns with a medium-severity finding. It cannot determine who or what wrote the text.
Are taxonomy archives included in the stock-copy phrase test?
No. Taxonomy archive URLs are excluded from the prose sample. The test also requires a language it supports.
