Check AI product copy against the applicable source sentence by sentence. Compare the numbers and units, then inspect the measurement definition, configuration, conditions, exceptions and uncertainty. Record the changed meaning and the correction required. After revision, read the new text against the source again before asking the responsible person to confirm the business facts and approve any store action.

A fluent rewrite can keep a number while changing what it promises. Shopify's AI product-description guidance warns that AI can invent details and recommends checking specifications before publishing. Use the comparison below to review one source and one proposed rewrite.

Which source and version are you reviewing?

Name the product, configuration, source version and person who can confirm its applicability. Keep the source text beside the proposed output. If two sources disagree, resolve that conflict before treating either as the comparison baseline. Our product fact-sheet guide covers that earlier preparation task.

The following source and rewrite fragments are authored teaching examples. They are not supplier statements, a GRC product, captured AI output or customer results. The assumed input, S0, reads:

Nominal width: 120 mm, measured at reference face R. This note applies only to Model A with Insert I1. Tolerance is not supplied. Outdoor use is unconfirmed. Model B is outside this note's scope.

S0 is the fixed input for this exercise. The example supplies no real drawing, tolerance, suitability test or business approval. The reviewer is checking whether the rewrite preserves this assumed meaning, not establishing that the product facts are true.

How can the same number become a different claim?

Compare “nominal width: 120 mm” with “exact width: 120 mm.” The digits and unit match. The second phrase adds exactness that S0 does not provide. Keep the word nominal and leave the absent tolerance unresolved.

Units also need a meaning check. Converting 120 mm to 12 cm preserves the length arithmetically, but it does not establish which dimension was measured or whether the value applies to another configuration. A correct conversion cannot supply an absent measurement definition.

Now compare “only to Model A with Insert I1” with “fits Model A.” The shorter version loses the insert requirement. A reader could apply it to Model A with another insert, which the source has not assessed. In the figure, follow that expansion of scope while the number stays unchanged.

Scroll sideways to compare the complete source condition and proposed scope.

Fictional source S0 covers Model A with Insert I1 only. A proposed rewrite saying fits Model A appears to include another insert, I2, although it is unassessed. The same 120 mm does not support that broader configuration scope.
The additional configuration is unsupported in this exercise. The diagram does not establish actual compatibility.

What belongs in a source-to-rewrite comparison?

Put the source sentence, proposed wording, difference in meaning and required action in the same row. Add a source locator, rewrite version, reviewer and review outcome to the working record. A comment such as “check the facts” gives the writer too little information to repair a particular claim.

These six invented rewrite fragments each change S0 in a different way. Read them as review exercises, not wording to reuse in a product description.

Scroll inside the table to read all four columns. Row IDs repeat so you can reconnect each correction to its source.

Authored teaching examples / no real product statements
Source sentence Proposed rewrite fragment Difference in meaning Disposition / correction
C1 / Nominal width: 120 mm. C1 / Exact width: 120 mm. C1 / Digits and unit remain; nominal becomes an unsupported exactness claim. C1 / Return: keep nominal; no tolerance or exactness supplied.
C2 / Applies only to Model A with Insert I1. C2 / Fits Model A. C2 / The required insert disappears, broadening the stated configuration. C2 / Return: retain only and with Insert I1.
C3 / Measured at reference face R. C3 / Overall width. C3 / The measurement reference becomes a different definition. C3 / Return: retain reference face R; ask the owner before redefining it.
C4 / Tolerance is not supplied. C4 / Built to tight tolerances. C4 / Missing information becomes a quality claim. C4 / Remove the added claim; retain tolerance as unresolved.
C5 / Outdoor use is unconfirmed. C5 / Suitable for outdoor use. C5 / An unknown becomes an affirmative suitability claim. C5 / Remove suitability; keep unconfirmed and ask the owner if needed.
C6 / Model B is outside this note's scope. C6 / Not compatible with Model B. C6 / Unassessed scope becomes a negative compatibility conclusion. C6 / Return: preserve the scope limit without claiming incompatibility.

C1 retains the visible value but changes its certainty. C2 drops a configuration condition; C3 changes the measurement definition. C4 and C5 turn missing information into affirmative claims. C6 goes in the opposite direction: a model outside the note's scope becomes a claim of incompatibility. Every row needs a specific correction or a question for the source owner.

Which conditions and unknowns must survive the rewrite?

Look for the words and relationships that limit a statement: only, with, for this configuration, except and subject to confirmation. Equivalent wording can preserve the same condition. Deleting it, moving it away from the affected claim or applying it to a different model can change the meaning.

Preserve the kind of uncertainty too. “Outdoor use is unconfirmed” supports neither “suitable outdoors” nor “unsuitable outdoors.” “Model B is outside this note's scope” does not establish that Model B is incompatible. Ask the responsible person for evidence if the page needs either answer.

The product-material gap guide helps organize missing or conflicting inputs. Here, the input already declares its limits. The review checks whether those limits survived the output, including limits that make the sales wording less convenient.

How do you return a precise correction?

Identify the affected sentence, quote the applicable source and explain the change in meaning. State what the revision must preserve and what remains unknown. For C2, useful feedback is: “Restore the requirement for Insert I1 and keep the scope limited to Model A with that insert. S0 does not support a statement about every Model A configuration.”

One corrected teaching passage, R1, is:

For Model A with Insert I1 only, the nominal width is 120 mm, measured at reference face R. Tolerance has not been supplied, and outdoor use remains unconfirmed. This note does not cover Model B.

This passage changes the sentence order while retaining the assumed fields and limits. It still needs a comparison against S0; calling it corrected is not a business sign-off. If the source is unclear, return a confirmation question rather than replacing the gap with a likely answer.

What do you recheck after the next rewrite?

Read the whole revised passage against the same source, including sentences that were not named in the feedback. Confirm the value and unit, nominal wording, reference face, insert requirement and the two unresolved scope questions. A requested correction can be present while another qualification has disappeared elsewhere.

Record the source version, revised text version and outcome. In this exercise, the recheck can establish consistency with S0; actual product confirmation is still absent. Inspect the corresponding title, summary, image labels, captions, alt text and metadata within the agreed task scope. Google's guidance for generative AI content calls for manual accuracy review and includes metadata in that review. It does not promise a ranking result.

The figure follows the correction back to the unchanged input. Keep the source and business-confirmation states visible alongside the wording result.

Scroll sideways to follow the source, returned fragment and revised passage.

A fictional fixed source S0 retains nominal 120 mm, Model A with Insert I1 and unconfirmed outdoor use. Returned rewrite R0 loses conditions; revised passage R1 restores them and is compared with S0 again. Real business confirmation and approval of a store action remain separate.
Recheck the revised output, not only the feedback instruction. A wording match does not grant technical approval or permission to publish.

What does a completed copy check approve?

A copy check records whether the reviewed wording is consistent with a named source within a defined scope. The person responsible for the product still confirms the underlying facts, applicability and public use. Approval of a specific Shopify write is another decision, followed by checking the saved fields and presentation.

The current Opsy documentation describes B2B inquiry-store work using confirmed materials, approved content actions and readback. The comparison table here is a proposed human-review method. It does not establish an automatic semantic checker, an Opsy import format or unreviewed synchronization across a store.

If the business owner later confirms a different insert or application, record a new source version and reopen the affected comparison rows. Our product-fact change guide covers that separate source-change task across content references. Do not silently broaden the rewrite while leaving its old source record in place.

What should you bring to a workflow discussion?

Bring one applicable source, its confirmation owner, the original rewrite and the source-to-rewrite comparison. Include the revised passage, recheck outcome and any unanswered business questions. Use those materials to identify missing input, changed meaning or an unclear approval boundary.
