Prompt: check that your English and French versions say the same thing
Give an AI both versions of an offer and get a table of every mismatch in numbers, eligibility, deadlines and exceptions, with the question you need to answer for each one.
Works with: ChatGPT, Claude, Copilot, Gemini
The task
Find the facts that differ between the English and French versions of the same offer, notice or policy, before a customer finds them.
Compare these synthetic English and French statements for factual equivalence. Report mismatches in numbers, eligibility, deadlines, exceptions and promises. Do not rewrite either statement. Return a table: English fact, French fact, mismatch, question for the owner. EN: Free delivery on orders of CAD 150 or more, before tax, excluding remote areas. FR: Livraison gratuite pour les commandes de plus de 150 $ CA, taxes comprises.
How to use it
- Run it once with the synthetic example above to see the kind of table you get.
- Replace the EN and FR lines with your own two versions (an offer, a return policy, a job posting).
- Answer every question in the last column, then fix BOTH versions so they say what you decided.
What you get
A table with one row per fact. Each mismatch is named (number, eligibility, exception, promise) with a question you can answer, and nothing is rewritten for you.
| # | English fact | French fact | Mismatch | Question for the owner | |---|---|---|---|---| | 1 | The offer is "free delivery" | The offer is "livraison gratuite" | None. Both say the same thing. | None | | 2 | The amount is CAD 150 | The amount is 150 $ CA | None. Same amount, same currency. | None | | 3 | "150 or more": an order of exactly $150.00 qualifies | "de plus de 150" means more than 150: an order of exactly $150.00 does not qualify | Yes, on eligibility. The two versions treat an order of exactly $150.00 differently. | Should an order of exactly $150.00 get free delivery? | | 4 | "before tax": the threshold uses the subtotal | "taxes comprises": the threshold uses the total including tax | Yes, on the number. The French threshold is lower in practice. For example, a $135 subtotal plus Quebec sales tax comes to about $155.22. That qualifies in French but not in English. | Is the $150 measured before tax or after tax? | | 5 | "excluding remote areas": some places are left out | No exclusion | Yes, on the exception and the promise. The French version promises free delivery everywhere. | Should the remote-area exclusion also apply to French-speaking customers? Which areas count as "remote" (a list of regions or postal codes)? | | 6 | No deadline or end date is stated | No deadline or end date is stated | None. Both versions are silent. | Does the offer run indefinitely, or does it end on a set date? | Overall: the French version gives customers more on two points (rows 4 and 5) and less on one (row 3). […] Align both versions before publishing.
