Fluent writing can contain unsupported product claims. The practical skill is to separate what the brief establishes from what a draft adds. This exercise uses an intentionally flawed sentence so you can practise that judgement without claiming a real AI product was tested.
Start with a small approved fact set
For the fictional HT-01 tote, the supplied facts are: cotton canvas, natural colour, a 38 × 42 cm body, two handles, an open top, an inside pocket and spot-clean care. There is no load rating, certification, fabric weight or waterproofing claim.
Teaching draft, deliberately written for this exercise: “Our certified eco-friendly, waterproof tote is made from premium 400 gsm canvas, carries 20 kg and lasts a lifetime.”
This is not a captured response from a named AI system. Do not cite it as a product benchmark or proof of any model's behaviour.
Create the claim ledger
| Draft claim | Evidence in supplied facts | Decision |
|---|---|---|
| Certified eco-friendly | No certification or environmental evidence | Remove |
| Waterproof | No water-resistance specification | Remove |
| 400 gsm | No fabric-weight specification | Remove |
| Carries 20 kg | No tested load rating | Remove |
| Lasts a lifetime | No durability evidence or guarantee | Remove |
| Cotton canvas; 38 × 42 cm | Explicitly supplied | Retain |
Download the claim-review sheet. Add a source reference for each retained factual claim. If two sources conflict, record the conflict and ask which approved specification governs the project.
A corrected version
This natural-colour cotton canvas tote has a 38 × 42 cm body, two handles and an inside pocket. The top is open. Spot clean as directed, and check the dimensions against what you plan to carry. The supplied facts do not include a load rating or water-resistance specification.
The revision supplies usable information without pretending to know the missing details. An alternative could omit the last sentence if the client agrees that those unspecified features are irrelevant to the listing. It still must not replace the unknowns with positive claims.
A prompt for a controlled practice attempt
Write one concise product description using only these facts: cotton canvas, natural colour, 38 × 42 cm body, two handles, open top, inside pocket, spot clean. Do not add certifications, load capacity, waterproofing, shipping promises or performance results. After the description, list facts you would ask the supplier to confirm.
If you run this prompt, record the tool, date, input, relevant output and your corrections where permitted. Recheck every statement even when the instructions appear clear. A well-written prompt does not replace verification.
Check the client's requirements before using a tool
Use fictional material for practice. Before submitting client files to any AI service, check the client's permission, the service's current data terms and any restrictions in the agreement. If AI assistance is prohibited or disclosure is required, follow that condition.
Keep your contribution specific: you compared claims with the brief, removed unsupported statements, resolved wording and checked the final file. Do not claim exclusive rights, original research or commercial results simply because a tool helped draft text.
Deliver the corrected copy and the decision record
For a practice portfolio, show the fact set, teaching draft, corrected copy and ledger. Label the origin of every component. A genuine later experiment should include its actual record rather than reusing this deliberately flawed sentence as if a model produced it.
The two portfolio examples show how this claim check fits into a finished writing deliverable. The content-plan exercise applies the same discipline to captions.
