How to Force AI to Write Accurate Product Descriptions Without “Hallucinations” and Inventions
The neural network beautifully detailed that “the kit includes a convenient plastic case and 3 batteries,” while in reality, this model sits in your warehouse in a cardboard box with just two batteries. AI simply took the “internet average” and made up what it didn’t know.
In the world of artificial intelligence, this is called a **hallucination**. For poems or social media posts, it’s perfectly fine, but for product specifications, it’s a direct path to returns and lost trust.
How do you domesticate a neural network in a chat and force it to stay strictly on point? Here are 4 golden rules of prompting for e-commerce.
Rule 1. Forbid the AI from “Thinking” (The Rigid Rails Method)
A neural network always tries to be helpful and fill in the blanks. If you don’t give it precise data, it will invent it. Therefore, the **main rule** is: never ask it to write a text by simply providing the product name.
«Write a description for the Samsung Galaxy A55 smartphone.»
Before asking for text, copy the raw specifications from your website’s admin panel or the supplier’s price list and hand them over to the AI along with strict instructions.
Correct Request Template:
«You are a professional e-commerce content manager. Your task is to write a product description strictly based on the specifications I provide.
STRICT RESTRICTION:** You are forbidden from inventing details, features, package contents, or numbers that are not in my list. If there is little data, keep it short, but do not make things up.
Here are the product specifications:
[Insert your copied list: brand, color, dimensions, power, etc.]»
Rule 2. Implement a “Safe Failure” Rule
Since content managers often process products in bulk, it’s easy to miss a micro-lie from the AI. Force the neural network to signal problems itself. To do this, introduce a special text marker (flag) into your prompt.
Add the following line to the end of your request:
Now, when scrolling through the finished text in the chat, you will instantly notice where the AI hesitated and can quickly fix that specific point manually.
Rule 3. Kill “Fluff” and Cliches at the Root
Hallucinations can be stylistic as well as digital (like mixing up voltage). AI loves to write things like: *“this revolutionary gadget will absolutely change your life”* or *“the perfect choice for everyone.”* In technical texts, this looks cheap.
Give the neural network a list of “stop words.”
«Write in a calm, informative style. Avoid empty cliches like: ‘unique’, ‘innovative’, ‘highest quality’, ‘absolute leader’. Instead, focus on the benefits derived from facts. If it says ‘5000 mAh battery’, translate it into a benefit: ‘the smartphone will last a full day of active use without recharging’.».
Rule 4. Use “Two-Step Verification” in the Same Chat
If the product is complex (expensive equipment, car parts, medical devices), do not copy the text to the site immediately. Take one extra step in the very same dialogue window.
«Now, strip away all the fluff, carefully re-read the text you just generated, and compare it with the raw specifications I gave you at the very beginning. Write a list for me: is there even a single fact, number, or promise in the text that was not present in the original data?»
You’ll be surprised, but at this stage, the AI often “blushes” and admits: *“Apologies, I stated that the warranty is 2 years, though this was not mentioned in the source data.”* It then immediately provides an updated, corrected version.
The Ultimate Master Prompt
Save this template for yourself. You can use it for any product:
Style and Safety Instructions:
1. Use ONLY the facts and numbers specified below. Do not invent anything.
2. Write for people: translate dry numbers into clear benefits (for example, if the weight is low, mention that it is comfortable to hold in hand).
3. No “fluff” or promotional cliches (remove words like: revolutionary, perfect, best).
4. Break the text into logical paragraphs and add a short list of key benefits (3-4 bullet points).
5. If there is too little information, write a short text, but do not make up product properties out of your head. If in doubt, add the marker [REVIEW] at the end.
Here is the source product data:
[INSERT NAME AND SPECIFICATIONS HERE]
Artificial intelligence is not a replacement for a content manager, but a super-efficient assistant. However, it needs to be treated like an intern: give it clear boundaries, forbid it from showing excessive imagination where dry numbers are needed, and always ask it to double-check its own work.
