Free Product Description Generator

What is a product description generator?

A product description generator is a free tool that turns your product name and key features into a polished, ready-to-publish description in seconds. Enter the product, its features, and who it’s for, pick a tone, and this free product description generator writes a hook, a benefit-led paragraph, feature highlights, and a closing call to action.

It works as a product copywriter for Shopify, Amazon, Etsy, and your own store, helping you turn dry spec lists into copy that sells — without staring at an empty product page. Paste it in, tweak the details, and publish.

When you have a whole catalogue to write — SEO-aware, on-brand descriptions at scale — the Product Description Writer Skill (Anna) on KissMySkills turns Claude, ChatGPT, or any AI chat into a dedicated product copywriter.

The copy that sells on your page gets your feed rejected

Product copy has two audiences with opposite preferences: shoppers reading your page, and the shopping feed that ingests the same text.

Google’s Merchant Center specification accepts 1–5,000 characters in the description attribute and 1–150 in the title, truncating longer titles to fit. What it will not accept is most of what makes good marketing copy. Promotional text is prohibited outright — price, sale price, sale dates, shipping and delivery information, even your own company name. So are links to your store, comparisons with other products, and details about accessories rather than the item itself.

Formatting is constrained too. Capital letters for emphasis are disallowed, with Google noting plainly that capitalised text is common in spam and untrustworthy ads, and the same applies to symbols and other gimmicky attention-drawing devices.

Which means a description opening “SAVE 40% THIS WEEK ONLY” is a perfectly reasonable line on your own product page and a disapproved feed item. Write the page copy for shoppers and keep a clean, descriptive version for the feed. (Merchant Center attribute rules are revised regularly — check the current specification before you build a template around these numbers.)

When a description stops being marketing and becomes a regulated claim

Some phrases carry legal obligations that arrive with the words themselves, and US rules explicitly reach material distributed electronically — a product page is not exempt because it is not a printed catalogue.

“Made in USA.” The FTC rule requires final assembly or processing in the United States, all significant processing in the United States, and all or virtually all ingredients or components made and sourced there. It covers “made,” “manufactured,” “built,” “produced,” “created,” “crafted,” and any other unqualified US-origin claim.

“Organic.” The USDA thresholds are exact: 100% organic means every ingredient; plain “organic” requires not less than 95%; “made with organic ingredients” requires at least 70%. Below 70% you cannot call the product organic at all.

Supplements. A structure/function claim must carry the disclaimer verbatim — “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease” — on each page where the claim appears. Cross into a disease claim and the product is regulated as a drug.

Textiles. Naming a fibre or fibre trademark in advertising triggers full fibre-content disclosure in at least one place in that advertisement, and these rules expressly cover the internet. Online catalogue copy must also state clearly whether the product was made in the USA, imported, or both.

Reviews and testimonials inside product copy

Since October 2024 a dedicated FTC rule has governed consumer reviews and testimonials, and it is unusually direct about generated text: the Commission stated that AI-generated reviews are covered by the final rule.

The rule prohibits writing, creating, buying or selling reviews that misrepresent that the reviewer exists, that they used the product, or what their experience was. It also bans compensation conditioned on a particular sentiment — positive or negative — undisclosed reviews by employees, officers or their immediate relatives, company-controlled sites presented as independent, and suppressing negative reviews while implying the displayed ones represent all of them.

The older Endorsement Guides still apply alongside it. A material connection that the audience would not reasonably expect must be disclosed, and free or discounted product counts as a material connection regardless of whether you asked for a review in return. An advertiser is liable for a deceptive endorsement even where the endorser is not.

Two details are easy to miss. Consumer endorsements are explicitly not competent and reliable scientific evidence, so quoting a happy customer does not substantiate a performance claim. And on the web a disclosure is not clear and conspicuous if the reader has to take any action to see it — clicking a link or hovering over an icon does not count.

What this generator can’t do

It can’t know whether your claims are true. This is the whole risk. A generator writes “ethically sourced,” “hypoallergenic,” “100% cotton” or “made in USA” because those phrases fit the pattern, not because it checked. You need substantiation before publishing, and you are liable for the claim regardless of what wrote it.

It can’t supply the facts only you hold. Fibre percentages, country of processing, certification status, organic percentage by weight. Each is a required disclosure in its context and none can be inferred from a product name.

It can’t write differently for every channel. One description cannot simultaneously satisfy your product page, a shopping feed that bans promotional language, and marketplace rules that vary by category.

It can’t keep a catalogue distinct. Fed similar inputs it produces similar outputs, which is how stores end up with two hundred descriptions sharing a structure and half their sentences. Vary the inputs, not just the tone setting.

Use it to escape the blank page and to get a consistent structure across a catalogue. Then check every factual claim, every regulated word, and every number against what you actually know about the product.
