An AI product description generator that knows marketplace rules
This AI product description generator writes a complete listing from your product details — a title, five bullet points, a description, a specifications table and search keywords — shaped for Amazon, Flipkart, Shopify, Meesho or your own shop. Write one product at a time, or a whole CSV.
Listings get rejected for breaking rules more often than for bad style, so every part is checked as you go: length against the marketplace preset, Amazon’s title characters and word-repeat rule, and this page’s own compliance list — unprovable superlatives, health claims, promotions, refund promises, environmental claims, contact details, emoji and other brands. Numbers that aren’t in your specifications are flagged too.
Everything runs in your browser, with its built-in AI or IBM’s open Granite 4.0 Nano model (downloaded only after you agree), or with seeded templates that use nothing but your own specifications.
How to write a product listing
- Choose the Marketplace and type the Product name, brand and category.
- Paste the Specifications as “Key: value” lines, then add the Main selling point, the audience and a few search phrases. Put competitors under Brands to keep out to have them flagged.
- Press Write listing with AI, or Template listing for an instant version built only from your specs.
- Read the notes on each part, press ↻ to rewrite one part, and use Copy as HTML for a paste-ready product page block.
- For many products, open Bulk: CSV in → CSV out, paste or open a CSV, run it and download the results.
AI Product Description Generator features
Five marketplace presets
Amazon, Flipkart, Shopify, Meesho and a generic shop, each with its own title, bullet and description targets and its own keyword part.
Amazon’s current title rules
75 characters from 27 July 2026, none of ! $ ? _ { } ^ ¬ ¦, no word more than twice, plus a 125-character Item highlights line.
Compliance checks
Superlatives (“best”, “#1”, “100% leak-proof”), medical claims, promotions, guarantees, eco claims, phone numbers and links, emoji, ALL CAPS and other brands or marketplaces are flagged.
Specs stay specs
The specifications table always comes from your input, even when the AI writes the rest, and any number the AI adds is compared with your specs.
Bulk CSV
Up to 200 products per run — AI per row on your device (Stop keeps finished rows) or instant templates — downloaded as CSV with a notes column.
Worked example: the sample bottle on Amazon
With the sample details (Kaveri Home insulated steel water bottle, six specifications), the Amazon preset and seed 1, the template listing starts like this:
- Title (70 of 75 characters): Kaveri Home Insulated Steel Water Bottle, 1 Litre, 304 Stainless Steel
- Item highlights (124 of 125): A leak-proof lid that opens with one hand; holds 1 litre; made of 304 stainless steel; keeps cold for 24 hours; weighs 420 g
- Bullets 1–2: “Leak-Proof Lid: A leak-proof lid that opens with one hand, handy for office-goers and students.” · “Capacity: Holds 1 litre.”
What the example shows
“Sage Green” would have pushed the title past 75 characters, so it was left out of the title and moved into the fifth bullet with the weight and the hot-drink time. Because templates only reuse your own numbers, none of the parts is flagged — an AI draft that promised “36 hours” would be. Under Shopify, the same details get an SEO title (“Insulated Steel Water Bottle – Kaveri Home”, 42 characters) and a 159-character meta description.

About the compliance checks
The rule list is a safety net, not legal advice. Advertising codes such as India’s ASCI Code and the US FTC’s rules expect claims to be backed by evidence, and marketplaces add their own category rules (supplements, cosmetics, electronics) that go beyond any list. Treat a red note as “prove it or remove it”. For non-product text, the AI Description Generator covers about pages and app listings; to name a new product, try the Brand Name Generator; to inspect a bulk results file, the CSV Viewer.
AI Product Description Generator FAQ
How long can an Amazon product title be?
From 27 July 2026, Amazon asks for titles of 75 characters or fewer, spaces included, in every category except media; longer titles are gradually replaced by Amazon’s AI suggestion. Extra detail can go in the 125-character Item highlights field.
Why does this AI product description generator flag “best”?
Words like “best”, “#1” or “100% leak-proof” are claims you would have to prove. Marketplaces and advertising codes expect evidence, so the page flags them; replace them with a fact (“keeps cold for 24 hours”).
Can I use it for Flipkart and Meesho?
Yes. Neither publishes one public character limit, so their presets use this page’s own targets, labelled as such. Your seller panel shows the exact fields and limits for your category.
How does the bulk CSV mode work?
Give a header row with at least a name column (brand, category, specs, audience, usp and keywords are optional). Each row becomes a listing — by AI one row at a time, or by templates instantly — and you download a CSV with a notes column for anything flagged.
Will the AI invent specifications?
It is told not to, but small models can. Every AI part is labelled “AI draft — check facts”, the specs table always comes from your input, and new numbers are flagged.
Do my product details leave my browser?
No. Listings and CSV files are processed on your device; only the open model’s files are downloaded, once, if you agree.
