Best AI Plugins for Generating WooCommerce Product Descriptions (2026)
The problem AI actually solves here is not that writing product descriptions is boring. It is that most stores are publishing the manufacturer’s supplied copy, which every other retailer selling the same item is also publishing, on pages Google has no reason to rank above anyone else’s. A catalogue of 2,000 products with identical descriptions to fifty competitors is not a writing problem, it is a duplicate content problem, and it is why bulk generation is worth doing at all.
Which makes the economics matter, because 2,000 products at 150 words each is 300,000 words. On one popular plugin’s entry plan that is roughly six months of your monthly allowance. With your own API key it is a single afternoon and a few dollars. This article prices catalogue-scale generation properly, then covers the part that determines whether any of it helps: making the output different enough to be worth indexing.
Pricing verified August 2026. Word allowances and credit definitions differ by vendor, so check what counts before choosing a tier.
What a catalogue actually costs to write
Assume 150 words per description, which is a sensible length for an ecommerce product page. Here is what different catalogue sizes consume.
| Catalogue | Words needed | Bertha free, 2,500/mo | Bertha ~$12/mo, 50,000/mo | Bring your own key |
|---|---|---|---|---|
| 50 products | 7,500 | 3 months | Same day | Same day, cents |
| 300 products | 45,000 | 18 months | Same day | Same day, cents |
| 2,000 products | 300,000 | Not viable | 6 months | Same day, a few dollars |
The pattern is the same one that shows up across AI tooling: metered plans are fine for a trickle and hopeless for a bulk run. A store adding four products a week will never notice a word allowance. A store migrating a 2,000-item catalogue hits the ceiling immediately, and the fix is not a bigger plan, it is a different billing model.
There is one genuine argument for metered plans, which is that they cap your spend. An API key with no limit and a badly configured bulk job can generate a bill you did not intend. If that risk worries you, set a spend limit in your provider’s console rather than paying a vendor several times the underlying rate to impose one for you.
The 5 tools compared
Five rather than a padded ten. The tools that genuinely generate WooCommerce product descriptions at scale are a small group, and most of the plugins listed elsewhere are general writing assistants with a product template attached.
1. AI Puffer, formerly AI Power
The best fit for catalogue-scale work, because it combines bring-your-own-key billing with genuine bulk workflows and native WooCommerce integration. That combination is what this job needs: no word ceiling, no per-description markup, and a way to process a product list rather than clicking through 2,000 pages individually.
Pricing is $9 a month, $79 a year, or $149 lifetime, with no hidden credits charged by the plugin; you connect your own provider account and pay them directly. For a store rewriting a large catalogue once and then adding products steadily, $149 once is close to the cheapest possible answer, and the lifetime licence removes the renewal question entirely. Note the rename from AI Power, which makes older reviews confusing to match against the current product. The breadth of the plugin, covering content, images, chatbots, and forms, means a busier interface than a single-purpose tool.
- Pricing: $9 a month, $79 a year, or $149 lifetime, plus your own API usage
- Model: Bring your own key, with bulk workflows
- Best for: Rewriting a large catalogue without a word ceiling
- Watch out for: Broad feature set; busier admin than a focused tool
2. Bertha AI
The most purpose-built option for this specific task, able to generate a WooCommerce product description from the product name alone, with deep Gutenberg integration and no external dashboard to manage. It also handles bulk alternative text generation, which matters more than it sounds on an image-heavy catalogue where alt text is usually missing entirely.
Pricing is metered by words. The free tier gives 2,500 words a month, paid plans start around $12 a month for 50,000 words, and agency plans with multi-site support start near $49 a month, with some sources listing around $20 a month for individual sites. Support for 25 languages is a genuine advantage for stores selling internationally. The limitation is structural rather than a flaw: a word meter suits ongoing publishing and does not suit a one-off bulk run, so use Bertha for a store adding products steadily and something unmetered for a migration.
- Pricing: Free 2,500 words a month; paid from around $12 a month for 50,000; agency from about $49
- Model: Bundled words, no separate API billing
- Best for: Stores adding products steadily, and multilingual catalogues
- Watch out for: Word meter makes bulk migrations impractical
3. AI Engine by Meow Apps
The cheapest capable route and the most future-proof, because it is explicitly a layer over whichever provider you choose rather than a reseller of one. It supports OpenAI, Anthropic, Google Gemini, Mistral, Perplexity, and OpenRouter, so when a model is retired or a cheaper one appears you change a setting rather than waiting for a plugin update.
There is a capable free version and Pro is $79. For product descriptions specifically it is less turnkey than Bertha, since you are writing the prompt template rather than picking a product description preset, and its WooCommerce bulk handling is less developed than AI Puffer’s. What you get in exchange is the lowest possible per-description cost and complete provider independence. For a store with a few hundred products and someone willing to write a good prompt once, this is excellent value.
- Pricing: Free version; Pro $79, plus your own API usage
- Model: Bring your own key, multi-provider
- Best for: Lowest cost per description with provider independence
- Watch out for: You write the prompt template; lighter bulk tooling
4. GetGenie AI
The option for a store owner who wants one subscription covering writing, SEO, and keyword research rather than assembling tools. Pricing starts around $9 a month or $72 a year, with a flat rate covering word generation and image credits and no separate provider billing to think about.
The keyword research bundled alongside generation is the genuine differentiator for product pages, because a description written around a term people actually search beats a fluent one written around nothing. Where it struggles is the same place every metered plan struggles: monthly word limits make a catalogue migration impractical, and heavy months hit a ceiling. Note too that image generation requires an annual subscription, which catches people who sign up monthly to test. Against AI Engine at $79 once, GetGenie at $72 every year is more expensive within about fourteen months.
- Pricing: From about $9 a month or $72 a year
- Model: Bundled credits, capped monthly
- Best for: One subscription covering writing, SEO, and keywords
- Watch out for: Monthly caps; images need an annual plan
5. Rank Math Content AI
Worth knowing about if you are already choosing an SEO plugin, because Content AI arrives inside a full SEO suite rather than as a separate subscription. Rank Math PRO is €95.88 a year covering unlimited personal sites, with Business at €299.88 for 100 client sites and Agency at €659.88 for 500.
Its advantage for product pages is that generation and optimisation live in the same tool, so the description is written against the keyword analysis rather than in a separate window. Content AI is offered as a trial allowance by tier with usage sold on top, so treat it as an assistant for individual products rather than a bulk catalogue engine. If you were buying Rank Math anyway, the writing help is close to free; if you are buying it specifically to generate 2,000 descriptions, choose something unmetered instead.
- Pricing: PRO €95.88, Business €299.88, Agency €659.88 a year
- Model: Content AI allowance by tier, usage sold on top
- Best for: Sites already buying an SEO suite
- Watch out for: Not a bulk catalogue tool

Making the output worth indexing
Generating 2,000 descriptions from the same prompt produces 2,000 pages that are different from your competitors and nearly identical to each other, which trades one duplicate content problem for another. The fix is in how you prompt, not in which tool you buy.
- Feed the attributes, not just the name. Pass size, material, colour, compatibility, and specifications into the prompt. A description generated from real attributes is genuinely specific; one generated from a product name is confident invention.
- Vary the structure deliberately. Write three or four prompt templates with different openings and orderings, and rotate them across the catalogue. Identical structure across every page is the pattern that looks automated.
- Never let it invent specifications. A model given a name and no data will confidently state dimensions and materials that are wrong, and in some product categories that is a consumer protection problem rather than an SEO one.
- Review the highest-traffic products by hand. Your top fifty products earn most of your revenue. Machine-generate everything, then edit those fifty properly.
- Keep it short enough to read. Around 100 to 200 words for most products. Length for its own sake helps nothing and buries the specification people came for.
- Publish in batches and watch. Push a few hundred, check indexing and rankings for a fortnight, then continue. Dumping 2,000 new pages at once gives you no way to tell what worked.

Frequently asked questions
Will Google penalise AI-written product descriptions?
Not for being AI-written. Google’s guidance targets low-value content regardless of how it was produced, and an accurate, specific description written from real attributes is not that. Near-identical descriptions across your own catalogue are a genuine risk, and so is manufacturer copy duplicated across fifty retailers, which is the problem you started with.
How long should a product description be?
Roughly 100 to 200 words for most products, with the specification presented separately as structured attributes rather than buried in prose. Buyers scan; they do not read four paragraphs about a phone case.
Should I replace manufacturer descriptions?
Yes, that is the main reason to do this. Manufacturer copy is identical on every retailer selling the item, so nothing distinguishes your page. Rewriting is the single clearest SEO gain available to a store carrying other people’s products.
Can AI invent product details?
Readily, if you give it a name and nothing else. It will state dimensions, materials, and compatibility that sound plausible and are wrong. Always pass real attributes into the prompt, and spot-check output in any category where an inaccurate claim has consequences.
Do I need a separate tool for meta descriptions?
Not usually. Most of these generate meta descriptions alongside the body copy, and several SEO plugins now generate metadata automatically on publish. Generate both in one pass rather than running the catalogue twice.
What about multilingual catalogues?
Generate natively in each language rather than writing in English and machine translating, since output written directly in the target language reads better. Bertha’s support for 25 languages is useful here, as is any bring-your-own-key tool pointed at a capable multilingual model.
The verdict
For a catalogue of any real size: AI Puffer at $149 lifetime, with your own API key. Bulk workflows, native WooCommerce integration, no word ceiling, and no renewal. A 2,000-product rewrite becomes an afternoon and a few dollars rather than six months of allowance.
For a store adding products steadily: Bertha AI, starting free at 2,500 words a month and around $12 for 50,000. Purpose-built for WooCommerce descriptions, good Gutenberg integration, and 25 languages if you sell internationally.
For the lowest cost per description: AI Engine Pro at $79, pointed at whichever model is cheapest this quarter. You write the prompt template once, and you are never stranded when a provider retires a model.
If you are buying an SEO plugin anyway: Rank Math PRO at €95.88, and use Content AI for individual products rather than the whole catalogue.
Whichever you choose, feed it real product attributes. The tool that generates from a product name alone is not saving you writing time, it is generating claims you will have to check anyway.
