StoreWords vs MerchantWords: Which Should Amazon Sellers Choose in 2026?
Both tools serve Amazon sellers — but they solve different problems. Here's an honest breakdown so you pick the right one (or the right combination).
The short answer
MerchantWords is a keyword research data tool: it tells you what shoppers search for, search volumes, and which keywords competitors rank for. StoreWords is an AI content generator: it writes your listing titles, bullet points, descriptions, and backend search terms for you. If your bottleneck is writing the listing, StoreWords (free plan, Pro $9/mo) is the pick. If your bottleneck is validating keyword demand, that's MerchantWords' territory.

What MerchantWords does well
MerchantWords has been an Amazon seller staple for years because of its keyword database: estimated search volumes, seasonal trends, and tools like Reverse ASIN that reveal which keywords drive a competitor's sales. If you're choosing what to sell or which keywordsdeserve a place in your listing, that data is genuinely useful — and it's a job AI copywriting tools don't do.
What StoreWords does well
StoreWords turns your product details into finished, publish-ready copy: Amazon titles, benefit-led bullet points, descriptions, backend search terms, A+ content ideas, and listing FAQs — plus Shopify descriptions, Pinterest pin packages, and customer email replies in the same workspace. Every new account gets 14 days of Pro free (no credit card), then $9/mo or a free plan at 5 generations/day.
Which should you choose?
- Choose StoreWords if listings take you hours to write, you sell on Shopify too, or you want Pinterest and support content from one tool.
- Choose MerchantWords if you already write good copy and your real question is which keywords are worth targeting.
- Use both if budget allows: research keywords in MerchantWords, then feed the winners into StoreWords to generate the actual listing.
Frequently asked questions
Is MerchantWords better than StoreWords for Amazon sellers?
They solve different problems. MerchantWords is a keyword research data tool — it shows search volume and keyword intel for Amazon. StoreWords is an AI content generator — it writes your titles, bullet points, descriptions, and backend search terms. Many sellers use keyword data to inform the copy an AI tool writes.
Can StoreWords replace MerchantWords?
Not fully. StoreWords generates backend search terms and keyword-optimized listing copy, but it does not provide search-volume data or competitor keyword intel the way MerchantWords does. If your main need is writing listing copy (not researching keyword volume), StoreWords covers it at a lower price.
How much does MerchantWords cost vs StoreWords?
As of October 2026, MerchantWords paid plans start at $35/mo (Silver), with Gold at $79/mo and Platinum at $149/mo. StoreWords offers a free plan (5 generations/day), a 14-day free Pro trial, and Pro at $9/mo. Check each site for current pricing.
Does MerchantWords write Amazon listings with AI?
MerchantWords' core strength is keyword data, not AI copywriting. StoreWords is built specifically to generate listing titles, bullet points, product descriptions, A+ content ideas, and FAQs with AI.
Which tool should a new Amazon seller start with?
If your bottleneck is writing the listing itself, start with StoreWords' free plan — you can generate full listing copy today at no cost. If your bottleneck is deciding which keywords to target and validating demand, a keyword data tool like MerchantWords addresses that first.
