Sell store owners a tool that turns reviews into ads
A small AI tool that reads an online store's customer reviews and turns them into product benefit lists, ad copy, and FAQ answers. Store owners pay a monthly plan.
The hard part: standing out from the general AI writing tools store owners already use.
Who pays
Online store owners pay a monthly subscription to turn reviews they already have into marketing copy. One builder says their tool reached $1,240 in monthly recurring revenue 14 days after launch, which is their own claim. They did not share their price, so the plan price is up to you to test.
How to build it
Accept reviews as a paste or file
Let users paste reviews or upload a CSV exported from their store or a review app such as Judge.me. Keep it to this one input at first.
Write the review-to-copy prompts
Use Claude to pull out what customers praise and complain about, then turn those points into product benefits, a few short ad versions, and FAQ answers that use customers' own words.
Build the simple web app
Use Claude Code or Cursor to build a one-page app with sign-in and saved results in Supabase, hosted on Vercel.
Charge a monthly plan
Add Stripe Checkout with a free first run and a monthly plan for ongoing use.
Show before and after examples
Post real examples on X and in store-owner communities that show a pile of reviews next to the ad copy and FAQs it produced.
