For Shopify merchants
Know what’s being said in your name.
Shopify shares your listings with ChatGPT, Gemini, Copilot and Meta’s Muse as an AI-written summary you can’t see. Hearsay shows it to you next to your own copy and flags anything you didn’t say.

How it works
Contradictions first. Then claims you never made. Then products AI can’t find at all.
-
Enter your store
We pull the version of each product that Shopify’s catalog gives AI agents.
-
Compare it with yours
Your words on the left, theirs on the right. Anything you didn’t write is bracketed.
-
Fix yours, watch theirs
Install to check every product and get an email when the AI version changes.
We’re not kidding. We actually found these.
Our reviewers flagged every example below, then we checked each one by hand against the brand’s own page. We left the brands’ names out. The products are real.
14%
of 192 top-ranked products were described to AI agents with a claim that directly contradicts the brand, on health, safety or what’s in it. For baby products: 1 in 5.
89%
had at least one claim the brand never made.
70%
had one about health, safety, certification or what the product does.
The brand says
“Tallow from grass-fed cows, naturally-mined baking soda … and coconut oil”
AI agents were told
“Essential oil-free and [tallow-free] formula”
The brand says
“Ages 4+ can take 1 gummy per day … If not chewed properly, this product is a potential choking hazard.”
AI agents were told
“…multivitamin gummies [for kids ages 2 and up]”
The brand’s note removing dosing for ages 2–3 was sitting inside Shopify’s own record.
The brand says
Its FAQ says it “has not been tested for noncomedogenicity.”
AI agents were told
“Lightweight, [non-comedogenic], oil-free, and sulfate-free formula”
The brand says
“Sodium Benzoate: Food–grade preservative. Sodium Dehydroacetate: Organic salt preservative.”
AI agents were told
“Free from: synthetic fragrances … and [preservatives]”
The brand says
“meant for skin of all ages (under 6 months consult your pediatrician)”
AI agents were told
“[Pregnancy safe and suitable for use from birth]”
[also found]
Two [fragrance-free] products whose own ingredient lists include fragrance or essential oils.
How we checked: On Sep 24, 2026 we took the top 10 products Shopify’s catalog returned to AI agents for 20 everyday searches (192 products). AI reviewers checked all 3,546 claims against each brand’s own copy: description, tags and product page. Every example was verified by hand. “Serious” covers health, safety, certification and what a product does. This is one day and the top results only, and listings change. Full method

Fair questions
- Can Hearsay change what Shopify says?
- No. Nobody outside Shopify can edit its summary. We show you what it says, explain what’s off, and suggest changes to your own listing that may help.
- Which AI agents does this cover?
- We read Shopify’s catalog, which feeds agents like ChatGPT, Gemini, Copilot and Muse. Each agent may use that data a little differently.
- Do I need to install anything for the free scan?
- No. Type your store name and we check 5 of your products, and tell you how many of your products are in Shopify’s AI catalog. Installing checks every product, re-checks daily and emails you when something changes.
- Why only 5 products for free?
- Checking a product properly takes real work on our end. Five is enough to see whether Shopify’s summary matches what you wrote. Installing covers the rest.
- Will you tell anyone what you find?
- No. Your report is yours. When we share examples publicly, we never name the brand.
You didn’t say that.
