See what AI assistants read in your store.

Sigourney publishes your Shopify or WooCommerce catalog as clean product data that ChatGPT, Perplexity, Claude and Copilot can read, then shows you each week which products they read, how many shoppers they sent you and what to fix. Free during the beta.

The AI shopping shift

Your products are missing from where customers now search.

Customers are asking ChatGPT, Gemini and Perplexity to find products. But most store catalogs aren't machine-readable, so AI assistants skip right over them. Sigourney turns your catalog into clean, structured data those assistants can actually read and cite — so you're in the running when competitors' stores already are.

Structured product data in the schemas Perplexity, ChatGPT and Gemini ingest natively.

Automatic sync keeps prices, stock and descriptions current — Shopify changes arrive within minutes, WooCommerce syncs daily.

Simple setup

From catalog to AI answer in four steps.

  1. 01

    Connect

    Connect Shopify in about a minute or WooCommerce in about two — after that, syncing is automatic.

  2. 02

    Index

    Sigourney formats your catalog as Schema.org JSON-LD on public pages and notifies search engines via IndexNow.

  3. 03

    Get read

    AI assistants can read and cite your products when shoppers ask about things like them.

  4. 04

    Sell

    Shoppers click from the AI answer straight to your store — they buy on your site, not ours.

Connecting your store

No developers. No theme edits.

Sigourney reads your catalog through the official platform APIs and never touches your storefront code.

Shopify

~1 minute

Install Sigourney from the Shopify App Store and approve access. Your products import automatically and re-sync automatically every night. Free during the beta.

View on the Shopify App Store →

WooCommerce

~2 minutes

In WordPress, open WooCommerce → Settings → Advanced → REST API, create a key with Read permission, and paste the Consumer Key and Secret into Sigourney. Read-only — Sigourney never writes to your store. No plugin, no theme edits.

Measure it

See which assistants send you shoppers.

When shoppers arrive from ChatGPT, Perplexity, Gemini, Copilot or Claude — and when they click through to your store — Sigourney counts it, by assistant, right in your dashboard.

  • Visits from AI assistants to your catalog, broken down by source
  • Click-throughs from your catalog to your own product pages
  • Links tagged with UTM parameters, so the same visits appear in your own analytics

We measure visits and clicks — the sale itself is recorded by your store, where it happens.

How much does Sigourney cost?
Sigourney is free during the beta: up to 3 stores and 500 products per store, no card needed. If paid plans ever come back, we will tell you well in advance; nothing is charged automatically. View plans →
Do I need a credit card to start?
No. Sign up, connect your Shopify or WooCommerce store and publish your catalog. No card and no trial clock.
What do I get each week?
A short email: how often AI search assistants read your products, how many shoppers they sent to your store, and the top fixes for your product data, with where to make each one.
What if I have more stores or products?
Write to hello@sigourney-saas.com and we will raise the limits for larger catalogs during the beta.
How does Sigourney decide which products to index?
Sigourney publishes all active products in your connected store, up to 500 per store during the beta. If a store has more, the oldest products are published first. You can hide individual products from your public catalog through the Sigourney connector in Claude.
What happens to my data?
Your product data is stored securely in our database to power AI search indexing, with access isolated per account — only your store sees your data. We never sell or share your data with third parties. For details, see our Privacy Policy.
Which AI assistants does Sigourney support?
Sigourney publishes your catalog as Schema.org JSON-LD on public pages that ChatGPT, Perplexity, Claude, Copilot and Google Search crawlers are allowed to read, and checks every product against what ChatGPT, Google Merchant Center and Shopify Catalog require before they show it. Each assistant decides on its own whether and when to show your products — no tool can guarantee placement.
