The report card
Best for llms.txt and AI search checks on Shopify
IndexGPT scores how ready a Shopify store is for AI search, lists fixes, submits pages through IndexNow and builds llms.txt and Agents.md files. Prompt and sentiment tracking, the schema builder and AI blog writing need Premium at $45 a month, the trial lasts 3 days, and credit limits below Enterprise aren't stated.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Essentials is $16 every 30 days, above this category's $10.99 middle. Prompt tracking, the schema builder and AI writing, the parts its name points to, need Premium at $45, in the dearest tenth; Enterprise is $345. |
| Free plan and trial | D | No free plan, and the free trial is 3 days, shorter than a week. After that, the cheapest plan is $16 every 30 days. |
| Features | C | An AI readiness score with fixes, IndexNow, llms.txt, Agents.md and robots.txt checks, and on Premium prompt and sentiment tracking, a schema builder and AI posts. It covers AI search, with no meta tag, sitemap or redirect editing listed. |
| Ease of use | C | No rating on record. It installs from the Shopify App Store, but the action plan is a list of fixes to work through, and tracking means choosing prompts. |
| Platforms and integrations | B | Web, inside the Shopify admin, linked to Google Analytics and IndexNow, with ChatGPT, Gemini and Claude named for visibility tracking. No phone or desktop app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of IndexGPT: AI SEO for ChatGPT you could make: schema markup and long-form writing. What surrounds it you could not. The 4 things listed below take a company, not a weekend.

What you could make
- Schema markup and long-form writing: an app builder makes these well.
What you could not
- The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept.
- A crawler that checks every page of a site.
- It plugs into other products, Shopify, Google Analytics and IndexNow among them.
- AI features, unless you pay a model provider for each request yourself.
