Free tools · Working backends, not lead-bait PDFs

Nine free tools for product AI visibility.

Each tool answers one question an ecommerce team actually asks: are my products cited, can an agent read my PDPs, and what do I fix first. Results render in the browser; the top three findings are always free.

How the nine tools fit together

The graders measure, the generators fix, the calculator sizes the prize. The SKU Visibility Grader tells you whether your products are visible to AI engines today, store-wide. The AEO Grader scores a single page's answer-engine readiness so you can audit a hero PDP before a launch. The Agentic Readiness Grader covers the newest layer — whether your storefront is wired for agent-completed checkout via the Universal Commerce Protocol and the Agentic Commerce Protocol. The AI Crawler Simulator goes one level below all of them: it shows the raw plain-text view a non-JS crawler gets, with per-bot robots.txt verdicts for ten crawlers. The ChatGPT checker and the AI Overviews checker zoom all the way in: one product, one engine each — live GPT-4o prompts on the first, live structural checks plus a web-grounded Gemini probe on the second.

When a grader flags a gap, the generators close it. The llms.txt generator (following the llmstxt.org proposal) and the schema generator fix the two most common technical failures that cost ecommerce brands AI citations — a missing crawl map and thin Product JSON-LD. The ROI calculator turns the findings into a number a CFO will read.

Pick the right tool for the job

Quarterly readiness review: run the AEO Grader and the Agentic Readiness Grader, archive both scores, track movement.
Pre-launch check on a hero product: pair the schema generator with the ChatGPT checker.
Suspected robots.txt or rendering problem: the AI Crawler Simulator shows exactly which bots are blocked and what survives a no-JavaScript fetch.
New store onboarding: the SKU Grader first, then the llms.txt generator.
Board deck next week: the ROI calculator plus the prove-AI-search-ROI walkthrough.

None of these are magic. They do what a hands-on SEO lead would do manually — fetch, parse, score, prioritize — faster and consistently. The full eCommerce Insights product runs the same checks continuously against every SKU and sends a weekly digest of what changed.

Frequently asked questions

Do I need to sign up to use these tools?

No. Every tool runs without an account and shows results in the browser — a composite score, the breakdown, and the top three findings. The full report (every finding, per-PDP scores, the complete generated file) unlocks with an email address. No credit card, no password, no trial timer.

Which free tool should I run first?

Start with the Shopify SKU Visibility Grader if you run a Shopify store — it samples five PDPs and answers the question brands actually ask: are my products visible to AI engines today? On any other platform, start with the AEO Grader on your best-selling PDP, then use the generators to close the gaps it flags.

Are these tools real audits or marketing quizzes?

Real audits. The graders fetch the live page, parse the actual JSON-LD, read the real robots.txt, and check for llms.txt at the domain root. The ChatGPT checker runs live prompts through GPT-4o with web search. The generators read your storefront's public data and produce copy-ready output. Nothing is canned except the sample reports labeled illustrative.

Is there a free LLM visibility tool in this list?

Yes — that category name maps to three of the nine. An LLM visibility tool checks whether large language models can see and cite your pages: here, the AI Crawler Simulator shows what the LLM crawlers actually fetch, the AEO Grader scores readiness, and the ChatGPT Product Visibility Checker runs the live citation test. The difference from brand-level LLM visibility tools is resolution — every check here lands on a specific product page, not a brand rollup.

Can agencies use the free tools for client audits?

Yes, including in pitch decks and paid audits. Agencies running three or more brands usually outgrow one-off runs and move to the Agency & Enterprise plan, which adds multi-store dashboards and scheduled scans. The free tools stay useful for first-touch prospect conversations. See eCommerce Insights for agencies.

How do the free tools differ from the paid product?

The free tools answer one-off questions about one URL or one store sample. The paid product runs the same checks across every SKU on a schedule — weekly on Starter, daily on Growth — tracks citation movement across six AI engines, and ships title, schema, and metafield fixes as reviewable diffs. Plans start at $99 per month with a 14-day free trial.

Ready for the whole catalog, not one URL at a time?

eCommerce Insights runs every check on this page against every product in your store, on a schedule, across six AI engines.
