ShelfGrader vs Peec AI: free store grade or monthly AI monitoring?
Peec AI is an affordable monthly platform that monitors your brand's visibility across AI engines. ShelfGrader gives store owners a free grade of whether AI assistants can read their store, with a paid fix. Here is who each is for.
Peec AI comes up a lot when store owners start comparing AI-visibility tools, usually because it is cheaper than the enterprise names. That part is true. But cheaper does not mean it does the same job as a free store grader, and it is worth being clear about the difference before you pay for a subscription you might not need yet.
Peec AI is a monitoring platform. ShelfGrader grades one store for free and sells you the fix if you want it done. One watches your visibility over time; the other tells you why an assistant skips your store today and closes the gap.
What Peec AI is
Peec AI tracks how your brand shows up across AI engines, week after week. It measures your share of voice against competitors and your citation rate across models like ChatGPT, Perplexity and Google AI Overviews, and it shows you how those numbers move. That ongoing record is the product. It is aimed at marketing teams, often mid-market B2B companies with a content team ready to act on the data.
It is priced for that. The figures here are reported ranges, so check Peec for current pricing: as of 2026 it is reported from around 89 euros (roughly $100) per month, with higher tiers near $240 and $500 per month, and some engines such as Claude and Gemini billed as add-ons on top. Among the monitors it sits at the affordable end, which is a fair reason to like it. It is still a monthly subscription to watch your visibility, not a tool that fixes a store.
What ShelfGrader is
ShelfGrader answers one question for a store owner: can an AI shopping assistant read and recommend my store right now, and if not, what do I fix first?
You paste a store URL. In about a minute, ShelfGrader reads the live page the way an assistant does, grades it out of 100, lists the fixes ranked by impact, and shows you the competitor an assistant would pick instead. The grade and that fix list are free. Having the fixes done is the paid part: a $20 one-time pack generates your Product schema and llms.txt to paste in, and a $99 per month managed plan keeps them correct as your prices and products change.
There is no ongoing tracking and no share-of-voice chart. ShelfGrader tells you whether your store is readable to AI assistants today and closes the gaps when you want them closed.

Choose Peec AI if
- You have a brand and a content team, and you want to monitor visibility over time.
- Share of voice against competitors across engines is a number you need to report.
- You are comparing affordable monitoring tools and want ongoing trends, not a one-off check.
Choose ShelfGrader if
- You run a store and want to check, for free, whether AI can read it.
- You want the specific fixes spelled out, then done for you cheaply.
- You are not ready to pay monthly to watch a chart; you want to stop getting skipped now.
You can use both
For a growing brand the two fit together. Use ShelfGrader to find and fix the page-level reasons an assistant skips your products, since a monitor will show you that you are losing without generating the schema to fix it. Then use Peec to track how your visibility trends over time. Fix first, then monitor.
The honest bottom line
Peec AI is a reasonable, affordable monitor, and if you want ongoing tracking it does that well. Most store owners reading this are not there yet. They need to know whether AI assistants can read their store, and they need the fix. Checking is free. Run the ShelfGrader scan, read your grade and your ranked fixes, and add a monitor later, once the basics are handled.
Frequently asked questions
Is ShelfGrader a Peec AI alternative?
They overlap less than the category label suggests. Peec AI is a monthly subscription that tracks your brand's share of voice and citation rate across AI engines over time, built for marketing teams. ShelfGrader grades a single store the way an AI shopping assistant reads it and tells you what to fix. If you want ongoing monitoring, Peec is the right type of tool. If you want to know whether ChatGPT can read and recommend your store right now, the ShelfGrader grade is free and you can pay to have the gaps fixed.
How much does Peec AI cost?
Treat these as reported figures and check Peec for the current number. As of 2026, Peec AI is reported from around 89 euros (roughly $100) per month for its entry plan, with higher tiers near $240 and $500 per month, and some engines such as Claude and Gemini billed as add-ons on top. It is one of the more affordable monitors. ShelfGrader's grade is free; having the fixes done costs $20 once for the DIY pack or $99 per month for the managed plan.
What does Peec AI do that ShelfGrader does not?
Peec AI tracks your visibility continuously: share of voice against competitors, citation rate across engines, and how those move week to week. That history is its whole point. ShelfGrader does not monitor over time. It grades whether your store is readable and recommendable to AI right now and hands you the ranked fixes.
What does ShelfGrader do that Peec AI does not?
ShelfGrader reads your live product page, checks the exact signals an assistant needs (Product schema, a machine-readable price, availability, ratings, llms.txt), grades it out of 100, and shows the competitor an assistant would pick instead, in about a minute and for free. On a paid plan it then generates the Product schema and llms.txt for you to paste in. Peec reports on your visibility; it does not write the fix.
I run one store. Which should I start with?
Start with the free ShelfGrader grade. It tells you, today and for nothing, whether AI assistants can read your store and what to fix. A monthly monitor like Peec earns its keep once you have a brand worth tracking across engines and a content team acting on the data. For a single store that just wants to stop getting skipped, that is usually more subscription than you need yet.
Can I use both?
Yes. Use ShelfGrader to find and fix the page-level reasons an assistant skips your products, then use Peec to watch how your visibility trends over time. Fix first, then monitor.
How many AI engines does Peec AI track?
As of 2026, Peec AI covers around six AI engines. ChatGPT, Perplexity and Google AI Overviews are typically included on the main plans, and others such as Claude, Gemini, DeepSeek and Grok are billed as paid add-ons on top. Check Peec for the current list, since these change. ShelfGrader does not track engines over time at all; it grades whether your store is readable to AI shopping assistants right now.
Does Peec AI work for a single Shopify store?
It can, but it is built for brands and marketing teams tracking share of voice, so for one Shopify store it is usually more tool than you need. If your goal is simply to find out whether ChatGPT, Perplexity or Gemini can read your store and to fix what they cannot, the free ShelfGrader grade is the more direct starting point.
Is Peec AI an optimization tool or just monitoring?
Peec AI is monitoring. It reports your visibility and citation trends across AI engines; it does not write the fix for you. That is the gap ShelfGrader fills: it tells you the specific signals an assistant cannot read on your store, and on a paid plan it generates the Product schema and llms.txt for you to paste in. Monitoring shows you that you are losing; the fix is what stops it.
