The list
The tools, one by one
1. Hatchloop — AI-visibility-first (our tool)
Shopify app + free tools Free plan · $12/mo Starter
Full disclosure: this is us, and we are the new entrant on this list — no long review history yet, unlike the incumbents below. What’s different is the starting point: every other Shopify app here began as an SEO app and added AI features later; Hatchloop is built around AI visibility from the start. The free web tools work today with no install: a 0–100 AI-visibility checker that reads your store the way AI crawlers do, and a free llms.txt generator — both no-signup. The Shopify app — AI product descriptions, one-click Product/FAQ schema, and llms.txt kept in sync automatically — is launching on the Shopify App Store, with a free plan and a $12/month Starter tier.
Honest caveat: if you want a tool thousands of merchants have already reviewed, pick one of the incumbents below and use our free checker to verify the results.
2. StoreSEO — best free llms.txt inside a full SEO suite
Shopify app Free (25 products) · from $14.99/mo
As of August 2026, StoreSEO holds a perfect 5.0 rating from 675 reviews and is one of the few established apps that includes its llms.txt generator on the free plan, alongside schema markup and an “AI Readiness Score.” The free tier covers 25 products with 200 AI credits; paid tiers scale by catalog size from $14.99/month (100 products) to $249.99/month (10,000 products, multilingual). Strength: a genuinely complete SEO suite with AI features included, and pricing that maps cleanly to store size. Consideration: stores with more than 25 products hit the free-plan wall quickly.
3. Tapita AI SEO Optimizer — most generous free plan
Shopify app Free · $9.99/mo Basic
Tapita is the proof that a newer app can out-execute incumbents: launched in 2023, it has earned 2,461 reviews at a 5.0 average as of August 2026, with 24/7 chat support even on the free plan. The free tier is unusually generous — unlimited on-page audit, essential JSON-LD, bulk AI metadata — and the $9.99/month Basic plan is the cheapest paid entry among the apps here. Its listing now leads with AEO and llms.txt for ChatGPT and Gemini. Strength: value and support quality. Consideration: AI-visibility features are one part of a broad SEO toolkit rather than the core focus.
4. Booster AI SEO + AEO Optimizer — the most-reviewed veteran
Shopify app Free · $39/mo Pro · $69/mo Premium
Running since 2016, Booster has the largest review base in the category — 5,261 reviews at 4.8 stars as of August 2026 — and recently added “AEO” to its name. The free plan is diagnosis-only (SEO score, broken-link detection); the paid tiers turn on autopilot fixes including structured data, llms.txt, and “AI search prep.” Strength: proven automation and fast, well-reviewed support. Consideration: the AI-visibility features that this page is about sit behind the $39/month paywall.
5. SearchPie — established suite, AEO on the top tier
Shopify app Free · $39/mo · AEO at $99/mo
SearchPie (2,345 reviews at 4.9 as of August 2026) is a solid all-rounder: schema, speed tooling, 404 handling, and daily monitoring emails, with a workable free plan. Its AEO optimization, however, is gated on the $99/month Enterprise tier — the most expensive way to get AI-visibility features among the Shopify apps on this list. Strength: breadth and 24/7 support. Consideration: if AEO is specifically what you came for, you pay top-tier prices for it here.
6. Otterly.ai — entry-level AI search monitoring
SaaS tracker From $29/mo
Switching categories: Otterly.ai doesn’t change your store — it tracks how often your brand appears in AI answers for prompts you define. The $29/month Lite plan covers 15 prompts; Standard ($189/month) and Premium ($489/month) add volume and API access, and some AI engines are paid add-ons on top. The company announced passing 10,000 users in September 2025. Strength: the proven low-cost entry into continuous AI-visibility monitoring. Consideration: it tells you where you stand but fixes nothing — and per-engine add-ons can stack up.
7. Peec AI — the fast-growing tracker for teams
SaaS tracker From €85/mo
Peec AI starts at €85/month (roughly $95) with a 7-day trial and no credit card, deliberately undercutting enterprise tools while including competitor benchmarking and multi-engine tracking. It is the category’s fastest riser — the company reported $10M ARR and 2,500+ paying teams in May 2026, sixteen months after launch. Strength: agency-grade tracking at mid-market pricing. Consideration: built for marketing teams and agencies; for a single Shopify store, €85/month of monitoring only makes sense once the store-side basics are already fixed.
8. Profound — the enterprise category leader
SaaS tracker ~$99/mo Starter (annual) · ~$399/mo Growth
Profound is the reference point for the whole category: it reached a $1B valuation in February 2026 and reportedly serves brands including Target, Walmart, and Samsung. Self-serve pricing starts around $99/month for ChatGPT-only tracking (billed yearly) and ~$399/month for the Growth tier adding Perplexity and Google AI Overviews; the full platform is demo-gated enterprise. Strength: the deepest citation analytics available. Consideration: clearly built and priced for large brands — overkill for most independent Shopify stores.
