An Otterly.AI alternative for Shopify stores
Otterly.AI starts at $25/mo and is the most popular budget pick for tracking how often ChatGPT and Perplexity mention your brand. CatalogScan is free, scans your actual Shopify catalog against 18 AI-agent-readiness signals, and returns a prioritized fix list. They’re aimed at different problems — this page makes it clear which one you’re actually facing.
Choose Otterly.AI if
You want low-cost, ongoing prompt-level tracking of how AI assistants describe your brand. You’re happy to interpret the data yourself and apply the fixes manually. You’re not necessarily on Shopify.
Choose CatalogScan if
You run a Shopify store and you want to know — free, in 2 minutes — exactly which catalog signals are missing or broken on your product pages, with a fix list ranked by points-impact and a Pro tier ($49/mo) that auto-applies the fixes via Shopify OAuth.

The real difference: which side of the funnel?
Otterly tells you what AI assistants are saying about your brand right now. CatalogScan tells you whether AI shopping agents can read your catalog at all. If your products lack GTINs, your PDPs lack ProductGroup JSON-LD, or your robots.txt is blocking GPTBot, the agent never gets to a recommendation in the first place — and Otterly’s "low mention rate" alert can’t tell you that. CatalogScan can.
A reasonable progression for a Shopify store starting today: run a CatalogScan free scan, ship the top-5 fixes (or upgrade to Pro and have the bulk-fix do it), then turn on Otterly to track the resulting mention-rate lift. That sequence puts the cause-fix loop ahead of the measurement loop, which is the right order for catalog-side work.
Pricing math for a Shopify merchant
A small Shopify brand on Otterly’s entry tier is $300/yr for prompt monitoring with no fix recommendations. CatalogScan free returns a fix list the same day — same year, $300 saved, plus the actual catalog gets cleaned up. If you do want both signals (Otterly’s prompt monitoring and CatalogScan’s catalog audit), Otterly $25/mo + CatalogScan free is still cheaper than most single-vendor enterprise alternatives.
When Otterly.AI is still the right call
If your priority is daily prompt-level tracking of how AI assistants describe you (sentiment, comparison framing, attribute callouts) across hundreds of query variations, Otterly does that natively and we don’t. If you’re not on Shopify at all, CatalogScan is irrelevant — Otterly will be a better fit. We genuinely don’t replace Otterly for the brand-monitoring job; we replace it (well, the spend) for the "what do I actually fix?" job.
