Otterly.AI vs CatalogScan
Otterly is the most popular budget pick for tracking how often AI assistants mention your brand at the prompt level. CatalogScan is the free, Shopify-specific catalog scan that tells you which 18 AI-agent-readiness signals are missing or broken on your store. They sound similar; they’re not. This page makes the choice clear.
From $25/mo. Tracks how often your brand appears in ChatGPT and Perplexity responses across hundreds of prompt variations. Daily monitoring, sentiment data, prompt-level analytics. The cheapest credible alternative to Profound for ongoing AI visibility tracking.
Free scan + $49/mo Pro. Inspects your Shopify catalog against 18 AI-agent-readiness signals (GTINs, ProductGroup JSON-LD, metafields, sitemap, OG tags, robots.txt) and returns a 0-100 score with a fix list ranked by points-impact. Pro tier auto-applies the fixes.

How to decide
- Pick Otterly.AI if your job is daily prompt-level tracking of how AI assistants describe your brand, and you’re comfortable interpreting the data and applying fixes manually.
- Pick CatalogScan if you’re a Shopify merchant who wants to know — today, free — which catalog signals are missing on your PDPs and what to fix.
- Run both as a stack: scan with CatalogScan, fix the catalog (Pro $49/mo bulk-fixes the 13 of 18 signals that auto-fix safely), then turn on Otterly $25/mo to track the resulting mention-rate lift. Total $74/mo.
- Skip both if you’re not on Shopify and you don’t need brand monitoring. Neither tool fits your problem.
The deeper story
Cause vs. effect
Otterly tells you about the effect — how often you appear, how you’re described. CatalogScan tells you about the cause — whether the structured signals on your storefront are clean enough for AI shopping agents to consider your products. If your products lack GTINs or your robots.txt blocks GPTBot, no amount of effect-tracking will tell you the right fix.
Free up-front, paid for the auto-fix
CatalogScan’s economic model is "free scan as lead magnet, paid auto-fix as monetization." The free tier returns a fix list anyone can implement manually. Pro ($49/mo) buys back the time of doing it across hundreds of variants. Otterly’s economic model is "subscription monitoring with no fix output" — different value capture.
Specificity beats coverage at the early stage
Most Shopify merchants start the AI commerce shift in 2026 with "I don’t know if I’m visible." A specific 18-signal catalog audit answers that question with concrete actions. A generic prompt-monitoring tool tells you you’re not visible without telling you why. We think the catalog scan should come first; ongoing monitoring should come second, after fixes have shipped.
