A free scan and a paid monitoring subscription
Otterly.AI and AI Crawl Score occupy adjacent but distinct categories: Otterly.AI is a recurring, paid AI-mention monitoring service; AI Crawl Score is a free, single-run technical scanner.
What Otterly.AI does
Otterly.AI runs recurring search-prompt monitoring across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot, with Claude, Gemini, and Google AI Mode available as add-ons, reporting brand mentions, link citations, and sentiment week over week. Its tiers, per its own pricing announcement, start at a Lite plan covering 15 tracked prompts, scaling to Standard and Premium plans with more prompts, API access, and agent analytics, plus a custom Enterprise tier. Features include Citation Intelligence, Response Position Analysis, Share of Voice reporting, and schema guidance for improving AI-answer eligibility. It is a subscription product billed monthly or annually, built around ongoing prompt tracking rather than a single technical check.
What AI Crawl Score does
AI Crawl Score’s free readiness checker does not track prompts, mentions, or citations inside AI answers. It runs a single bounded raw-fetch scan of up to five pages, reporting robots.txt rules per crawler identity, sitemap presence, JSON-LD structured data, and delivered-content accuracy against what was intended. There is no recurring billing, prompt count, or account requirement to run a scan.

Which one fits your situation
Run AI Crawl Score’s scan when the question is a technical one-off: did a recent change break crawler access to key pages. Choose Otterly.AI when the ongoing question is commercial: how often and in what position does a brand appear across AI answer engines compared to competitors, tracked prompt by prompt over time. Google’s own AI-optimization guidance still anchors AI-era visibility in standard technical and content fundamentals, so a clean AI Crawl Score result is a reasonable prerequisite before investing in Otterly.AI’s recurring tracking, not a substitute for it.

Frequently asked questions
Is AI Crawl Score free forever, or is there a paid tier like the Otterly.AI one?
The readiness checker scan is free to run. It is a diagnostic tool, not a subscription monitoring product.
Does Otterly.AI check robots.txt or structured data on a site?
The Otterly.AI own documentation describes schema guidance as a feature, but its core product is AI-answer mention and citation tracking, not a general-purpose robots/sitemap scanner.
