A technical scanner and a content-writing platform solve different problems
Frase and AI Crawl Score both get mentioned alongside “AI search” work, but Frase is a paid tool for researching and drafting content that ranks, while AI Crawl Score is a free tool for checking whether a site’s existing pages are technically reachable by crawlers.
What Frase does
Per Frase’s own pricing page, the platform is sold on Starter, Professional and Scale monthly plans, each including SERP analysis, AI-assisted content briefs and outlines, and AI writing tools intended to help content rank on Google and get cited by AI platforms such as ChatGPT and Perplexity. An optional FraseCMS hosting add-on is sold separately. It is a subscription content-research and drafting workflow, not a crawler-access checker: it does not report robots.txt rules, sitemap status, or structured-data validity for a site.
What AI Crawl Score does
AI Crawl Score’s free readiness checker does not research keywords, generate briefs, or write content. It runs a single bounded raw-fetch scan of up to five pages, reporting robots.txt directives by crawler identity, sitemap presence, JSON-LD structured data, and whether delivered HTML matches what was intended. There is no account, subscription, or credit system to run a scan.

Which one fits your situation
Use AI Crawl Score when the question is whether a page a writer already finished is actually crawlable and technically sound: is it noindexed by mistake, is JSON-LD present and valid, does the sitemap list it. Use Frase when the task is researching a topic, building a content brief from competing pages, and drafting new copy. Neither substitutes for the other: a well-researched Frase brief turned into a published page can still be blocked by a stray robots.txt rule, which is exactly what AI Crawl Score’s scan is built to catch. Google’s AI-optimization guidance treats sound technical fundamentals and useful content as complementary requirements, not substitutes.

Frequently asked questions
Does AI Crawl Score help write or optimize article content like Frase?
No. AI Crawl Score reports technical crawler-access findings only; it does not generate briefs, outlines, or drafted copy.

The published feature set of Frase, per its own pricing page, centers on SERP research, briefs and AI writing. It is not described as a robots.txt or structured-data scanner.
