Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.
Clearscope
A free trial is available, but no permanently free standalone tool is documented.
The current pricing page states “14 day free trial” and links to Start for free; it does not list a perpetual free plan: https://www.clearscope.io/pricing
Siteimprove SEO
A separate free SEO Website Checker exists, but the core Siteimprove SEO product pages do not document free access to the enterprise platform.
Siteimprove's official toolkit describes a free checker that scans for 14 SEO errors: https://www.siteimprove.com/toolkit/seo-checker/

The support guide describes an editor providing real-time relevance/readability feedback and sharing for human collaboration; it does not document unattended publishing: https://www.clearscope.io/support/getting-started-editor
Siteimprove SEO
Automation is strong for audits, monitoring, reporting, and recommendations, but public evidence emphasizes human-guided optimization rather than autonomous end-to-end execution.
