The official feature pages describe conventional XML, HTML, image, video, and news sitemaps rather than AI-search optimization: https://www.xml-sitemaps.com/video-sitemap.html

The official homepage contains the AI recommendation positioning but does not document a dedicated GEO readiness feature: https://www.outrank.so/

The pricing page documents $99/month or $999/year, bundled inclusions, cancellation anytime, and trial access: https://www.outrank.so/pricing
XML-Sitemaps.com
Very accessible for small sites because it is free, requires no registration, and is browser-based.

Free tools
Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.

Agent readiness level
Automation
How ready the product is to operate as or inside an AI agent workflow, based on tracked subcriteria for autonomy, controls, integrations, memory, and evaluation.
Outrank
REST API and CLI support agent-driven operation, while planning, guardrails, memory, and evaluation remain narrower than a full agent platform.
The official API docs describe CLI and AI coding-agent use: https://www.outrank.so/docs/api
XML-Sitemaps.com
No agent, API, webhook, or machine-readable automation interface is documented for the online product.
The official workflow is entering a website URL and downloading generated files: https://www.xml-sitemaps.com/about-us.html
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.

Official product pages describe automated research-to-publish content workflows: https://www.outrank.so/
XML-Sitemaps.com
