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

A product trial is advertised, but there is no documented permanent free plan or standalone free SEO utility.

SEO Stuff
No documented API, agent protocol, SDK, tool-calling interface or autonomous agent feature for the exact product.
The official pages market visibility in “agentic search” but document user-facing research tools and human services, not an agent interface. https://www.seo-stuff.com/
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.

Deployment and one-click content workflows are highly streamlined, while human review/control remains part of the team workflow.
Semji says agents deploy in a few clicks and Atomic Content generates complete optimized content in one click; the product also emphasizes writers, comments, and collaboration: https://semji.com/ai-agents/; https://semji.com/features/atomic-content/
SEO Stuff
Self-serve keyword/backlink tools are relatively simple, but core AI-search execution is service-led and not autonomous software operation.
