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.
Google Ads Keyword Planner
Guided workflows exist, but the user must operate the tool and finalize campaign actions.

Little Warden
Once configured, recurring checks and alert routing operate without manual checking, though remediation remains human-led.
