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.

The AI docs explicitly recommend customization, fact-checking, and a human in the loop: https://www.contentharmony.com/docs/how-do-i-use-ai-suggestions/
