The integrations page documents shareable links and export/copy to Google Docs, Microsoft Word, and project-management tools: https://www.contentharmony.com/integrations/

Content Harmony
No numeric first-party customer/adoption claim was found.
The official case-study and testimonial pages provide qualitative customer comments but no customer-count figure: https://www.contentharmony.com/results/

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/

Very low operational burden: the site claims a 30-second order and handles the workflow end to end, while still offering approvals and custom requirements.
https://respona.com/ says '30 seconds to order' and describes end-to-end fulfillment; https://respona.com/pricing/ documents customization, approvals, anchors, URLs, and custom requirements.
