Key Features
Any Harm Type, Any Scale
Review content across any policy category: harassment, spam, fraud, TVEC, or child safety. Coop's child safety workflow goes further with hash matching via HMA, NCMEC CyberTipline reporting, and integrations with Google Content Safety API and OpenAI Moderation API.
Queue Management
Content flagged by automated detection or user reports flows into review queues. Role-based access controls and routing rules make sure the right people see the right things.
Manual and Automatic Actions
Build rules for automation using your signals or route content to manual review. Complete audit logging of every decision for compliance and quality assurance.
Integration Ready
Works with your existing models, vendor signals, or as a standalone review console. Self-hosted, privacy-preserving, and built with reviewer wellbeing in mind.

Coop can also be run as a managed service by third-party providers. Musubi offers a hosted version today. If you provide a hosted version of Coop and want to be listed here, contact us.
