  • Multi-step workflow automation: Build agents that handle complex, multi-intent requests — querying systems, applying business logic, and executing actions without human intervention.
  • Legacy system orchestration: Connect AI agents to older CRM or ERP systems via API to retrieve and update records autonomously.
  • Knowledge base RAG pipelines: Ground agent responses in live documentation from help centers, Google Drive, or uploaded PDFs for accurate, policy-aligned answers.
  • Automated QA pipelines: Use built-in QA scoring to programmatically audit every agent interaction against defined policies and quality thresholds.
  • Cross-platform deployment: Deploy agents beyond Zendesk into any service environment using Forethought or REST API integrations.
  • Continuous model refinement: Leverage the Resolution Learning Loop to automatically detect failing procedures and improve agent performance from production outcome data.
