Deploy AI agents on existing platforms — Use the Zendesk + Forethought integration to run self-improving agents on your current service stack without platform migration.
Orchestrate cross-system workflows — Connect agents to CRMs, order management systems, and legacy tools via API to execute end-to-end resolutions (e.g., issue refunds, update records) autonomously.
Build no-code procedures in natural language — Describe complex support flows in plain text and let the platform auto-generate dynamic multi-intent procedures for agent execution.
Automate QA at scale — Programmatically enforce interaction policies and retrieve automated scoring data to maintain quality across thousands of daily AI-handled tickets.
Ground agents in live knowledge — Sync AI agents with Google Drive, PDFs, and Zendesk Help Center so answers always reflect the latest product and policy changes.
Analyze resolution patterns for continuous improvement — Leverage the Resolution Learning Loop to identify failing procedures, detect knowledge gaps, and auto-refine agent behavior based on outcomes.
