  • Code-first workflows: Add support AI agents to your app in under 10 lines of code using the @cossistant/next package.
  • Customizable agent personality: Control the model, prompt, tone, and skills to match your brand voice.
  • Real-time inbox: Monitor conversations with live visitor tracking, response times, and AI intervention metrics.
  • Human escalation: Seamlessly transitions complex issues to human support when needed.
