What to expect from an ideal product

  1. Record your AI agent interactions locally so you can replay them later without making new API calls
  2. Run debugging sessions completely offline using previously captured data instead of hitting live endpoints
  3. Analyze failed agent behaviors by stepping through recorded conversations without spending money on retries
  4. Track exactly how much each agent run costs before deploying to production environments
  5. Test different debugging scenarios using the same recorded data multiple times at zero additional cost
