about
Coval is a platform that helps you build and test AI agents. It allows you to simulate thousands of scenarios from a few test cases, providing AI-powered simulations for both text and voice AI agents. Coval offers comprehensive evaluations of agent interactions, allowing you to track performance over time and dive into specific runs to determine root causes. It also provides workflow metrics for observability into your system. The platform is built by experts in autonomous testing and is trusted by several companies.

Use Cases▌
Task Automation
Handle multi-step workflows autonomously
Example
Schedule meeting → Find time → Send invite → Confirm attendees
Save 5-10 hours/week on routine coordination tasks
Information Synthesis
Gather data from multiple sources and summarize
Example
Research competitor pricing across 5 websites, create comparison table
Reduce research time from hours to minutes
Decision Support
Analyze options and recommend actions
Example
Review 20 vendor proposals, score against criteria, rank top 3
Make data-driven decisions faster
Architecture▌
AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.
LLM Core
Large language model for reasoning and decision-making
Understand tasks, plan steps, generate responses
Tool Integration
APIs, databases, external services the agent can call
Take actions beyond text generation (search, compute, write files)
Memory System
Short-term (conversation) and long-term (persistent) memory
Maintain context across interactions and learn from past actions
Orchestration Logic
Decision engine for choosing next action
Plan multi-step workflows and handle errors/edge cases
Implementation Guide▌
Prerequisites
- ›Clear task definition and success criteria
- ›APIs and tools agent will need to access
- ›Approval workflows for sensitive actions
- ›Monitoring and logging infrastructure
Installation Steps
- 1.Define agent scope and capabilities
- 2.Integrate necessary tools and APIs
- 3.Build orchestration logic for task planning
- 4.Test with low-risk tasks in sandbox
- 5.Monitor performance and iterate
- 6.Scale to production use cases
Key Considerations
- →Security: What actions can agent take without approval?
- →Reliability: What happens when agent fails mid-task?
- →Cost: LLM API calls can add up at scale
- →Monitoring: How to detect and fix agent mistakes?
Best Practices▌
✓ Do
- +Start with narrow, well-defined tasks
- +Monitor agent actions and outcomes
- +Provide human oversight for critical decisions
- +Iterate based on real-world performance
- +Measure ROI: time saved, errors reduced, costs
✗ Don't
- −Don't deploy without testing edge cases
- −Don't give agent access to sensitive systems without safeguards
- −Don't ignore agent errors—investigate and fix root cause
- −Don't scale before proving value on pilot tasks
Performance & Optimization▌
Key Metrics
- Task completion rate: % of tasks agent completes successfully
- Time to completion: Agent vs. human baseline
- Error rate: % of tasks requiring human intervention
- Cost per task: LLM costs vs. human labor savings
Optimization Tips
- →Cache common workflows to reduce redundant LLM calls
- →Fine-tune decision logic based on failure patterns
- →Expand tool library to handle more use cases
- →Implement human-in-loop for high-stakes decisions
