Why Relyable?
Most AI voice agents sound great in testing and then fall apart the moment they hit the real world. You make a few test calls, everything works perfectly, then you deploy it to production and suddenly you’re dealing with edge cases, unexpected user responses, and frustrated customers. That’s where Relyable comes in. Relyable is an automated AI voice agent testing and monitoring platform that helps you build, test, and deploy voice agents that are actually production-ready. We’ve been using it internally for months alongside beta testers, and it has saved us countless hours while eliminating some of the biggest headaches in AI voice agent development.The Problem We’re Solving
When you’re building AI voice agents, manual testing only gets you so far. You can:- Make 5-10 test calls yourself and think everything works perfectly
- Deploy to production
- Watch as your agent fails 40% of the time with real users
- Different accents and speaking styles - Your Australian accent is very different from an elderly American customer
- Stressed or frustrated users - People don’t always speak politely to voice agents
- Edge cases - “I need to sell my house but also buy one, and my grandson needs to rent”
- Scale - What works for 10 calls might fail at 100 or 1,000 calls
What Relyable Does
Automated Testing
Run hundreds of realistic test calls with different personas, accents, and scenarios to find issues before your customers do.
Test Case Evaluation
Automatically evaluate every conversation against your custom test cases to ensure your agent follows the script every time.
Live Monitoring
Monitor production calls in real-time and get alerted when critical failures occur or performance drops.
Smart Personas
Create realistic caller personas with different ages, accents, personalities, and stress levels to stress-test your agent.
Key Features
🎯 Test Case Generation
Automatically generate test cases from your prompts, or create custom ones. Each test case is evaluated on every call with priority levels (Critical, High, Medium, Low).🎭 Realistic Personas
Create personas like “Stanley, a 79-year-old frustrated retired mechanic” or “Sarah, a 23-year-old tech-savvy professional” to simulate real customer diversity.📊 Performance Scoring
Get detailed scores on every call based on:- Test case pass/fail rates
- Average latency
- Words per minute
- Conversation quality metrics
🔗 Direct Integration
Works seamlessly with Vapi and Retell AI - just plug in your API key and assistant ID.📈 Production Monitoring
Enable call monitoring to evaluate real customer calls against your test cases and get notified of failures.How It Works
1
Import Your Agent
Connect your Vapi or Retell agent by providing your API key and assistant ID. Relyable automatically syncs your prompt and configuration.
2
Generate Test Cases
Let AI analyze your prompt and generate 15-20 test cases, or create custom ones for specific scenarios you want to validate.
3
Create Personas
Build realistic caller personas with different demographics, personalities, and speaking styles to simulate your actual customer base.
4
Run Simulations
Create scenarios and run automated test calls. Watch as your agent handles everything from smooth conversations to difficult customers.
5
Analyze Results
Review detailed transcripts, recordings, and scores. See exactly which test cases failed and why, with AI-generated improvement suggestions.
6
Iterate & Improve
Update your prompt in Vapi/Retell, sync to Relyable, and test again until you achieve 70%+ scores consistently.
7
Monitor Production
Enable live monitoring to evaluate real customer calls and get alerted to issues before they impact your business.
Real Results
From the demonstration in the video, an agent that seemed to work perfectly in manual testing scored only 51-61% when stress-tested with automated scenarios. Issues discovered included:- Skipping required questions in the conversation flow
- Not confirming captured information (names, addresses)
- Giving up on difficult customers prematurely
- Failing to follow conditional logic in prompts
