§ 03LIVE MONITORING

Stop listening to calls. Get notified.

Every live call is silently logged and analysed. You get real-time alerts the moment something drifts — so you can address problems before they reach more users. As one customer put it: monitoring is the hidden gem. No more daily audits. No more spot-checks. Just eyes-on when it matters.

§ 08FAQ

Frequently asked.

What is automated testing?
Automated testing for AI voice agents means evaluating the agent's performance, accuracy, and responsiveness using pre-defined scripts and test cases without human intervention. It ensures the voice agent understands spoken input correctly, responds appropriately, and handles various scenarios such as interruptions or errors.
What is automated monitoring?
Automated monitoring continuously tracks your voice agent's performance to ensure it's functioning correctly at all times. With Relyable, every call is logged and analysed, giving you full visibility into interactions and outcomes. You'll receive real-time alerts if issues arise, so you can quickly address problems before they impact more users.
Why do I need this?
Manually calling and evaluating voice agents is time-consuming, repetitive, and prone to human error. Using AI to run these tests makes the process far more efficient and scalable as your system grows. It also ensures more consistent, thorough coverage of scenarios — leading to better overall performance and reliability.
How is a call evaluated?
Calls are evaluated against customisable test cases that you can define, or generate from your system prompt to align with your specific business goals. Each interaction is automatically analysed using built-in metrics like latency, sentiment, and customer satisfaction — allowing for precise, consistent assessment across scenarios.
Which voice agent platforms do you connect with?
We offer native integrations with leading platforms like Vapi, Retell, and ElevenLabs — with many more on the way. Connecting is simple: just use your API key and agent ID. For custom-built agents on other platforms, upload your prompt manually and we'll route calls through our API while enabling real-time call monitoring.
Who is Relyable for?
Relyable is built for AI agencies, AI startups, and enterprises. Agencies use it to deliver higher-quality solutions faster and unlock new revenue through client upsells. Startups and SaaS teams integrate and scale voice agents with dependable monitoring. Enterprises rely on Relyable for continuous simulation, evaluation, and monitoring at scale.
Is it easy to use?
Yes. Relyable is designed to help you quickly improve the performance of your AI agents with minimal setup. You can start running your first test calls in under five minutes.
Why should I work with Relyable?
This isn't our first experience with voice agents. For nearly two years we've been developing AI voice agents through our agency, Inflate AI. During that time we honed our expertise in building high-performing voice systems — and realised the critical importance of prioritising evaluations. Relyable is the tool we wished we'd had.
