What is Relyable?
Relyable offers an end-to-end solution for ensuring voice agent quality: by creating test cases, defining user personas, and generating dialogue scenarios that cover all possible paths, it enables hundreds of test calls to run concurrently. All calls are scored in real time, triggering threshold-based alerts to ensure issues are detected before they impact more users. It supports native integrations with mainstream platforms like Vapi, Retell, and ElevenLabs, and is also compatible with self-built voice agents—simply upload prompt words, route calls to designated numbers, and invoke the API to enable real-time monitoring.
Key features
It supports a five-step process for simulation testing: create test cases → define roles → generate dialogue scenarios → assign roles to scenarios → and run hundreds of test calls in parallel, covering the entire interaction matrix at once.
It provides real-time monitoring capabilities: each voice call is automatically recorded, analyzed, and scored, with alerts triggered only when performance metrics exceed predefined thresholds, helping teams quickly identify issues such as semantic comprehension drift, response delays, or workflow interruptions.
Use cases and audience
AI agent development agencies, AI startups, SaaS teams, and large enterprises—agencies use it to improve delivery quality and drive customer upselling; startups and SaaS teams leverage it for scalable integration and reliable monitoring; enterprises employ it for large-scale continuous simulation, evaluation, and oversight.
- Automatically tests the performance, accuracy, and responsiveness of AI voice agents, ensuring they correctly interpret voice inputs and respond appropriately.
- Continuously monitor the real-time performance of voice agents and issue instant alerts for abnormal calls to prevent issues from escalating and affecting more users.
- Upload prompts to voice agents built on other platforms, and use the Relyable API to enable call routing and real-time monitoring.
Test cases, role definitions, and scenario prompt words; for self-built agents, users can also upload custom prompt words and configure API calls.
Real-time call scoring, anomaly threshold alerts, complete call logs, and analytical reports.
