As answered by people managing Drift and Evalgent.
Evalgent's answer:
Evalgent doesn't just tell you if your AI voice agent passed — it maps exactly where and why it fails under real human behavior.
Evalgent's answer:
Most voice agent QA tools tell you a test passed or failed — Evalgent shows you under what conditions your agent starts to break and what to fix before deployment.
Evalgent's answer:
Evalgent is built for AI voice agent developers and product teams using Vapi, Retell, LiveKit, Pipecat, Deepgram and ElevenLabs — teams that have built an agent and need to know it works before real users call. QA engineers and voice AI product managers shipping agents at production scale are the core users.
