Test Every ElevenLabs Agent, From Widget to Phone Line

Chat & Web Widget
Inbound Calls
Outbound Calls

Test ElevenLabs Web and Chat Conversations

ElevenLabs agents often ship as a web widget or chat assistant first. Simulate thousands of multi-turn conversations and score every turn on 9 quality metrics.

Chat & Web Widget

Knowledge Grounding Checks

Confirm the agent answers from your uploaded docs and FAQs instead of inventing a policy, and catch hallucinations when a customer asks about a refund window or a clinic's hours.

Scenarios From Your Own Knowledge

Ingest PDFs and text or connect Confluence, Jira, and GitHub, then auto-generate the scenarios and edge cases your agent will face, like a caller switching languages mid-conversation.

Go-Live Assessment

Get a Green, Yellow, or Red production-readiness verdict with customizable 0-100% pass/fail thresholds before the agent goes live.

From the First Hello to a Booked Appointment

From Web Widget to Phone Line, End to End

An ElevenLabs agent often ships as a web widget, then bridges to Twilio or SIP for calls. Run simulated conversations and live test calls before launch, then batch-analyze real recordings with the same metrics, so the same brain holds up on every channel.

From Web Widget to Phone Line, End to End

Quality Coverage Built for Low-Latency Voice

ElevenLabs sells on sub-second response and natural turn-taking, so latency and barge-in are make-or-break. Score chat on 9 quality metrics and calls on 30+ flow, accuracy, audio, and speech-to-text metrics.

Quality Coverage Built for Low-Latency Voice

UX and Business Ops Metrics

Track CSAT and detected sentiment, containment rate, early-termination rate, and how often the agent hands a caller to a human instead of resolving the booking or query itself.

UX and Business Ops Metrics

Go-Live Assessment by Confidence

Get a Green, Yellow, or Red verdict from four weighted dimensions, with confidence levels scaled to evaluation volume, before the agent answers a real customer call.
