Test Every Bland AI Pathway and Call. One Platform.

Pathway & Conversation
Inbound Voice
Outbound Voice

Test Your Bland AI Conversational Pathways

Bland agents follow node-based Conversational Pathways. Simulate thousands of callers and score every turn on 9 quality metrics to prove each branch behaves.

Pathway & Conversation

9 Quality Metrics

Score bias, hallucination, completeness, context awareness, response quality, conversation flow, user satisfaction, file handling, and file generation accuracy on every turn, so a missing knowledge node never becomes a guessed answer.

Branch and Loop Coverage

Auto-generate scenarios from your PDFs, Confluence, Jira, or GitHub and drive callers down every branch, including reschedules, cancellations, and the edge cases your decision nodes were built to catch.

Go-Live Assessment

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

From the First Ring to Full Production

Pre- and Post-Launch, End to End

Rehearse every pathway with simulated callers and live test calls before you flip the inbound number on, then batch-analyze the real recordings with the same metrics, so quality holds from the first pilot call to a full outbound campaign.

Pre- and Post-Launch, End to End

Total Quality Coverage for Bland Agents

Score pathway conversations across 9 quality metrics and phone calls across 30+ flow, accuracy, audio, and speech-to-text metrics, from branching logic to how the agent sounds on the line.

Total Quality Coverage for Bland Agents

Caller Experience and Ops Metrics

Track CSAT and detected sentiment, containment rate, early-termination rate, and how often a call escalates to a live human transfer across every Bland conversation.

Caller Experience and Ops Metrics

Go-Live Assessment by Confidence

Get a Green, Yellow, or Red verdict from four weighted dimensions, with confidence levels scaled to how many calls you tested before launch.

  • Live test calls into your inbound line
  • Passive monitoring and outbound number pool
  • Batch analysis of production recordings

TestMu SCENARIO & VOICE CONFIGURATIONSCENARIO & VOICE CONFIGURATION

Configure Scenarios and Voices

Shape each test to mirror the real world a caller answers in: generate scenarios from your own knowledge, pick a cloned or library voice, layer background noise, and control call flow down to response timing.

Try for free
  • Auto-generated scenarios and a persona library
  • 15 background-noise presets for resilience
  • Masked numbers and call-flow controls

TestMu AUDIO, STT & ISSUE DETECTIONAUDIO, STT & ISSUE DETECTION

Catch Failures Automatically

Beyond pass and fail, the platform surfaces exactly why a call broke, from a hallucinated policy or wrong-branch route to a stalled webhook, patchy audio, or incorrect speech-to-text, with precise mismatch logging.

Some Love from our Customers

As Best Egg expanded its product offerings and entered new markets, we knew our old testing infrastructure couldn’t keep up.
With support from Tenny Agustin, our Engineering Operations Lead, we modernized our approach with @testmuai see more >
