A 24/7 Radar for Your Production Voice Agents.
Don’t wait for customers to complain to know your agent is failing. Tuner monitors every live call, flags logic errors and performance drops the moment they happen, and routes alerts to your team in seconds.
Get Started
EVALUATION FRAMEWORK
Define What ‘Good’ and ‘Bad’ Look Like — Then Let Tuner Enforce It.
Tuner turns your business requirements into automated rules that grade every conversation as it happens. No audio review. No manual spot-checks. Continuous enforcement at scale.
✓
Compliance Checks
Automated pass/fail rules verify your agent followed the script, delivered required disclosures, and stayed within boundaries — on every call, not just the ones you have time to review.
✓
Latency & Audio Scoring
Response times, silence gaps, and hesitation patterns scored per call — catching performance issues that only show up in the audio, not the transcript.
✓
Call Labeling & Red Flags
Tag every call automatically — by intent, outcome, failure type, or custom label. Spot where conversations break down, where flow feels unnatural, and where customers get frustrated before they churn.
✓
Categorized Insights
Group calls by type — Sales, Support, Onboarding — to pinpoint exactly where drift is hitting hardest.
✓
Monitor Multiple Agents
Run separate monitoring configurations for each agent in your workspace. See every call, for every agent, in one place. (Agent comparison dashboard coming soon.)
REAL-TIME ALERTS
From Red Flag to Slack Message in Seconds.
By the time a daily report surfaces a problem, hundreds of calls have already failed. Tuner fires alerts the moment something breaks — so you fix it while it’s still a spark, not a fire.
✓
Per-Call Alerts
Instant notification the second a call breaches a guardrail or triggers a red flag. No batching, no delay.
✓
Pattern-Based Triggers
Volume thresholds catch systemic issues — 10+ failures in an hour means something is wrong at the system level, not just one bad call.
✓
Multi-Channel Routing
Push alerts to Slack, email, or both — wherever your team already lives.
✓
Operational Control
Pause, activate, or adjust rules on the fly. Change your monitoring posture without touching a deployment.
✓
Last-Trigger Tracking
Full audit trail with timestamps of when each alert last fired — so you can prove the system caught it, and when.
