Know when your voice agent is actually working
Monitor every production conversation. Evaluate every behavior that matters. Catch failures before they become patterns.
Evals & Guardrails
Define what "good" looks like. Score every call against it.
Define your criteria in plain language. Tuner scores every production call automatically — no sampling, no manual review. Run the same evals in simulation and production, so what you test is what you monitor.
30+ pre-built evals.
Cover common voice-agent failure modes out of the box, including hallucinations, scope boundaries, escalation handling, and out-of-hours behavior.
Custom Evals
Define the pass/fail criteria that matter to your business. Tuner scores every call against your rules.
Dynamic evals
Score each call against the instructions and context the agent actually received, with different expectations for each customer, session, or task.
See why it passed or failed
Every eval result includes the transcript evidence behind the verdict, so you can see exactly what happened instead of trusting an unexplained score.
Alerts
Know the moment something breaks
Catch problems as they happen instead of waiting for a report. Tuner alerts you on individual failures and patterns across your traffic.
Alert on any signal
Trigger alerts from intents, outcomes, extracted data, red flags, evals, or any metric Tuner computes. If Tuner can detect it, you can alert on it.
User-defined conditions
Build alert rules from multiple signals. For example: alert when hallucination is detected and sentiment drops below 3, or when 5+ calls fail identity verification within 10 minutes.
Catch failures and patterns
Alert immediately on a critical call, or when a problem starts appearing across calls — rising latency, increasing red flags, or falling resolution rates.
Route alerts where your team works
Send alerts to email, webhooks, or Slack.
Call Analysis
Understand every conversation automatically.
Extract the signals you need from every conversation — without manual labeling or sampling.
Know how every call ended
Detect outcomes such as resolution, escalation, abandonment, or incorrect action automatically.
Know what callers are asking for
Classify caller intent automatically and group conversations by type — Sales, Support, Onboarding, Billing, and more.
Extract the data you need
Pull dates, numbers, names, and custom entities from conversations and store them as queryable metadata.
Red Flags
Auto-tag failures the moment they happen.
Some failures can't be captured by a generic metric. Define your own rules in plain language and automatically tag the calls that match.
Build rules from any signal
Create rules using evals, metrics, extracted data, call metadata, or combinations of signals.
Surface high-risk calls
Flag calls where multiple signals point to a serious issue, so your team can focus on the conversations that need attention.
Create contextual labels
Tag patterns you want to track without treating them as failures.
