    About Tuner

    The Observability and Analytics Platform for Voice AI

    Tuner provides full production visibility for voice AI agents, enabling users to catch failures early, understand agent behavior, and measure real impact. It offers tools to understand, monitor, and improve voice agents at scale by turning conversations into clear, explainable signals.

    Key Features

    • Live Hallucination Detection: Identify when the agent generates incorrect information.
    • Cost Spikes Detection: Monitor for unexpected increases in operational costs.
    • Continuous Agent Improvement: Use real data to improve prompts, tools, and flows.
    • Agent Health Tracking: Keep a constant watch on the overall performance of your agents.
    • Business Impact Metrics: Measure the real-world impact of your voice AI.
    • Stakeholder-Ready Reports: Generate reports suitable for business stakeholders.
    • Performance Heatmaps: Visualize agent performance to identify patterns.
    • Agent A/B Testing: Compare performance across different versions and deployments.
    • Production Agent Observability: Gain full visibility into your voice system in a live environment.
    • Regression Monitoring: Spot regressions and validate improvements early.
    • Missed Intent Detection: Detect when the agent fails to understand the user's intent.
    • Live Call Monitoring: Monitor conversations as they happen.
    • Instant Failure Alerts: Get immediate notifications for failures, behavior changes, or performance issues.

    Core Capabilities

    • Understand Agent Activity: Convert every call into structured, queryable signals to evaluate interactions across intent, outcome, behavior, and quality. See what users asked and how the agent responded.
    • Proactive Problem Detection: Monitor calls for unexpected or risky patterns, including missed intents, hallucinations, broken flows, and cost spikes. Move from reactive debugging to early detection.
    • Unified Operational View: Bring all voice agent data into a single, unified view. Track performance, failures, and trends across agents and build dashboards from system health to deep dives.
    • Data-Driven Improvement: Track the impact of prompt, configuration, and model changes. Compare performance across versions to validate improvements and balance quality, latency, and cost.

    Getting Started

    Tuner can be set up in minutes. Connect your agent by adding an API key to start ingesting calls. The platform works with Retell, Vapi, and custom stacks. Users can start with pre-built templates or create custom configurations for alerts, guardrails, and success criteria.
