General Questions

Tuner is an analytics and observability platform for voice AI agents. It helps you understand how your agents are performing in real-time, identify issues, and get the insights you need to improve the user experience.
Tuner is designed for developers, product managers, and business teams who are building and managing voice AI agents. Whether you’re a startup or a large enterprise, Tuner provides the tools to monitor and optimize your voice applications.
Tuner integrates with your voice AI platform to automatically ingest call data.
  • For supported platforms like Retell, this is a one-click setup.
  • For custom-built voice agents, you can use our simple API to send call data to Tuner.
Once the data is in Tuner, it’s processed to provide transcripts, sentiment analysis, evaluations, and metrics on the Overview dashboard.
We offer a seamless, no-code integration for Retell, an SDK for LiveKit Agents, an SDK for Pipecat Flows, and we are actively working on adding support for other platforms like Vapi. For all other custom voice AI stacks, you can use our Public API.
Tuner provides a comprehensive view of your agent’s performance, including:
  • High-Level Metrics: Total calls, success rate, average call duration.
  • Call Analysis: User intent, call outcomes, and sentiment trends.
  • Issue Detection: Red flags for issues like hallucinations, high latency, and agent loops.
  • Drill-Down Capabilities: Full transcripts and evaluation results for every call.

Technical Questions

You can find our complete API documentation with code examples in the API Reference section.
  • Workspace ID: This is a unique identifier for your entire workspace (your company or team account) in Tuner. It’s used in API calls to ensure data is sent to the correct account.
  • Agent Remote Identifier: This is the unique ID of a specific agent from your own system. You provide this ID when you send call data so Tuner can associate the call with the correct agent you’ve configured.
  • Workspace ID: You can find your Workspace ID in your Tuner dashboard under Worspace Settings > General.
  • Agent Remote Identifier: This is an ID from your own system that you define. When you create an agent in Tuner, you provide this ID so we can link the data correctly.

​
Billing and Credits

Tuner uses a credit-based pricing model. You purchase credits, and each call processed by Tuner consumes credits. This pay-as-you-go approach means you only pay for what you use.
Credits are consumed each time a call is processed through Tuner. When you send call data via our API or through an integration like Retell, the call is analyzed and credits are deducted from your balance.
You can purchase additional credits at any time from the Settings > Billing page in your Tuner dashboard. Credits are added to your account immediately upon purchase.
When your credit balance reaches zero, new calls will not be processed until you add more credits. You’ll receive notifications as your balance gets low so you can top up before running out.
Yes, you can view your credit balance and usage history in the Settings > Billing section of your dashboard. This includes a breakdown of credits consumed per agent and over time.
