## General Questions

<Accordion title="What is Tuner?">
  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.
</Accordion>

<Accordion title="Who is Tuner for?">
  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.
</Accordion>

<Accordion title="How does Tuner work?">
  Tuner integrates with your voice AI platform to automatically ingest call data.

  * For supported platforms like **Retell** and **Vapi**, 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.
</Accordion>

<Accordion title="What voice AI platforms do you support?">
  We offer seamless, no-code integrations for **Retell** and **Vapi**, an SDK for **LiveKit Agents**, an SDK for **Pipecat**, [**Dograh**](/docs/integrations/dograh) (export from your Dograh workflow to Tuner via the **Tuner** integration node), and we are actively working on adding support for more platforms. For all other custom voice AI stacks, you can use our **Public API**.
</Accordion>

<Accordion title="What kind of insights can I get from Tuner?">
  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.
</Accordion>

## Technical Questions

<Accordion title="Where is your API documentation?">
  You can find our complete API documentation with code examples in the [**API Reference**](/docs/api-reference/create-call) section.
</Accordion>

<Accordion title="What is the difference between a Workspace ID and an Agent Remote ID?">
  * **Workspace ID**: A unique identifier for your entire workspace in Tuner. Used in API calls to route data to the correct account.
  * **Agent Remote ID**: A unique identifier that links a specific agent in Tuner to its counterpart on your voice platform. How this works depends on your provider — see below.
</Accordion>

<Accordion title="How do I find my Workspace ID and Agent Remote ID?">
  * **Workspace ID**: Found in your Tuner dashboard under **Workspace Settings > General**.
  * **Agent Remote ID**: Depends on how you're sending call data to Tuner:
    * **Retell, Vapi, or other webhook-based providers**: Copy the agent ID from your provider's dashboard and paste it when creating an agent in Tuner. This lets Tuner match incoming calls to the right agent.
    * **Custom API (LiveKit, Pipecat, etc.)**: Tuner auto-generates this ID for you when you create an agent. Use it in your API requests to attribute calls to the correct agent.
</Accordion>

## Security & Privacy

<Accordion title="How does Tuner handle sensitive caller data (PII)?">
  On the **Growth plan**, workspace admins can turn on **PII redaction**. Tuner then automatically detects sensitive details in each call transcript — names, phone numbers, email and physical addresses, SSN / national ID, card numbers, and spoken PINs or passwords — and replaces them with labels like `[NAME]` before the transcript is stored. The original, unredacted transcript is never kept, and all analysis runs on the clean version.

  The setting is workspace-wide, so it applies to every agent in the workspace. See [**Data Redaction (PII)**](/docs/observability/pii-redaction) for the full walkthrough.
</Accordion>

## Billing and Credits

<Accordion title="How does the pricing work?">
  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.
</Accordion>

<Accordion title="How are credits consumed?">
  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.
</Accordion>

<Accordion title="How do I purchase more credits?">
  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.
</Accordion>

<Accordion title="What happens when I run out of credits?">
  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.
</Accordion>

<Accordion title="Can I see my credit usage?">
  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.
</Accordion>
