What it does

Tuner is a hosted observability, evaluation, and simulation platform for voice AI agents. Teams send it call data through a supported connection or the API; Tuner evaluates calls against built-in or custom criteria and displays transcripts, tool calls, timing, and evaluation results. Teams can also run simulated calls against an agent, review failures, and use scenarios as repeatable tests after changes.

Voice AI developers and teams operating agents can use dashboards and call logs to inspect performance, define alerts, and track extracted data and voice metrics. Connections include guided integrations, SDKs for Python-based stacks, and a direct API for other languages. Setup requires a Tuner API key, workspace ID, and agent’s Agent Remote ID. Free signup includes 300 one-time credits. Paid plans include monthly credits with metered overage; credit consumption depends on the job, so credits are not a fixed call allowance.

  • Evaluate production and simulated calls against predefined or custom criteria
  • Inspect call transcripts, tool calls, and per-turn timing
  • Track voice metrics and extracted call data
