How It Works

1

Get a Phone Number

We provision a real DID. Build your test scenarios using our visual dialplan builder or AI agents.

2

Call with Your Agent

Have your voice AI call the number. Test against IVR trees or AI agents simulating real humans.

3

Review & Export Training Data

Review transcripts, correct responses, and export to OpenAI for fine-tuning your custom model.

Built for Systematic Testing

Everything you need to test voice AI agents at scale and generate high-quality training data.

Deterministic IVR Scenarios

Build phone trees with predictable paths. Set success goals and track completion rates.

AI Agent Testing

Create AI responders that simulate real humans answering the phone. Test natural conversations.

Performance Benchmarking

Track success rates, measure goal completion, and benchmark across test runs.

Repeatable Test Cases

Save scenarios as "gyms" - reusable test suites you can run repeatedly.

Human-in-the-Loop Review

Review transcripts, correct agent responses, and build a gold-standard dataset.

Export Training Data

Export reviewed conversations directly to OpenAI for fine-tuning your custom models.
