Prove your voice agents are ready — with simulation, production evals, and human QA in one loop
Pressure-test agents with thousands of realistic callers, accents, interruptions, noisy audio, and hard policy traps that manual QA cannot cover.
Run evaluations on live conversations to spot where resolution, safety, or customer experience is slipping before complaints arrive.
Route the calls that matter to human reviewers and convert their judgment into sharper automated metrics for the next release.
Compare voice agent vendors and prompts side by side on the same behavioural criteria before deciding.

Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
