NovaSynth by Noveum

NovaSynth by Noveum is a self-service platform for testing voice AI agents with configurable AI callers and repeatable scenarios. Run single or batch calls to an authorized phone or LiveKit endpoint, simulate interruptions and background noise, then inspect recordings, transcripts and evaluations. Rerun scenarios after agent changes for regression testing. An account and a configured, reachable endpoint are required. Freemium includes 2,500 shared credits/month; calls consume 100 credits/minute and evaluations may use additional credits. Pro starts at $69/month.
