Rhetor: Multi-agent system for rehearsed live product demos with real-time voice Q&A

Researchers introduce Rhetor, a multi-agent system that automates live software product demonstrations by taking a running web application and its source code as input, then producing a rehearsed demo with synchronized narration and real-time voice question answering. The system combines UI exploration with source-code analysis, uses semantic locators for browser action dispatch, and includes a pre-presentation rehearsal loop with graceful degradation. Evaluated across six pipeline sessions on four deployed applications, the system achieves high locator-firing rates (sigma-bar ~0.92 on a 53-action workload) and converges to perfect locator resolution on a public-domain reference app. The paper also proposes a ten-metric benchmark protocol for evaluating demo automation systems.
