Give Your Sim Race a Live Broadcast Booth
EWSR Race Cast is a Windows broadcast-companion app that turns live sim-racing telemetry into broadcast-style commentary, driver stories, voice output, and post-race logs.
Designed to make sim racers, creators, and leagues feel like a professional broadcast booth is following the action live.

What You'll Hear
Built around what your race feels like in the moment — not just what the software is doing behind the scenes.
Live Race Storytelling
Race Cast follows every position change, battle, and pit decision — narrating your race as it unfolds.
Three-Voice Broadcast Booth
A caller, analyst, and pit lane reporter work together with natural dialogue, callbacks, and topic awareness.
Personal Driver Name Packs
Hear YOUR name called during the race. One pack included free with Pro.
Battle & Overtake Recognition
Every wheel-to-wheel moment gets called. Side-by-side battles, lunges, and clean passes.
Multi-Sim Support
Works with Project Motor Racing (PMR), iRacing, Automobilista 2 (AMS2), Le Mans Ultimate (LMU), Assetto Corsa Competizione (ACC), RaceRoom Racing Experience (R3E), and rFactor 2 (rF2). Assetto Corsa and Assetto Corsa EVO are pending certification. Rennsport is planned.
Local-First Voice & Logging
Race telemetry is processed locally on your machine. Cloud features are optional and clearly disclosed.
Creator-Ready Race Recaps
Full session logs and race summaries ready for YouTube, Twitch, or league broadcasts.
Professional Commentary & Decision Logs
Every commentary decision is logged — see exactly what Race Cast detected and why it said what it said.
Three-Voice Booth
Not a monotone narrator — a caller, analyst, and pit lane reporter with banter, callbacks, and topic awareness.
Marvin Makai
Caller
Play-by-play, action moments, lead changes. The voice that captures the drama as it happens.
Marley Mae
Analyst
Strategy, driver arcs, colour commentary. The voice that gives the race depth and context.
Reese Raines
Pit Lane Reporter
Live weather, pit stops, tyre changes, fuel strategy. Reporting from the action with confident personality.
