Crew Chief (CrewChiefV4) listens to your session and speaks up like a real race engineer and spotter: fuel and pit-window calls, tire and damage warnings, gap and position callouts, and flag/incident alerts, all read out loud so you never have to glance at an overlay mid-corner. It supports a long list of sims through their native telemetry APIs.
The project is open source under the MIT license. Primary development has moved from the original GitHub mirror to GitLab, where releases are cut every few weeks.
With SimLauncher: Already listed as a companion-app pill on the SimLauncher homepage; add it as a custom app slot so it starts and connects right after your sim.
