» Why I'm Building This
I’m hard of hearing, and after years of gaming I know how frustrating it is to miss callouts. I’ve always wanted to fully join fast, chaotic multiplayer matches — but the existing tools just don’t cut it.
Your team is shouting directions and enemy positions, and you’re stuck asking for repeats or guessing.
I built CaptionsRush so I could finally follow my squad in real time. No hacks — just captions that match the pace of the game. If that’s your struggle too, it’s for you.
