Screamer is a free, open-source macOS app that turns your voice into text instantly. Hold a key, talk, release, words appear wherever your cursor is. Built in Rust with whisper.cpp, it runs entirely on-device using Metal GPU acceleration. No cloud, no subscriptions, no accounts. Up to 3x faster than paid alternatives. Your voice never leaves your machine. The AI models are free and open source, so the app is too.
