Hey Product Hunt 👋 I'm Mustapha, and I built SpeechFast because I wanted to dictate on my Mac without my voice going to someone else's server. How it works: hold fn, talk, let go. Clean text appears at your cursor, in whatever app you're in: Mail, Slack, Notion, your code editor, a terminal. What makes it different with SuperWhisper or WisprFlow: 100% on-device. Transcription runs on your Mac's chip, with the NVIDIA Parakeet model. It's downloaded once; after that, SpeechFast works offline, even in airplane mode. An automated test fails the build if a single request leaves the Mac during a dictation. - Hands-free mode for longer thoughts, and a local history of your recent dictations. It needs a Mac with Apple Silicon (M1 or later) running macOS 26. I'd love your feedback, especially on accuracy in your language and on the apps where pasting doesn't behave. One more thing: if you know a local speech model that runs well on Apple Silicon and beats Parakeet for your language or use case, please tell me. I'm always testing new ones, and the best suggestions will make it into the app. I'll be here all day answering questions.
