Hey Product Hunt! 👋 I built WaveCrab because I kept doing something embarrassing: opening ChatGPT just to use its dictation feature, then copying the text and pasting it wherever I actually needed it. It worked beautifully — mixed languages, great accuracy — but the workflow was ridiculous. I wanted that exact experience system-wide. Speak into any app, any text field, without switching windows or touching the clipboard manually. The cloud-based options out there felt wrong to me. Your voice is personal. Why should it travel to a server every time you dictate a shopping list or write an email? So I built WaveCrab around OpenAI's Whisper running entirely on-device via whisper.cpp, with Metal GPU acceleration. Same model quality, zero data leaving your Mac. The result: hold a key, speak, release — text appears wherever your cursor is. In any app. In 29 languages. With no subscription and no cloud dependency. If you've ever wished ChatGPT's mic button worked everywhere on your Mac, that's exactly what WaveCrab is. Would love to hear your thoughts and answer any questions! 🦀
