Hey Product Hunt! 👋 I built Whisper STT because I was tired of uploading sensitive audio to cloud transcription services. Every meeting recording, voice memo, or interview I transcribed was being sent to someone else's server. So I built a tool that runs OpenAI's Whisper model directly in your browser — no data ever leaves your device. Here's what makes it different: 🔒 100% private — audio is processed locally, never uploaded ⚡ 3 model options — choose between speed and accuracy 🌍 99+ languages with translation to English 📶 Works offline after the first model download 💰 Completely free — no accounts, no API keys, no limits The tech stack: Astro static site + React islands + Transformers.js + Web Workers. The AI runs on WebAssembly so your browser tab stays responsive. Would love your feedback — what features would you want to see next? 🙏
