That’s exactly why we built WhisKey — a dictation app that actually respects your privacy. No creepy servers, no mystery “cloud” holding your conversations. Everything happens right on your iPhone or iPad, powered by some seriously clever AI. Think of it as having a super-fast, multilingual secretary living in your pocket — except this one never sends your voice to strangers, doesn’t need Wi-Fi, and works in 12+ languages. Chinese, English, Japanese, Korean, French, German… even if you switch mid-sentence, it’ll keep up. And it’s not just about privacy — it’s fast. Tap record, speak naturally, and within seconds your words are on screen, ready to drop into Messages, WhatsApp, Notes, or wherever you need them. We even built a custom keyboard so you don’t have to leave the app you’re in. Different situations? Different brains. WhisKey lets you pick from lightweight models for quick notes or big powerful ones when accuracy matters most. You download only what you need, so your storage (and patience) stays intact. We also made it playful — the Dynamic Island lights up with recording status, and there’s even a step-by-step video tutorial built right in. No manuals, no headaches. Just tap, talk, and watch your voice become text. So whether you’re a student turning lectures into notes, a creator capturing podcast ideas on the fly, or just someone who values their privacy (and hates typing with thumbs), WhisKey was built for you. And yes, we promise: your voice never leaves your device. What you say is yours — and only yours. Subscriptions will automatically renew unless canceled at least 24 hours before the end of the current period.
