Private dictation that never leaves your iPhone. KeySay is a voice keyboard that turns speech into text entirely on your device. Your voice is never uploaded, never stored on a server, and never used to train anyone's AI. There's no account to create and nothing to sign in to. 100% ON-DEVICE • Speech recognition runs locally, using the open-source Whisper speech model. • Dictation works with no internet connection. Try it in Airplane Mode. • No servers, no analytics, no tracking, no ads. We don't collect your data because we never receive it. DICTATE INTO ANY APP Switch to the KeySay keyboard in Messages, Mail, Notes, or anywhere you type. Tap the mic, speak, and your words appear. • Custom vocabulary: teach KeySay names, product terms, and jargon. • Your own fixes: tell KeySay which words it tends to mishear and what you meant. • Smart cleanup: on iPhones with Apple Intelligence, Apple's on-device model fixes misheard words and removes filler words. This runs locally too, never in the cloud. • A full keyboard when you need one: switch between a voice-only layout and a QWERTY keyboard with on-device autocorrect, emoji search, and a trackpad space bar. ABOUT "ALLOW FULL ACCESS" iOS doesn't let keyboards use the microphone, so the KeySay app does the listening and passes your text to the keyboard. That hand-off requires Full Access. When you turn it on, iOS shows the same generic warning it shows for every keyboard. KeySay has no servers to send anything to: your words go from the KeySay app to the KeySay keyboard and nowhere else. PAY ONCE, KEEP FOREVER KeySay is free to use with a daily dictation allowance. One purchase unlocks unlimited dictation forever. No subscriptions. Questions? Visit keysay.app
