About

WithVoice

WithVoice is an AI dictation keyboard that turns speech into polished textβ€”right where you're already typing. Tap the mic, talk naturally, and WithVoice inserts clean, punctuated sentences at your cursor in any app: Messages, Notes, Mail, Slack, your browser, anywhere. It supports both Korean and English input. Powered by Google Gemini, WithVoice does more than transcribe. It cleans up filler words, fixes punctuation, and formats your speech into text that's ready to sendβ€”so you spend less time editing and more time getting things done. WHY WITHVOICE β€’ Speak, don't type. Dictate emails, notes, and messages 3x faster than thumb-typing. β€’ Clean output, not raw transcript. Gemini removes "um," "uh," and false starts, then adds proper punctuation and capitalization. β€’ One keyboard for Korean and English. Switch languages with the "ν•œ/A" keyβ€”no need to change keyboards. The standard Dubeolsik layout composes final and compound consonants and vowels naturally, and the mic stays in the same spot in both. β€’ Works everywhere. As a system keyboard, WithVoice drops text into any app with a text field. β€’ Your key, your control. Bring your own Google Gemini API key. Audio and text go straight to Google's API and nowhere else. β€’ No accounts, no tracking. There are no logins, no ads, and no third-party analytics. HOW IT WORKS 1. Get a free Google Gemini API key and paste it into WithVoice's settings (stored securely in your device Keychain). 2. Enable the WithVoice keyboard in Settings and allow microphone access. 3. Switch to the WithVoice keyboard, pick your language with the "ν•œ/A" key, tap the mic, and speak. 4. Your words appear as clean text at the cursor. PRIVACY FIRST WithVoice uses your own Gemini API key. Your recorded audio and the resulting text are sent only to Google's Gemini API to perform transcription and cleanup. WithVoice does not store your recordings, does not keep your transcripts, and includes no third-party analytics or tracking. See our Privacy Policy for full details. BUILT FOR iPHONE WithVoice is designed for iOS 26 and iPhone, with a fast, minimal keyboard and a single clear settings screen. No clutterβ€”just talk and type. NOTE: WithVoice requires your own Google Gemini API key, which you can obtain for free from Google AI Studio. Transcription is performed by Google's Gemini API and is subject to Google's terms and pricing for that service. An internet connection is required.
