Subtle is the companion app for Subtle Voicebuds — a device that hears only you, even at your quietest. Subtle combines dictation, voice notes, and AI chat for a complete voice-first computing experience, letting you run your day with voice. WRITE WITH A WHISPER, IN ANY APP The Subtle keyboard turns your speech into text wherever you type — messages, email, notes, search, no app-switching required. Tap the mic, speak aloud or whisper, and see your words appear. Because the Voicebuds are tuned for your quiet voice, dictation works in a noisy café or a silent library without raising your voice. CAPTURE NOTES AS YOU THINK Record a thought the moment it arrives. Your recordings are transcribed into notes you can search, edit, and organize. Your notes and chats are encrypted in transit and at rest. BUILT FOR LOUD AND QUIET SPACES Traditional earbuds were built for listening. Subtle Voicebuds are built for speaking. The Subtle Voice Engine hears you and nothing else, even in loud environments where voice traditionally fails. Whisper-level dictation means your voice still gets through, even when speaking aloud isn’t an option. The Subtle app requires Voicebuds at this time. Pair your Voicebuds in the app to get started.
