04Questions

Is MouthPiece free?

Yes. The free tier gives you unlimited recording, live transcription, and instant cleanup that runs entirely in your browser — no account, no card. Pro ($6/month) adds AI transcription and AI cleanup for higher-quality results.

Does my audio get uploaded?

Never. Your audio stays on your device and is never stored. On the free tier, cleanup happens entirely in your browser. On Pro, only the text you dictated is sent for AI polishing — never the audio, and it is not kept.

What is the difference between Free and Pro?

Free uses your browser's built-in speech recognition and rule-based cleanup that removes filler words and fixes punctuation. Pro adds Whisper transcription (accurate even in noise) and Claude-powered cleanup that genuinely rephrases rambling speech into publish-ready text.

Do I need an account?

No. MouthPiece has no login. Cross-device sync and Pro access both work through a private key stored on your device, not an email and password.

What tones can it write in?

Six: Auto, Email, Message, Formal, Notes, and Comment. The cleanup pass rewrites your speech for wherever it's headed.

Is there a Mac app?

Yes. The MouthPiece Mac app lets you hold Option+Space in any application — speech is transcribed, cleaned up, and pasted right where you're typing.
