The idea
A little button. A lot less typing.
Promptly Mobile brings the same speak-to-text workflow to Android. A small floating button stays within reach over the app you're using: tap to record, tap again to stop, then paste the finished text from your clipboard. Colour changes communicate recording, transcription and a saved recording waiting for a connection.
Inside the product
Ready for your clipboard
Whisper transcription and optional text polish turn speech into clean text. Copy the result, then paste it wherever you need it.
Built around mobile
Quick settings tiles, a dismissible bubble and retries for connection failures keep the workflow convenient. Uses your own Groq API key.
How we built it
Built for Android 8.0 and later, the app sends audio to Groq’s Whisper API with the user’s own key. It retries temporary connection failures and copies finished text to the clipboard for manual pasting.
