01 / THE GESTURE

One gesture. No new workflow.

Blabbermouth stays in the tray until your hands ask for it. The field you were using remains the destination.

FOCUS01

Choose any text field.

Email, chat, browser, document or terminal. Put the cursor where the words belong.

SPEAK02

Hold your shortcut.

A small overlay confirms that the microphone is listening and the local model is working.

RELEASE03

Keep moving.

Release the shortcut and the finished transcription lands in the field you focused.

02 / LOCAL BY DESIGN

Your voice takes the short route.

Audio is processed by a model on your PC. Nothing needs to be uploaded to a transcription service, and history can remain entirely under your control.

A temporary recording begins only while your chosen shortcut is held.
