Apps

Gmail

Search, organize, and respond to emails with simple commands. Genie reads your inbox, filters important messages, and drafts replies.

INKFLOW

Dictate, instruct, or transform — in any app.

InkFlow is NINX's system-wide writing layer. It works when NINX is in the background: global hotkeys, on-device Whisper STT, optional AI polish, and paste at your cursor.

Hold ⇧ Shift

Dictate

Speak in any app. On-device Whisper transcribes your voice and pastes polished text at the cursor — Notes, Slack, browsers, IDEs.

Hold Caps Lock

Instruct

Give a spoken command and InkFlow generates new text for you. Highlight a selection first to rewrite emails, docs, or code in place.

Dictate → Instruct

Transform

Chain modes: dictate first, then speak a transform command. InkFlow applies your instruction to the last dictation output.

INKFLOW HUD

A floating status chip appears at the bottom of your screen while recording or processing — even when NINX is not the frontmost app.

Whisper STT stays on-device; AI rewrite uses your active local or BYOK model.
Separate from chat voice — InkFlow writes into other apps, not the NINX window.
