How It Works

Three moves.
Total control.

No setup. No configuration. No training. Hold, speak, and watch. That's it.

Hold

Hold down one key. That's it. Steward starts listening instantly. The floating HUD appears, waveform active, ready for your voice.

2

Speak

Why Steward

Not another assistant.
A different approach.

Siri can't control your apps. Shortcuts take hours to build. AI agents need the cloud. Steward gives you real control, with your voice, on your machine.
