Amethyst

A tiny, always-on-top companion that lives on your Windows desktop — draggable, click-through, and one shortcut away from help.

Pre-release build

  • 110 × 120 pixels — a small transparent window holding a single character, floating above your other applications. Grab the character itself and the whole window follows your cursor, natively, with no lag.
  • Click-through by default. Opaque pixels of the character accept the mouse; transparent padding passes every click straight to whatever app is underneath.
  • Ctrl+Shift+Space toggles Amethyst from anywhere in Windows — and your last position is remembered on this device.

The pill

What you can do from the pill

Hover Amethyst and a compact pill expands with three actions. Each one opens a focused mode docked right under the character.

  • Look at my screen

    Type a question, press Send, and one fresh screenshot of the display your cursor is on is captured for that answer.

    Screen awareness
  • Text chat

    A compact input that streams replies from the same conversation as the main window.

    Documentation
  • Voice chat

    Hold the mic, speak, release; the transcript becomes the question and the reply is spoken back.

    Voice interaction

Sessions

One session, one conversation

The moment Amethyst appears, a session begins. The first send lazily creates exactly one conversation — titled from your first message — and every text, voice and screen question in that session joins it. Hiding Amethyst ends the session; showing it again starts a fresh one. Nothing is created until you actually send something.

  • 110×120pixel companion window — small enough to ignore
  • 3pill actions: screen, text and voice
  • 60smaximum voice recording per press
  • 1conversation created per session, on first send

Show it, hide it, keep it

  • Ctrl+Shift+Space toggles Amethyst from anywhere in Windows.
  • The sidebar row DOT Mini shows and hides it, with the live status dot.
  • Your last position is remembered on this device and restored on launch when it is still on a connected display.
  • Turning it off at quit keeps it off at the next launch.
  • Drag settle, hide, and quit all restore the click-through state automatically.

Everything above describes the current pre-release build. The first public build (v0.1.0) is available on the download page.

What Amethyst does not do

Honest boundaries matter more than feature lists:

  • Never captures in the background. Capture happens only when you press Send on a screen question.
  • Never clicks, types, or moves your mouse. Guidance is drawn on a transparent overlay — your hands stay on the controls. AI transparency
  • Never listens for a wake word. The mic opens only while you hold the voice button, up to 60 seconds.
  • Never lingers in the taskbar. Hiding it removes the window entirely until you ask for it again.
