Features

Built around how you actually use a Mac.

Push-to-talk

Hold Ctrl + Option anywhere on your Mac to ask Buddy. No wake word, no chat window to open.

Screen-aware

Buddy captures the display your cursor is on and grounds every answer in what you’re actually looking at.

Draggable answer

Answers land in a floating, draggable window that stays until you close it. Copy, read, reference. Never auto-dismissed.

Warm voice

Spoken summaries use gpt-4o-mini-tts with a steerable style: calm pacing, natural pauses, a friend next to you.

Local key storage

Your OpenAI API key is kept in the macOS Keychain. No server, no sign-up, no relay.

Low latency

MP3 TTS and a short spoken contract keep first-audio-byte fast, so it feels like a conversation, not a wait.

How it works

Three gestures. That’s the whole product.

01

Hold

Press and hold Ctrl + Option anywhere. Buddy shows a small cue near your cursor while it listens.

02

Ask

Speak your question naturally. On release, Buddy snaps a screenshot of the display you’re looking at.

03

Answer

A draggable answer window appears with the full markdown answer. A warm, short spoken summary plays.
