WHAT IT CAN DO
Things you can say.
Wake it with "chappie", then just keep talking.
Aurora & space weather
- "Can I see the aurora tonight?"
- "Any geomagnetic storm?"
- "What's the aurora forecast?"
From NOAA's space-weather data, an honest read on whether the aurora might be visible — based on geomagnetic activity (the Kp index) and your latitude.
Control your music
- "Next track"
- "Pause for a sec"
- "What song is this?"
Voice control for whichever of Spotify or Apple Music is already running. Play / pause / skip, plus "what song is this?" gets you the title and artist.
Read the latest news
- "What's the latest news?"
- "Any world news?"
- "Read me Nintendo news."
Top headlines, tech, and world feeds plus on-the-fly topic search — just say what you want to hear about. If nothing comes back, Chappie opens the search in your browser. Voice-only morning briefing.
A masterpiece as wallpaper
- "Set a famous painting as my wallpaper"
- "Make a Van Gogh my wallpaper"
- "Use a Japanese woodblock print"
A public-domain masterpiece from the Art Institute of Chicago becomes your desktop wallpaper. Name an artist or style, or leave it up to chance for a fresh piece — with a word on what it is.

LIVES IN THE MENU BAR
Always tucked into the menu bar.
Shows up only when you need it.
No Dock icon, no window. Stays quietly in standby until you call.
An assistant that blends into your day
Just the right distance — visible when needed, invisible when not.
Just say "chappie"
No hotkeys, no clicks. Wake it with your voice, then keep talking naturally.
Only responds to your voice
Enroll your voice once and Chappie tunes out the TV, YouTube, and other people around you. Your voiceprint stays on your device.
Voice stays local
Speech is transcribed entirely on your device.
Remembers what matters
What you were just saying continues naturally. Names, family, preferences — the things that stick — quietly carry across sessions.
Conversations that grow over time (experimental)
Remembers the flow of your everyday conversations and brings up things you mentioned a few days ago in a natural way.
Speaks up when it matters — no need to ask
A morning heads-up, a nudge just before your next event, a sudden turn in the weather — Chappie can reach out on its own. You choose whether it speaks aloud or just shows on screen.
Weather for your town, not the nearest big city
Uses macOS Location Services to ground weather and "nearby" questions in your actual area. If you decline the permission, Chappie falls back to a rough location estimate — so it works either way.
Menu bar resident, no Dock clutter
The app is just a menu bar icon. Settings open only when you need them.
Speaks 9 languages
Japanese and English are stable. Spanish, French, German, Italian, Portuguese, Korean, and Simplified Chinese are in Beta. Pick one and Chappie automatically uses a matching macOS system voice.
Auto-update
Checks at launch and quietly every 6 hours. New versions show a tray badge so you can update on your time.
THREE EXPRESSIONS
Status shows on Chappie's face in the menu bar.
Waiting quietly for you to say "chappie".
Tuned in and capturing what you're saying.
Reading the reply out loud.
Your voice stays on your device
What the mic picks up is converted to text right on your device. The recording itself never goes to the internet. Only the text version of your question is sent to an AI service to think up a reply.
Try saying hello.
Download, then look at the Chappie icon in your menu bar and say "chappie".
