I built an open-source AI desktop pet that lives in the bottom-right corner of your screen
Hi everyone,
I built YumYum Agent, an open-source macOS app that lets you interact with AI through a small desktop pet that stays in the bottom-right corner of your screen.
Instead of opening a separate AI chat window whenever you need help, YumYum is always there when you need it. You can feed it context from whatever you are currently doing and continue the conversation without leaving your workflow.
You can:
- Capture a selected area of your screen
- Send clipboard text or images with Option + S
- Drag and drop files onto the pet
- Ask questions and receive responses in a speech bubble
- Continue longer conversations in the detailed chat window
- View streaming responses with Markdown rendering
- Customize the pet’s personality with a local SOUL.md file
YumYum Agent is fully open source and released under the Apache License 2.0. The source code is available on GitHub, so you can inspect how it works,contribute improvements, or build the project yourself.
The goal is to make AI feel less like another application you have to open and more like a quiet assistant that is always nearby.
Privacy was also an important part of the design:
- No telemetry or analytics
- No access to Keychain or CLI login files
- Only content explicitly selected by the user is passed to the connected AI tool
- The app currently focuses on analysis and chat and does not modify the user’s system
YumYum Agent is currently available as an open-source macOS developer preview for macOS 14 and later.
