Feed it your screen,
keep the conversation going.

Feed a screen capture or a file to the pet on your desktop, and it hands them to the local AI CLI you are already signed in to — answers come back in a native speech bubble and chat.

How it works

Feeding takes a second.
The conversation keeps going.

Keep what you hand the pet simple. Answers continue across multiple turns.

01RIGHT CLICK

Capture

Right-click the pet, pick a screen region, and it is sent right away.

02OPTION + S

Feed the clipboard

Left-click, or press the default global shortcut Option+S, to put clipboard content — file, then image, then text — into the chat draft.

03DRAG & DROP

Drop a file

Drag a file from Finder onto the pet, or attach it from the file picker.

04NATIVE CHAT

Answer UI

A scrolling conversation stacks up across turns and survives closing and reopening. The detail chat window renders streaming Markdown.

Clipboard: It lands in the draft; you press Return to actually send. Nothing is sent automatically.Permissions: Accessibility + Input Monitoring · Screen Recording

Quicker to watch
than to read about.

Supported agents

Sign in separately,
chat in one place.

YumYum Agent does not handle installing or signing in. It connects to the local CLIs you set up yourself.

plan permission mode

You install and sign in to each CLI separately. Names and trademarks are used only to describe compatibility and do not imply sponsorship or endorsement.

Privacy

You decide
what gets fed.

01 / no telemetry

What it never sends

It sends no telemetry and never reads your Keychain or CLI login files.

02 / selected only

Only what you pick

Only the text, files, and captures you explicitly choose are passed to the CLI you selected.

03 / soul.md

The character personality stays local

Stored in plain text at ~/Library/Application Support/YumYum/SOUL.md, injected only into the first prompt of a new session.

Right now it is analysis and chat only. The agent has no ability to make actual changes to your system.
