TinyRoommate

An AI pet that lives on your desktop.

---

You open the app. A small cat appears on your desktop. It walks around, sits down, yawns.

Every few minutes, a speech bubble pops up — sometimes random ("~♪"), sometimes surprisingly relevant ("you've been coding since 9am... take a break?"). You can pet it, talk to it, or just let it be.

A little friend that lives in the corner of your screen.
Long hours feel shorter when you're not alone.

It sees what you see Screen capture + Claude Vision — knows if you're coding, designing, or doom-scrolling. It remembers you A living memory that grows over time. Not a stateless chatbot. It has personality Sassy, chill, philosophical — you configure it. Knows when to shut up.

It has feelings Pet it → purrs. Ignore it → it gets a little sad. It notices when you're around. It keeps a diary Plain Markdown files — its journal, what it saw on your screen, daily summaries. You can read them. 100% local All data stays on your machine. Nothing leaves your laptop.

Characters

Pick a companion — or make your own.

                   

_{Tabby Cat · Golden Retriever · Blue Buddy · Schnauzer · Coco}

Each character has its own animations and voice lines. Want something different? Generate a spritesheet with any AI image tool (Gemini, Midjourney, etc.), drop it in, and it just works. See the Sprite Spec for details.

To add a new pet like Coco, the repo convention is:

python3 -m pip install --user pillow numpy
python3 scripts/process-spritesheet-v4.py path/to/coco-source.png \
  -o public/sprites/coco.png \
  --cols 8 --rows 9 --target 128
python3 scripts/generate-preview-gif.py public/sprites/coco.png \
  -o assets/previews/coco.gif \
  --still-output assets/previews/coco.png

Then register coco in src/characters.js. The Settings picker is generated from that file automatically.

A Day in Its Life

Your pet reacts to what's happening — not randomly, but contextually.

You're deep in code It works alongside you	You switch apps It notices and observes	You're watching YouTube It starts playing around
It's past midnight "you should rest..." 💤	You pet it Affection +1, purrs	You've been away Hearts decay over time
Nothing happening It wanders your desktop	You drag it Swing physics, not amused	Just vibing Silence is often the right choice

Quick Start

Note: TinyRoommate currently runs on macOS only. Windows and Linux support is on the roadmap.

You need Node.js (v18+), Rust, and Claude Code (for the AI brain).

gh repo fork ryannli/tinyroommate --clone
cd tinyroommate
npm install
npx tauri dev

Prerequisites

• Node.js v18+
• Rust
• Claude Code — for the AI brain (optional — pet still runs without it, just can't think or talk)

Screen Recording permission (optional)

For the pet to "see" your screen: System Settings → Privacy & Security → Screen Recording → enable your terminal app → restart terminal.

Without this, everything still works — it just can't see what you're doing.

Linux dependencies

sudo apt-get install -y \
  pkg-config libgtk-3-dev libwebkit2gtk-4.1-dev \
  libayatana-appindicator3-dev librsvg2-dev libssl-dev \
  fonts-noto-color-emoji

First launch compiles Rust (~2-3 min). After that it's instant.
