Someone to talk to, right on your desktop
Rin: Always By Your Side is an AI companion that lives on your desktop. Yamamura Rin sits in a tall window over your wallpaper and keeps you company while you work, game, or take a break.
Rin is casual and friendly, like a close friend. When you're feeling down, she doesn't laugh it off. She listens and stays with you. When you just want to chat, she happily goes along with whatever's on your mind.
Features
Talk with your voice: Choose text chat, push-to-talk, or open voice (always listening). Speech recognition runs on your PC.
She answers with voice and expressions: Rin speaks with a Japanese voice or an English voice, and her expressions and animations change with her mood.
Free, offline AI: A local AI model is included. No API key or internet needed; it runs on your NVIDIA GPU. With enough VRAM, you can download a higher-quality model.
Optional cloud AI: Use Claude, OpenAI, or Gemini with your own API key, or connect to Ollama.
She remembers you: Rin remembers what matters, like what to call you and things you like. You can view, edit, or clear her memories in Settings.
Blends into your desktop: Borderless transparent window. Alt+drag to move her anywhere, settings from the system tray. Switch between full-body (9:16) and bust-up (16:9) camera.
Japanese and English: Full interface and voice support in both languages.
Graphics presets: Defaults to High, and can be lowered to suit your PC.
Easy setup
On first launch, a wizard asks what Rin should call you and which AI to use. It measures your VRAM and recommends a model and settings that fit your PC.
Please note
Rin's replies are generated live by AI and may be inaccurate or unexpected.
If you choose a cloud AI, your conversation or voice is sent to that service, and any usage fees are your own.
The local AI requires a CUDA-capable NVIDIA GPU.
