HoloWaifu: Your AI Girlfriend
Lives on your Desktop.

Turn any VRM avatar into a living desktop mascot and virtual assistant. Talk by voice, get real-time lip-sync, and build a relationship with long-term memory - an always-on-top presence, not just a chatbot.

Beyond the Chat Window

Most "AI girlfriends" are locked in a browser tab or a mobile app. HoloWaifu breaks that wall. She stays with you as a transparent overlay on top of your windows, games, or code. Not just another chatbot with a pretty face - a companion that shares your world. Keep doing your thing while she reacts to your voice and keeps you company.

  • Always-on-top transparent overlay
  • Stays visible while you work, play, or code
  • Optional click-through mode (stay focused)

She Remembers. She Understands. She Speaks.

Forget bots that forget your name after five minutes.

  • Deep long-term memory (RAG) that grows with you
  • Natural voice replies with real-time lip-sync
  • From friendly support to a virtual girlfriend experience - you set the tone

Your Waifu. Your Choice. Endless Customization.

Have a favorite model from VRoid Studio? Bought an amazing avatar on Booth? HoloWaifu is the perfect desktop player for your characters.

  • Full VRM support - import any .vrm in seconds
  • VTuber-grade models on your desktop, not just on stream
  • Scale and place her anywhere: shoulder, taskbar, or full height

Privacy. Freedom. No Filters.

HoloWaifu runs locally on your PC, so your conversations stay between you two - a private space where you can be yourself.

  • Local-first by design: your chats stay on your device
  • Unfiltered AI (optional): talk about anything
  • Waifu simulator: from innocent flirting to something more (18+ mode planned)
