Made for Booth creators & VRM commissions
Bring your character to life and showcase it as a live desktop presence.
RealWaifu is a VRM desktop avatar companion made for creators: use your Booth VRM model or a commissioned VRM avatar and showcase it as a live screen pet on your desktop. Features include voice chat, real-time lip sync, memory, and an always-on-top transparent overlay.
If you’re into the “AI girlfriend / AI companion” experience — this is that category, but with a real 3D avatar and voice. You control the character, the vibe, and the boundaries.
Compatibility note: VRM (.vrm) format only. Many avatar tools export VRM; VRoid Studio exports are typically VRM as well.
