# Virmii

> Virmii is a browser-based AI VTuber avatar studio for creating, managing, downloading, and driving 3D avatars. It combines reference-image-based avatar generation, VRM model management, browser face tracking, and OBS output for new VTubers and independent creators.

Virmii supports AI avatar generation from either a character reference image or a text description. In Text mode, no reference image is required. Virmii supports AI expression generation for models created in Virmii: 13 expression images for blinking, smiling, and mouth movement, played through camera tracking in Virmii previews, Live Studio, and OBS. Uploaded VRMs use their existing expression bindings; generated expression artwork is not embedded in VRM downloads. Users may also upload compatible VRM models to a private model library.

Virmii offers Free, Creator ($15/month), and Pro ($29.99/month), plus one-time credit packs. Paid plans include monthly credits and larger model allowances. Prices are in USD excluding tax. The current avatar creation cost is shown in Virmii before generation. Completed outputs are delivered digitally through the user's account and may include downloadable VRM and GLB files. Raw camera video used for face tracking is processed locally in the browser by default.

AI expression generation costs 20 credits per expression set without a subscription. Creator includes 3 generations per monthly billing cycle; Pro includes 6. These allowances are separate from monthly credits, reset each paid billing cycle, and do not roll over. Additional subscriber sets cost 20 credits. The initial charge is kept if generation fails. Each model version allows up to 2 free retries for missing or failed images, without using additional credits, included generations, or model retry attempts. Existing completed expressions remain usable after a subscription ends.
