Virmii is a browser-based AI VTuber maker that converts a single 2D character image into a rigged 3D avatar, adds AI-generated facial expressions, and drives it with webcam face tracking for live streaming through OBS.
What is Virmii?
Virmii takes one uploaded character image and produces a 3D humanoid avatar with an optional AI expression set, usable in Virmii's own Live Studio or as a private OBS Browser Source. The base 3D model generation and automatic humanoid rigging come from a third-party service, Tripo; Virmii handles model processing, VRM export, AI expression features, browser face tracking and OBS integration. Everything runs in the browser, and the studio is reached at virmii.com/studio. The page also offers a no-sign-up showcase of real avatars and a demo page with a YouTube walkthrough.
Key Features
- Image to 3D — upload one character image (ideally clear, front-facing and full-body) and Virmii prepares it for 3D; Tripo supplies base generation and automatic humanoid rigging, Virmii does the processing.
- AI expression sets — generate Neutral, Wink, Smile and Speak expressions from the finished model, priced at 20 credits per set or covered by an included Creator or Pro monthly generation.
- Retry allowance — each model version includes up to 2 free retries for missing or failed images.
- Browser face tracking — a webcam drives the avatar's expressions in real time with no extra software installed.
- Private OBS Browser Source — the avatar is added as a source inside OBS Studio next to existing scenes, game capture and mic sources.
- VRM export — models can be downloaded as VRM files for use in other VRM-compatible applications.
- Model versioning — the current generation model is labeled Virmii Model v1.
Who should use Virmii?
- First-time VTubers: turn an existing character drawing into a streamable avatar without any modeling or rigging background.
- OBS streamers: drop a face-tracked avatar into an existing OBS scene as a Browser Source for Just Chatting, gameplay or BRB screens.
- Illustrators and OC owners: give an original character a 3D form and a small expression library (neutral, wink, smile, speaking mouth) for shorts and streams.
- Curious creators evaluating tools: browse the showcase of real avatars with no sign-up before spending credits on a generation.
Use cases
- Just Chatting streamers: add a cat-eared avatar over a fantasy background scene in OBS, with the mouth moving from live face tracking while talking to chat.
- Character artists: upload a full-body reference of an original character and get a rigged 3D version for a debut stream.
- Creators testing before committing: open the no-sign-up showcase or demo page to judge generation quality on fox-eared and cat-eared sample characters first.
How does Virmii work?
- Upload a character image in the studio; Virmii prepares it for 3D.
- Generate the model, then add AI expressions using credits or your subscription allowance.
- Add the avatar as a Browser Source in OBS and go live.
Virmii states plainly that AI generation may change the character's face, clothing, proportions and details, and an exact match to the reference is not guaranteed.
Pricing
Virmii runs on a credit and subscription model with a freemium entry point: browsing real avatars requires no sign-up, and each model version includes up to 2 free retries for missing or failed images. Expression sets cost 20 credits without a subscription; the Creator and Pro tiers use included monthly generations first and then 20 credits per set. Completed expressions stay usable after a subscription ends.
Alternatives
- VRoid Studio — dedicated to building VRM avatars through manual 3D modeling rather than image generation.
- VTube Studio — a desktop app for running and face-tracking Live2D models.
FAQ
Can I use my own character image?
Yes, as long as you own it or have permission to use it. A clear, front-facing image with the full body visible gives the best 3D starting point; the page warns that AI generation may still alter the face, clothing, proportions and details.
Will my avatar match my reference exactly?
No. Virmii says AI generation may change the character's face, clothing, proportions and details, each new generation spends credits, and more attempts do not guarantee a closer match. If a result differs significantly or is unusable, the page asks you to email [email protected] before generating again.
Do I need modeling experience?
No modeling experience is needed. The workflow is upload an image, generate the model, then follow the studio steps to add expressions and set up browser face tracking.
Where do AI expressions work?
AI expressions play in Virmii's live studio and in its OBS Browser Source. They are not included in downloaded VRM files, so other VRM applications need their own supported expression setup, which may require additional configuration outside Virmii.
