Download the Windows x64 app for free (about 731 MB). Creating a new character requires one separately purchased ¥3,980 creation ticket. Check the pricing page for purchase availability.

Run the installer and follow its instructions. The Windows publisher signature has not yet been obtained. Verify that the file came from this official website. Updates preserve existing projects.

Download

Prepare in the cloud. Stream from your PC.

Image generation and character finishing run in the cloud. Uploading, requesting production and receiving results require an internet connection.

Create in the cloud

Sign in with a valid production ticket to generate images and prepare backgrounds, expressions and direction assets.

Display and stream on your PC

Character rendering, camera recognition, OBS and games run on your PC. This is not a service that continuously streams your rendered video from the cloud.

Minimum and recommended specifications are still being measured. Even with cloud preparation, games, OBS and output size affect PC load. Smooth operation on low-end PCs and GPU-free operation are not guaranteed.

More: screen labels and differences from earlier versions

Completed characters are saved in your private cloud library. Check progress in the app and resume from saved stages. Timing varies with connectivity and provider availability.

System requirements

Operating system
Windows x64. Tested on Windows; the official supported version range is still under review.
Display
The adopted build has an 800×540 minimum window and opens at 1280×800. Allow at least 1280×800 of workspace after OS display scaling as a usability guideline. The minimum window size is not a comfort recommendation.
Runtime
Microsoft Edge WebView2 Runtime is required. Get the Windows x64 installer using the button above.
Camera
Windows-compatible built-in or USB camera. Real-face tracking, reacquisition, minimized operation and simultaneous OBS use need final hardware checks on this candidate.
Streaming software
OBS Studio browser source. The earlier OBS 32.2.2 test on 0.5.0 does not establish simultaneous operation with the current candidate.
CPU, memory & storage
Minimum and recommended specifications are still being measured. Even with cloud preparation, games, OBS and output size affect PC load. Smooth operation on low-end PCs and GPU-free operation are not guaranteed.

Checked on:

Model compatibility and video output to OBS are different

Current character and rendering data are app-specific. Direct use in other software and VRM/Live2D export are unsupported. .aster is the previous editor’s project format, not a complete backup format for the new UI.

OBS can display video through a browser source. This does not transfer a model. Permission to stream or commercially use that video depends on the asset rights and final usage terms. The format limitation alone does not prohibit lawful uses of your own original assets elsewhere.

Current limitations

  • macOS, Linux and iPhone are outside the current scope.
  • Choose a sample to check head direction, blinking and mouth movement. The appearance of expressions is still being refined.
  • Image generation and cloud finishing require login, a valid creation ticket and an internet connection. See the pricing page for purchase availability.
