Install Release Builds

Normal users should start from Release builds. Local compilation is not required.

Download Entry

Open Neiroha Releases and choose the latest version. The current latest version is v0.3.1, released on 2026-05-30.

Release builds are produced and published by GitHub Actions in the main application repository. You do not need Flutter or local build commands when using these packages.

Windows

1. Download neiroha-v0.3.1-windows-x64-release.zip.
2. Extract it to a stable directory, such as a dedicated Neiroha folder for portable apps.
3. Run neiroha.exe.
4. If Windows SmartScreen warns about an unknown publisher, continue only after confirming the file came from the official Release page.
5. After first launch, follow the provider setup steps in Quick Start.

Android

1. Download neiroha-v0.3.1-android-release.apk.
2. Copy the APK to the Android device.
3. Enable installing apps from unknown sources in system settings.
4. Install the APK and launch Neiroha.
5. Android supports the UI and TTS client workflows. Local FFmpeg muxing, trimming, waveform extraction, and video export are currently disabled.

Linux x64

1. Download neiroha-v0.3.1-linux-x64-release.tar.gz.
2. Extract it to a stable directory.
3. Run the Neiroha executable in the extracted bundle.
4. For video dubbing export, make sure FFmpeg is installed and configured or detected in Settings -> Media Tools.

Verify Files

The Release page no longer provides separate SHA256SUMS*.txt files. Checksums are written directly in the Release body under Checksums, and GitHub asset metadata also shows digests.

Current v0.3.1 checksums:

File	SHA256
neiroha-v0.3.1-windows-x64-release.zip	baaa0c97a73e43b90e61ec651c0e24b961fce1548e918d916d594565e0a68a4f
neiroha-v0.3.1-android-release.apk	e722f82614007f07c7e06384705e6790d71cee396176a2d3ef3672c50c012160
neiroha-v0.3.1-linux-x64-release.tar.gz	da2cfafaadee63aad7c3b91afeec5ff09d6047bbba450718af32517f967ce660

Windows PowerShell example:

Get-FileHash .\neiroha-v0.3.1-windows-x64-release.zip -Algorithm SHA256

Android and Linux packages can be checked the same way on Windows, or with sha256sum on systems that provide it.

Local Backend Portable Packages

Local large-model TTS backends are downloaded separately. The main Neiroha Release only contains the Neiroha client and does not include GPT-SoVITS, VoxCPM2, or CosyVoice3 models.

The Windows portable backend packages are built for NVIDIA GPU / CUDA environments and mainly target RTX 30 / 40 / 50 series users. They are unzip-and-run packages. If GitHub Release downloads are unstable, use the Baidu Netdisk mirrors listed in the Release body.

Backend	Release Page	Baidu Netdisk Mirror	Download Pattern
GPT-SoVITS	Neiroha-GPT-SoVITS V1.0.0	Mirror	Download Neiroha-GPT-SoVITS-Portable.7z.001 through .003, then extract from .001.
VoxCPM2	Neiroha-VoxCPM V1.0.0	Mirror	Download Neiroha-VoxCPM-portable.7z.001 through .004, then extract from .001.
CosyVoice3	Neiroha-Cosyvoice V1.0.0	Mirror	Download neiroha-cosyvoice3-portable.7z.001 through .006, then extract from .001.

All split archive parts must stay in the same directory. Downloading only .001 or moving a single part separately cannot produce a complete extraction.

Update Versions

Download the new Release build and replace the old program directory. Neiroha data and generated audio are stored in the system application data directory by default, not inside the program directory.

If you use a Windows portable release that stores portable data in the program directory, keep a backup before replacing the directory.
