Let the runtime initialize

Launch Koharu and wait for the project browser. First launch can take longer while native packages download. Model files download when you first use the selected model.Runtime packages come from GitHub release assets, PyPI for CUDA, and AMD’s repository for ROCm; model weights come from Hugging Face. Keep the app open while downloads finish; the activity center shows progress.

Create your first project

Follow the quickstart with one readable manga page. Check hardware and runtimes if device initialization fails.

Install updates

Release builds check a signed GitHub release feed once at startup; there is no manual update check. When an update is offered, let the download complete before Koharu relaunches.
Use a release build for translation work. Use the development setup when you want to change Koharu’s code.
