An actual-use example, not a fixed rate. Your cost depends on the provider, model, and token usage.

A few steps.
Then, the next chapter.

A few things before you begin.

What do I need to run it?

A Windows 10 version 2004 or later (build 19041+) or Windows 11 PC with x64 support. The installer includes the .NET 10 runtime and OCR models. Dictionaries are prepared during onboarding.

Do I need an AI subscription?

AI explanations and translations use the provider and API key you configure. A ChatGPT or Claude chat subscription does not automatically include API usage. Costs are determined by your chosen provider.

Can I use my own explanation language?

Yes. Choose a left-to-right language supported by your model. This is independent of the app interface, which is available in English and Simplified Chinese.

Where can I see the source or report an issue?

The project, release notes, and issue tracker are on GitHub. The links below take you straight there.
