2Set up your workspace
Install the app on web if a native client is available, or simply open it in your browser. Configure basic preferences such as language, notifications, and default output style so that subsequent runs feel consistent.
3Run your first task with High-accuracy AI translation (TOEIC 960 level)
Start with a small, low-stakes task to understand how みらい翻訳 responds. Write a clear prompt or input, review the output, and iterate. This low-risk exploration is the fastest way to build intuition for what the tool excels at.
