What it does
An OBS plugin that transcribes what you say and puts it on screen as you speak, with optional translation for viewers in other languages. Processing happens locally so no audio is sent anywhere. It competes with the stream for CPU, so test the load before going live, and real-time transcription is less accurate than offline - mishearings go straight onto the screen, and Japanese is weaker than English.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
