Caption Translator

# What is Caption Trans? Use AI large language models to translate video subtitles. **Especially optimized for Japanese.** Supports: Google Gemini, OpenAI, DeepSeek, and other OpenAI-compatible API services. # Download Supports macOS (Apple Silicon) and Windows. Please go to [Releases](https://github.com/cddqssc/Caption-Trans/releases) to download. ## ⚠️ How to open on macOS 1. Double-click the app. Since it is not currently signed with an Apple developer certificate, it will be blocked by the system. 2. Go to **System Settings** > **Privacy & Security**. 3. Scroll down and find the blocked app notice in the Security section, then click **"Open Anyway"**. 4. After verifying your Mac password, click **"Open"** in the final popup. *(You only need to do this once. After that, you can open it normally by double-clicking.)* # App Screenshots

# GPU Acceleration macOS (Apple Silicon) automatically supports GPU acceleration. Windows users with NVIDIA graphics cards automatically have GPU acceleration support. # Notes Transcription is especially optimized for Japanese, and GPU acceleration is supported on both Windows and macOS. For translation, I recommend the **gemini flash lite** model. In practice, it is very fast, delivers solid quality, and is relatively affordable. It can also translate some sensitive content. # License [MIT License](LICENSE)
