The following picture demonstrates the effect after the subtitle file, which was generated through a one-click operation after importing a 46-minute local video, was inserted into the track. There was no manual adjustment involved at all. There are no missing or overlapping subtitles, the sentence segmentation is natural, and the translation quality is also quite high.

1. Download the executable file that matches your device system from the release and place it in an empty folder.
2. Create a config folder inside the folder, then create a config.toml file in the config folder. Copy the content from the config-example.toml file in the source code's config directory into config.toml and fill in your configuration information accordingly.
3. Double-click the executable file to start the service.
4. Open a browser and enter http://127.0.0.1:8888 to start using it (replace 8888 with the port you configured in the config.toml file).

This software is not signed, so after completing the file configuration in the "Basic Steps," you will need to manually trust the application on macOS. Follow these steps:

1. Open the terminal and navigate to the directory where the executable file (assuming the file name is KrillinAI_1.0.0_macOS_arm64) is located.
2. Execute the following commands in sequence:

sudo xattr -rd com.apple.quarantine ./KrillinAI_1.0.0_macOS_arm64
sudo chmod +x ./KrillinAI_1.0.0_macOS_arm64
./KrillinAI_1.0.0_macOS_arm64

This will start the service.

The quickest and most convenient configuration method:

• Select openai for both transcription_provider and llm_provider. In this way, you only need to fill in openai.apikey in the following three major configuration item categories, namely openai, local_model, and aliyun, and then you can conduct subtitle translation. (Fill in app.proxy, model and openai.base_url as per your own situation.)

The configuration method for using the local speech recognition model (macOS is not supported for the time being) (a choice that takes into account cost, speed, and quality):

• Fill in fasterwhisper for transcription_provider and openai for llm_provider. In this way, you only need to fill in openai.apikey and local_model.faster_whisper in the following three major configuration item categories, namely openai and local_model, and then you can conduct subtitle translation. The local model will be downloaded automatically. (The same applies to app.proxy and openai.base_url as mentioned above.)

The following usage situations require the configuration of Alibaba Cloud:

• If llm_provider is filled with aliyun, it indicates that the large model service of Alibaba Cloud will be used. Consequently, the configuration of the aliyun.bailian item needs to be set up.
• If transcription_provider is filled with aliyun, or if the "voice dubbing" function is enabled when starting a task, the voice service of Alibaba Cloud will be utilized. Therefore, the configuration of the aliyun.speech item needs to be filled in.
• If the "voice dubbing" function is enabled and local audio files are uploaded for voice timbre cloning at the same time, the OSS cloud storage service of Alibaba Cloud will also be used. Hence, the configuration of the aliyun.oss item needs to be filled in. Configuration Guide: Alibaba Cloud Configuration Instructions
