YouTube Mode ​

When YouTube mode is enabled, comments can be retrieved from YouTube live streams, allowing AI characters to respond automatically.

Note

When YouTube mode is enabled, some features are automatically disabled.

YouTube API Settings ​

Settings for using the YouTube API.

YouTube API Key ​

Set the API key to use the YouTube API. To retrieve YouTube comments, you need an API key from Google Cloud Platform.

How to Get an API Key

  1. Access Google Cloud Platform, create an account or log in
  2. Create a project
  3. Enable "YouTube Data API v3" from "APIs & Services" > "Library"
  4. Generate an API key from "Credentials" > "Create Credentials" > "API Key"
  5. Enter the generated API key in this settings field

YouTube Live ID ​

Enter the ID of the YouTube live stream from which you want to retrieve comments. This value can be obtained from the URL of the YouTube live stream.

Example: If the YouTube URL is https://www.youtube.com/watch?v=abcdefghijk, the Live ID is abcdefghijk.

Note

The YouTube Live ID is the ID of a specific live stream, not a channel ID.

How to Use ​

When YouTube mode is enabled, a YouTube mode button appears in the upper left corner of the screen.

You can toggle comment retrieval on/off by clicking this button.

Comment Processing Mechanism ​

AITuber Kit processes YouTube comments in the following flow:

  1. Retrieve comments from the live stream using YouTube Data API v3 at set intervals
  2. Add retrieved comments to the processing queue
  3. Sequentially send comments in the queue to AI to generate responses
  4. Have the character speak the generated responses

Error Handling and Notes ​

  • Comment Retrieval Error: Comments may not be retrieved if the API key is invalid or has reached its limit
  • Rate Limit: YouTube Data API has usage limits, so you may reach the limit during long broadcasts
  • Comment Filtering: Comments starting with "#" are ignored
  • Resource Consumption: Memory usage may increase during long live streams

Conversation Continuation Mode (Beta) ​

A mode where AI continues the conversation on its own when there are no comments. Even if there are no comments for a while, the AI character will proactively develop the conversation.

About Beta Version

This Conversation Continuation Mode is currently provided as a beta version.

  • Specifications may change without notice
  • Operation may be unstable
  • Please thoroughly test before using in a production environment
  • We would appreciate your feedback if you discover any bugs or issues

Supported AI Services ​

Feature Details ​

In Conversation Continuation Mode, if there are no comments for a certain period of time, the AI refers to the past conversation context and provides new topics to maintain the natural flow of conversation.

Notes ​

About Usage Costs

  • Since LLM is called multiple times for a single response, API usage fees may increase

How to Use ​

You can toggle Conversation Continuation Mode on/off by clicking the "Conversation Continuation Mode" button when YouTube mode is enabled.
