Yes you can train your AI tools by adding youtube videos. It’s fairly simple, though not explicitly spelled out how to do it.
To add a youtube videos to the knowledge base of a tool, in the no-code chatbot builder go to the “Knowledge Base” section, click “Add Website” and paste a youtube link there.
The youtube video’s transcript will be scraped and add to the knowledge base of your tool. Importantly, it will not know the visual contents of the video unless that is reflected in the transcript.
