Automated YouTube Transcription, Summarization & Translation Workflow

This n8n workflow automates the process of transcribing a YouTube video, summarizing its content, translating it into a selected language, and saving the results in a Google Document. The process begins with a webhook trigger that accepts a YouTube URL, target language, and an option to enable summarization. The workflow extracts the video ID from the URL, requests the transcription from an external API, and merges the segmented transcription into one coherent text. The merged transcript is then processed by Google’s language model to generate a translation and a concise summary in the target language. A new Google Document is created with a title based on the video ID and language, and the translated summary is appended to this document. This workflow is useful for content creators, researchers, or educators who need quick, automated access to translated summaries of YouTube videos for documentation or review purposes.
