YouTube Transcription, Summary & Translation to Google Docs with Gemini AI

This n8n workflow streamlines the conversion of YouTube videos into structured, multilingual documents. Triggered by a webhook with a YouTube URL, target language, and summary option, it extracts the video ID, fetches a full transcription via Supadata API, combines segments into coherent text, and uses Google Gemini AI to summarize and translate as needed. The result is appended to a new Google Doc titled with the video ID and language, ready for review or sharing.

Key benefits include massive time savings for content creators, educators, marketers, and students by automating tedious manual transcription and localization. It supports international audiences by translating lectures, fitness videos, or tutorials into preferred languages, while optional summarization provides concise notes. Integrations with premium services like Gemini Vertex AI and Google Docs ensure high-quality, professional outputs without coding expertise.

Use cases span lifestyle and fitness niches: fitness influencers transcribing workout videos into multilingual guides; educators translating study lectures; bloggers repurposing content for global reach. Setup is straightforward—configure webhook inputs, Supadata credentials, Gemini model, and Google Docs access—for instant automation of video-to-text workflows.
