Automated YouTube Video Transcript Summarization to Google Docs

This n8n workflow automates the process of summarizing YouTube video transcripts for social media or documentation purposes. It begins with a user submitting a form containing the YouTube video URL and desired language. The workflow then fetches the transcript using an API, formats and decodes it, and passes it to an AI model (Google Gemini PaLM) to generate a concise summary in the chosen language. The resulting summary is extracted and inserted into a Google Doc for easy sharing or editing. This automation is ideal for content creators, social media managers, or teams who want quick, accurate summaries of video content without manual effort.

### Workflow Steps:

1. **Form Submission** – Collects the video URL and language preference.

2. **Data Mapping** – Assigns form inputs to variables for processing.

3. **Transcript Retrieval** – Sends a POST request to the YouTube transcript API to fetch the transcript.

4. **Transcript Formatting** – Decodes Unicode characters, cleans, and verifies the transcript data.

5. **AI Summarization** – Uses Google Gemini PaLM model to generate a short, relevant summary in the specified language.

6. **Summary Extraction** – Parses and extracts the concise summary from the AI output.

7. **Google Docs Update** – Inserts the summary into a predefined Google Document.
