Are you tired of manually transcribing and formatting your YouTube videos into blog posts? Imagine a tool that does it all for you—saving time while boosting your online presence. Meet GEN-BLOG, a Node.js-powered solution I’ve built to transform YouTube transcripts into polished, SEO-friendly blog posts using Google’s Gemini AI model. In this post, I’ll walk you through how it works, its key features, and why it’s a must-have for content creators and developers. Plus, stick around for a link to see it in action!

What Does GEN-BLOG Do?

GEN-BLOG simplifies content repurposing with a few powerful steps:

  • Extracts Transcripts: It pulls the transcript from any YouTube video using the youtube-transcript package.
  • Generates Blog Posts: Powered by Gemini AI, it turns raw transcripts into structured Markdown files with front matter, ready for platforms like VuePress or Gatsby.
  • Creates JSON Metadata: It produces a JSON object for your blog homepage, complete with titles, links, and summaries.

This automation cuts hours from your workflow, letting you focus on creating more content instead of formatting it.

How GEN-BLOG Works

Let’s break down the process into digestible parts:

Project Setup

The GEN-BLOG directory is clean and user-friendly:

  • index.js: The heart of the tool, housing the ContentGenerator class.
  • example.js: A sample script to get you started.
  • prompts folder: Holds templates like blog.txt to guide the AI’s output.
  • output folder: Stores your generated blog posts, named with video IDs and dates (e.g., blog-9NOB57SCCeQ-2025-05-22.md).

This structure makes it easy to jump in and start generating content.

The Code Behind It

The ContentGenerator class drives GEN-BLOG’s magic:

  • Setup: Initializes API connections (OpenAI and Gemini) using keys from a .env file.
  • Transcript Fetching: Extracts the video ID from a URL and grabs the transcript.
  • AI Processing: Sends the transcript to Gemini, which crafts it into a blog post based on the blog.txt template.
  • Output: Saves the result as a Markdown file with a unique, organized filename.

It’s efficient, modular, and handles errors smoothly—perfect for scaling your content efforts.
