AI-Powered Blog Publishing System

This project is an end-to-end, automated content production pipeline built entirely within the Google Workspace ecosystem. It empowers a user to transform a simple, five-line blog idea into a fully drafted, SEO-optimized, and visually enriched blog post in Google Docs, ready for final review and publishing. The system leverages a series of specialized AI agents, orchestrated by Google Apps Script, to handle everything from strategic outlining to creative asset generation.

The Challenge

For content creators and marketing teams, the process of consistently producing high-quality blog content is a significant bottleneck. The manual workflow is slow and prone to inconsistency, involving time-consuming tasks such as:

• Developing a logical structure and detailed outline from a raw idea.

• Writing a comprehensive first draft that adheres to a specific tone.

• Conducting SEO research to generate relevant tags, keywords, and a search-friendly slug.

• Manually searching through past articles to find internal linking opportunities.

• Creating or sourcing relevant, high-quality images to accompany the text.

This entire process can take hours, limiting content output and diverting focus from higher-level strategy.

The Solution: A Step-by-Step Journey

This solution was designed to be intuitive and efficient. Here is a typical workflow from the user’s perspective:

1. Step 1: Idea Submission: The user provides a simple 5-point brief (Draft Title, Audience, Objectives, Tone, Call to Action) in a designated Google Sheet.

2. Step 2: Draft Creation: The user runs “Step 1: Create Blog Post Draft” from a custom menu. The system’s AI agents automatically:

   • Refine the title and create a detailed outline.

   • Write a complete first draft of the article.

   • Analyze the draft to generate SEO metadata (slug, tags, keywords) and insert internal links.

   • Determine optimal locations for images and generate creative prompts.

   • Call the Imagen API to generate all visual assets.

   • Assemble a new Google Doc containing the full raw text and all generated images, correctly sized and placed.

3. Step 3: Final Formatting: The user pastes the new Doc’s URL into the Google Sheet and runs “Step 2: Format Final Document.” The script automatically applies all heading styles (H2, H3), bold, and italic formatting to the document.

4. Step 4: Review & Publish: The user receives a link to a fully drafted and formatted blog post, ready for a final human review before being published.
