Hey everyone! 👋 Welcome back to My Free AI Generator, your go-to hub for everything related to AI tools, generators, and creative automation.

If you’ve ever dreamed of running your own blog that writes posts automatically — without paying for expensive tools — this article is for you.

Today, I’ll walk you through how to build your own AI-powered blog post generator using Google Sheets and completely free tools. No coding experience needed.

By the end of this guide, you’ll have a working system that can generate AI-written blog posts — ready to publish on your Blogger, WordPress, or any content platform.

Let’s dive in 🚀

💡 Why Build a Free AI Blog Post Generator?

Before we start, let’s understand why this is such a game changer.

Most AI writing tools — like Jasper, Writesonic, or Copy.ai — cost between $20 to $100 per month. That’s not cheap for new creators or students.

But with a bit of creativity, you can combine free Google tools and AI text generators to build your own version — 100% free.

Here’s what you’ll achieve:

✅ Generate blog posts from keywords automatically
✅ Use AI tools without coding knowledge
✅ Save time on writing repetitive content
✅ Create SEO-optimized posts quickly
✅ Learn how AI works behind the scenes

So instead of paying monthly fees, you’ll build your own AI-powered system.

⚙️ Tools You’ll Need

You only need three things, all free:

Tool Purpose Access
Google Sheets To manage titles, keywords, prompts, and results sheets.google.com
Google Apps Script To automate the process Built into Google Sheets
Free AI Generator / API To create content Example: Hugging Face API, OpenAI Free Tier, or other open models

Optional tools (for bonus automation):

  • Canva for AI thumbnails

  • Google Docs for editing & formatting

  • Blogger/WordPress for publishing

🧱 Step 1: Setting Up Your Google Sheet

Start by opening a new Google Sheet. You’ll create a simple table with the following columns:

Column Description
A: Blog Title The topic you want to write about
B: Keywords Main SEO keywords
C: Prompt The AI command or text prompt
D: AI Output The final generated content

Example:

Blog Title Keywords Prompt AI Output
How to Start a Blog blogging, SEO Write a blog post on how to start a blog for beginners (AI will fill this)

You’ll type your own blog topics in column A and B.

🧩 Step 2: Connecting Google Apps Script

Now comes the fun part — automating your AI writing.

Here’s how:

  1. Go to Extensions → Apps Script inside your Google Sheet.

  2. Delete any default code.

  3. Paste this sample script (example structure):

function generateAIContent() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var lastRow = sheet.getLastRow();
  for (var i = 2; i <= lastRow; i++) {
    var title = sheet.getRange(i, 1).getValue();
    var keywords = sheet.getRange(i, 2).getValue();
    var prompt = sheet.getRange(i, 3).getValue();
    if (sheet.getRange(i, 4).getValue() === "") {
      var aiOutput = callFreeAI(prompt);
      sheet.getRange(i, 4).setValue(aiOutput);
      Utilities.sleep(2000);
    }
  }
}

function callFreeAI(prompt) {
  var url = "https://api-inference.huggingface.co/models/google/flan-t5-large";
  var payload = {"inputs": prompt};
  var headers = {"Authorization": "Bearer YOUR_FREE_API_KEY"};
  var options = {
    "method": "post",
    "headers": headers,
    "payload": JSON.stringify(payload)
  };
  var response = UrlFetchApp.fetch(url, options);
  var result = JSON.parse(response.getContentText());
  return result[0].generated_text;
}

  1. Replace "YOUR_FREE_API_KEY" with your Hugging Face key (free).

  2. Save and run the script.

Boom! 💥 Your Google Sheet can now generate AI-written content automatically.

🧠 Step 3: Creating the Perfect AI Prompt

The secret behind quality AI writing lies in prompt engineering.

Here’s how you can write powerful prompts for better results:

Type Example Prompt
Informative “Write a 700-word blog post on [topic], include headings and SEO keywords.”
Conversational “Explain [topic] as if you’re talking to your readers, in a friendly tone.”
Review/Comparison “Compare [Tool A] and [Tool B] with pros and cons in detail.”
Step-by-Step Guide “Write a how-to guide on [topic] with steps, examples, and conclusion.”

You can even experiment with tones — formal, casual, friendly, or storytelling.

🧩 Step 4: Auto-Fill and Generate

Once your prompts are ready:

  1. Go back to Google Sheets.

  2. From the toolbar, click Run → generateAIContent().

  3. Wait a few seconds — your sheet will start filling column D with AI-generated posts.

🎉 Congratulations! You’ve just created your very own AI Blog Post Generator using only free tools.

🧾 Example Output

Here’s how it looks before and after automation:

Before After
“How to Start a Blog” (empty output) “Starting a blog in 2025 is easier than ever. Here’s how…” (AI-generated text)
“Benefits of Free AI Tools” (empty output) “Free AI tools are changing how creators work online. Let’s explore the top ones…”

💬 Step 5: Refining and Publishing

Even though AI does the heavy lifting, your final touch is essential.

Here’s how to refine your post:

  1. Copy AI Output → Google Docs

  2. Edit grammar, tone, and SEO keywords

  3. Add images or AI thumbnails (using Canva or Leonardo AI)

  4. Publish on Blogger

💡 Tip: You can even automate Blogger publishing using Google Apps Script Blogger API, but that’s an advanced step for later.

🧭 Pro Tips for Better Results

✔ Use clear, specific prompts — vague inputs produce weak results.
✔ Mix long-tail keywords — improves SEO visibility.
✔ Always edit AI content — to maintain originality.
✔ Experiment with different AI models — some are better for storytelling, others for tutorials.
✔ Use Grammarly or Quillbot — to polish final text.
