I used only GPTs to create and publish a complete blog with images, banners, and HTML in just three days. In this post, I’ll share exactly what worked, what didn’t, and what you can learn from my experiment to speed up your own blog creation process.
🚀 I Built a Blog in 3 Days Using GPTs — Here's What I Learned
Can you fully build and launch a blog using only GPTs — no external tools, no manual editing? I tested this idea for three days. Here's a breakdown of what worked, what surprised me, and what I’d recommend if you're trying to do the same.
📌 Day 1: Setting Up the Structure
I began with custom GPTs that I trained to generate blog outlines, prompt-based HTML, and banner image descriptions. The initial setup took about 2 hours, and I was able to get consistent, structured outputs that matched my FM blog format.
📌 Day 2: Visual & Banner Automation
Using MidJourney prompts generated by GPT, I created all thumbnail and body images for the blog post. It saved a huge amount of time because I no longer needed to brainstorm visuals from scratch. Each prompt was tied directly to the blog section.
📌 Day 3: Speed, Consistency & Publishing
By the third day, the system became smoother. I could generate, format, and schedule a post (including banners and full HTML) in under 45 minutes. The real advantage was consistency — no broken layout, no missing elements.
🧠 What Surprised Me
- GPTs can maintain consistent style across multiple posts
- HTML generation with subheadings, lists, and spacing worked 95% accurately
- Banners and CTAs tied into actual blog content improved click-through
⚠️ What Didn't Work
- GPTs sometimes repeat keywords unnaturally — minor editing still required
- Occasional missing alt-text in auto-generated image sections
✅ Key Takeaways
Building a blog with GPTs is not only possible — it’s practical. If you build a strong format and prompt system early, you can automate 80% of the process. Add your human touch to the last 20%, and you're publishing at scale.
