How a Regular Engineer Uses ChatGPT to Build Passive Income

AI isn’t just a tool — it’s a cheat code. As an engineer with zero experience in content or business, I wanted to see how far I could stretch £200/month using ChatGPT and a bit of curiosity.

Here are 5 ways I use AI to start earning online — without needing to be a tech genius or full-time creator.

1. 📝 Writing Blog Posts (Like This One)

I used to think blogging was only for writers — until I discovered how much easier tools like ChatGPT made the process.

These days, I use it to bounce around topic ideas, build rough drafts, and sharpen my titles and intros. It’s not perfect out of the box, but with a few tweaks in my own voice, it saves me hours.

This entire blog is built on that system — including this post.
💡 I set it all up with Hostinger because it’s simple and beginner-friendly (especially if, like me, you’re figuring it out as you go).

2. 📚 Selling eBooks and Digital Guides

One of the first things I tried was turning ideas into eBooks. I’d outline the structure, get ChatGPT to help fill in the blanks, then clean it up and design it in Canva.

I’ve sold simple guides on topics like budgeting and digital side hustles through platforms like Gumroad and Etsy — and you don’t need to be an expert to get started.

3. 🖥️ Speeding Up Freelance Work

When I started offering services on Fiverr, AI became my silent co-pilot. From writing short descriptions to drafting emails or polishing bios, it sped up everything.

It’s especially useful for repetitive stuff — things that used to take me 30 minutes now take five.

4. 🧠 Creating Courses or Templates

I’ve also used AI to help structure digital products like planners, checklists, or course outlines.

If I want to build something like “How to Start a Side Hustle,” I’ll use AI to organize the steps, then turn that into a product or even a video script.

It’s a creative jump-start — not a replacement, just a helper.

5. 💬 Running a Faceless TikTok Channel

This one’s a fun side hustle. I write scripts using AI, record voiceovers using free tools, then edit them with CapCut.

You don’t need to show your face — just focus on a niche. Once you build an audience, there are loads of ways to earn: affiliate links, digital products, even shoutouts.

🔧 Final Thoughts (Engineer’s Take)

I don’t have a marketing background. I’m just an engineer trying to build something better with the £200/month I used to waste on stuff I didn’t need.

AI hasn’t made me rich — but it has made everything feel possible. It’s like a productivity boost on tap.

If you’re curious, pick one of these ideas and give it a go this week. You don’t need experience. You just need a start.
