How I Started Earning Money Using AI Tools After Work

As a full-time office worker in Japan, I never imagined I could create a side hustle. Like many others, I thought making extra money required either a lot of time, specialized skills, or upfront capital — none of which I had. After working 9 to 6, all I wanted was dinner and a quiet evening.

But the pressure of rising expenses, plus the desire for financial freedom, made me look for alternatives. That’s when I discovered the power of AI tools — and everything changed.

Why AI Was My Breakthrough

I first stumbled upon ChatGPT on social media. People were using it to write stories, blogs, even emails. I thought: What if I could use it to write articles and make some money on the side?

It sounded too good to be true. But I gave it a shot.

I asked ChatGPT to help me write a short personal essay based on my experience juggling a full-time job while pursuing creative goals. I edited the output, made it sound more like me, and submitted it to Vocal.media — a platform that pays writers based on engagement.

One week later, the article earned me about $5. Not a fortune, but it was proof that this worked. I didn’t need to be a professional writer — I just needed a good idea, a clean draft, and a story worth telling.

Growing My Side Hustle, Step by Step

Encouraged by my first success, I set a goal to write one article a week. I explored different topics like:

• “5 Ways AI Tools Can Help You Make Money After Work”

• “What It’s Like to Be a Foreigner Living in Tokyo”

• “I Used ChatGPT to Write My First Ebook — Here’s What Happened”

One of these articles earned over $40, which blew my mind. I didn’t spend hours writing. Most of the work was done by AI — my role was to personalize, polish, and publish.

I also joined Medium.com and Note.jp (a Japanese platform) to republish my work. The more I wrote, the more comfortable I became. I created templates, used Grammarly and DeepL to refine my English, and started building a tiny audience.

Surprisingly, what started as a financial experiment began to shift my mindset. I no longer came home from work feeling powerless. Even one hour of writing felt productive, like I was slowly reclaiming control over my future. That kind of psychological lift — the belief that you can build something on your own terms — is something money alone can’t buy.

What You Can Learn From My Journey

You don’t need to be an expert to start. You just need a laptop, internet, and curiosity.

Here are a few things I’ve learned:

• Start before you feel ready. Your first few articles may feel imperfect — that’s fine. Publish anyway.

• Use AI as a helper, not a crutch. Let it help you brainstorm, outline, and write drafts, but always inject your voice.

• Focus on consistency. One article a week adds up. Over time, your writing improves — and so does your income.

• Learn from feedback. On platforms like Medium or Vocal, reader comments are golden. They’ll tell you what resonates.

Now, I’m exploring new ways to monetize my content, like turning articles into ebooks, creating mini-courses, and even coaching other non-native writers who want to try AI-assisted writing.

My goal is to replace at least 30% of my salary with AI-generated income within six months — and I’m well on my way.

Final Thought

If you’re stuck, tired, and unsure where to start — try writing with AI.

It won’t make you rich overnight, but it might just change your mindset, give you confidence, and open the door to something bigger.

And sometimes, that’s all you need to get started.
