I want to start with something that might surprise you.
I do not pay a single dollar for the AI tools I use to make money every month. Not one subscription. Not one premium plan.
Everything I am about to share with you is completely free. And before you roll your eyes and think this is going to be one of those posts that promises the world and delivers nothing — let me be upfront with you. This is not about getting rich overnight. This is about what I personally use, every single day, to earn real extra income on the side. Money that hits my account every month without fail.
I know there are a million blog posts out there talking about AI tools. Most of them read like a product catalog. This one is different because I am not recommending tools I read about somewhere. I am talking about tools I actually open every morning, tools that are sitting in my browser tabs right now as I write this. And the combination of these three free tools completely changed how I work and how much I earn.
Let me walk you through all of it.
Why I Started Looking for Free Tools in the First Place
When I first decided to try making money with AI, I made the mistake of thinking I needed to spend money to make money. I signed up for a couple of paid tools, paid for a month, used them maybe twice, and then cancelled. That was money wasted on tools I did not even understand yet.
So I went back to basics. I challenged myself to build an income stream using only free tools. Partly because I did not want to risk more money, and partly because I wanted to prove to myself that you do not need to spend anything to get started. What I found was that the free versions of the right tools were more than enough — especially when you know how to use them properly.
The three tools I landed on were ChatGPT, Grammarly, and Hemingway Editor. Simple. Unglamorous. But together, they form a system that works.
Tool Number One — ChatGPT (The Engine)
If you have not used ChatGPT yet, I genuinely do not know what you are waiting for. The free version is powerful enough to do everything I am about to describe. You do not need the paid version to start making money. I used the free version for my first three months and made real income during that entire time.
Here is how I actually use it. I do freelance content writing — blog posts, product descriptions, email newsletters — for small businesses and bloggers, mostly based in the US. These clients need content regularly, and they do not always have the time or the skill to write it themselves. That is where I come in.
My process with ChatGPT is not what most people think. I do not just type “write me a blog post about X” and copy paste whatever comes out. That is a recipe for robotic, generic content that any client will immediately see through. Instead, I use ChatGPT in a much more controlled way.
I start by giving it the topic and asking for an outline. Just the structure — the headings and what each section should cover. I look at that outline, move things around if needed, and then prompt ChatGPT section by section. Each prompt is specific. For example, instead of saying “write about indoor plants,” I say something like “write a 200-word section explaining why succulents are perfect for people who travel frequently. Keep it conversational. Mention one specific mistake most beginners make.” That kind of specific prompt gives me something I can actually work with.
The output is never perfect. But it is a strong starting point. And having a strong starting point is everything. The blank page is the hardest part of writing. ChatGPT eliminates the blank page entirely, and that alone saves me hours every week.
The other thing I use ChatGPT for is research. When a client sends me a topic I know nothing about, I ask ChatGPT to give me a quick overview — the key points, common misconceptions, and what the target audience usually cares about. It gets me up to speed in minutes instead of hours. I still verify important facts separately, but it gives me a foundation to work from.
Tool Number Two — Grammarly (The Safety Net)
Here is something I learned the hard way. When you write a lot of content quickly, you make mistakes. Small ones, mostly. A missing comma. A word used twice in the same sentence. A sentence that made sense in your head but reads awkwardly on paper. These are the kinds of errors that slip past you when you are reading your own work because your brain automatically fills in what it expects to see.
Grammarly catches all of that. And the free version does it really well.
Every single piece of content I write goes through Grammarly before it goes to a client. No exceptions. It takes about two minutes and it has saved me from sending out embarrassing mistakes more times than I can count. But more than just catching errors, Grammarly also flags sentences that are unclear or unnecessarily complicated. That feedback has genuinely made me a better writer over time, not just a more accurate one.
There is one thing I want to be clear about though. Grammarly is not a replacement for your own judgment. Sometimes it suggests a change and I disagree with it.
Sometimes the “error” it flags is actually a stylistic choice I made on purpose. You have to read its suggestions critically and decide which ones actually improve the writing. But that only takes a moment, and the habit of running everything through it before sending is one of the best professional habits I have built.
The free version does not have all the advanced features of the premium plan. But for grammar checking, clarity suggestions, and catching basic errors, it does everything you need. I have never felt like I was missing something critical by not upgrading.
Tool Number Three — Hemingway Editor (The Secret Weapon)
This one is the tool most people have never heard of, and honestly it might be the most underrated free writing tool on the internet.
Hemingway Editor analyzes your writing and tells you how easy it is to read. It highlights sentences that are too long, words that are unnecessarily complex, and phrases written in passive voice when active voice would be clearer. It gives your writing a readability grade — and for most online content aimed at a US audience, you want to be around a 6th to 8th grade reading level.
Now before you take that the wrong way — a lower reading level does not mean dumbing things down. It means writing clearly. It means not making your reader work harder than they need to. The most successful writers online write simply. Not because their readers are not intelligent, but because clear, direct writing is just more enjoyable to read. People click away from content that feels like homework.
When I first ran my writing through Hemingway, I was shocked at how many of my sentences were flagged as too long or too complex. I thought I was writing clearly. Hemingway showed me I was not.
And when I started following its suggestions — breaking long sentences into shorter ones, replacing fancy words with simple ones, cutting passive voice — my clients started noticing. One of them actually said, unprompted, that my recent posts felt easier to read and more engaging than before. That was entirely because of changes Hemingway pushed me to make.
You use it by going to hemingwayapp.com and pasting your text directly into the editor. It is completely free to use in the browser. You do not even need to create an account. Just paste, read the highlights, and revise.
How These Three Tools Work Together
Let me walk you through my exact workflow so you can see how all three fit together in practice.
When a client sends me a topic, I open ChatGPT first. I get my outline, then work through the content section by section.
This usually takes about 20 to 30 minutes depending on the length of the piece. Then I take everything I have and paste it into a Google Doc. I read through it fully and start editing — rewriting sentences that sound robotic, adding specific details that make the content feel human, cutting anything that feels unnecessary. This editing pass is where I add my own voice and judgment to the AI’s draft.
Once I am happy with the content, I run it through Grammarly. I go through every suggestion it makes, accept the ones that improve the writing, and ignore the ones that do not. This takes about five to ten minutes.
Then I paste the final version into Hemingway Editor. I look at the highlighted sentences and paragraphs. Anything marked as very hard to read gets rewritten. I aim to get the overall grade down to a 7 or below before I consider the piece done.
The whole process — from blank page to finished, client-ready article — takes me about an hour and a half for a 1000-word piece. Before I developed this workflow, the same piece would take me four or five hours. That is not an exaggeration. The combination of these three tools cut my working time by more than half.
What I Actually Earn and How Realistic This Is
I want to be honest here because I think a lot of people either oversell or undersell what is possible with this kind of work.
When I started, I charged $15 per article. Low, I know. But I needed reviews and I needed to build confidence in my own process. After my first few clients left positive feedback, I raised my rate to $25. Then $35. The quality of my work went up as I got faster and more comfortable with the workflow, and clients noticed.
Right now, writing content using this three-tool system is a consistent source of extra income for me every month. It is not my only income, but it is reliable. Some months are bigger than others depending on how many clients I take on and how much time I have available. But the point is that it is consistent — and it started from zero, with no investment, using tools that are completely free.
The ceiling on what you can earn doing this is honestly pretty high if you commit to it. The more you refine your workflow, the faster you get. The faster you get, the more clients you can handle. And as your reputation builds through reviews and word of mouth, you can keep raising your rates.
The One Thing That Makes This Actually Work
I want to end with something important because I think it is the difference between people who make this work and people who try it once and give up.
These tools are only as good as the effort you put into the editing and the human judgment you bring to the process.
ChatGPT gives you a draft. Grammarly catches your errors. Hemingway makes your writing clearer. But none of them replace the thinking, the creativity, and the professional reliability that a client is actually paying for.
The people who fail at this are the ones who let ChatGPT do everything and then copy paste it straight to a client. That content gets rejected. It feels hollow. Clients can tell.
The people who succeed are the ones who treat AI as a tool that handles the mechanical parts of the work so that their own time and energy can go toward the parts that actually require a human — judgment, tone, accuracy, and quality control.
If you use these three free tools as part of a thoughtful process rather than a shortcut, you will be surprised at what you can build. I was surprised. And I started with zero experience, zero tech skills, and a free ChatGPT account.
That is really all it takes to begin.
